Modifying Properties

You can set and query graphics object properties in two ways:

To change the default value of properties see Setting Default Property Values.

Axes Property Descriptions

This section lists property names along with the types of values each accepts. Curly braces { } enclose default values.

ALim                         [amin, amax]

Alpha axis limits. A two-element vector that determines how MATLAB maps the AlphaData values of surface, patch and image objects to the figure's alphamap. amin is the value of the data mapped to the first alpha value in the alphamap, and amax is the value of the data mapped to the last alpha value in the alphamap. Data values in between are linearly interpolated across the alphamap, while data values outside are clamped to either the first or last alphamap value, whichever is closest.

When ALimMode is auto (the default), MATLAB assigns amin the minimum data value and amax the maximum data value in the graphics object's AlphaData. This maps AlphaData elements with minimum data values to the first alphamap entry and those with maximum data values to the last alphamap entry. Data values in between are mapped linearly to the values

If the axes contains multiple graphics objects, MATLAB sets ALim to span the range of all objects' AlphaData (or FaceVertexAlphaData for patch objects).

ALimMode                     {auto} | manual

Alpha axis limits mode. In auto mode, MATLAB sets the ALim property to span the AlphaData limits of the graphics objects displayed in the axes. If ALimMode is manual, MATLAB does not change the value of ALim when the AlphaData limits of axes children change. Setting the ALim property sets ALimMode to manual.

AmbientLightColor            ColorSpec

The background light in a scene. Ambient light is a directionless light that shines uniformly on all objects in the axes. However, if there are no visible light objects in the axes, MATLAB does not use AmbientLightColor. If there are light objects in the axes, the AmbientLightColor is added to the other light sources.

AspectRatio                  (Obsolete)

This property produces a warning message when queried or changed. It has been superseded by the DataAspectRatio[Mode] and PlotBoxAspectRatio[Mode] properties.

Box                          on | {off}

Axes box mode. This property specifies whether to enclose the axes extent in a box for 2-D views or a cube for 3-D views. The default is to not display the box.

BusyAction                   cancel | {queue}

Callback routine interruption. The BusyAction property enables you to control how MATLAB handles events that potentially interrupt executing callback routines. If there is a callback routine executing, subsequently invoked callback routines always attempt to interrupt it. If the Interruptible property of the object whose callback is executing is set to on (the default), then interruption occurs at the next point where the event queue is processed. If the Interruptible property is off, the BusyAction property (of the object owning the executing callback) determines how MATLAB handles the event. The choices are:

ButtonDownFcn                string

Button press callback routine. A callback routine that executes whenever you press a mouse button while the pointer is within the axes, but not over another graphics object displayed in the axes. For 3-D views, the active area is defined by a rectangle that encloses the axes.

Define this routine as a string that is a valid MATLAB expression or the name of an M-file. The expression executes in the MATLAB workspace.

CameraPosition               [x, y, z] axes coordinates

The location of the camera. This property defines the position from which the camera views the scene. Specify the point in axes coordinates.

If you fix CameraViewAngle, you can zoom in and out on the scene by changing the CameraPosition, moving the camera closer to the CameraTarget to zoom in and farther away from the CameraTarget to zoom out. As you change the CameraPosition, the amount of perspective also changes, if Projection is perspective. You can also zoom by changing the CameraViewAngle; however, this does not change the amount of perspective in the scene.

CameraPositionMode           {auto} | manual

Auto or manual CameraPosition. When set to auto, MATLAB automatically calculates the CameraPosition such that the camera lies a fixed distance from the CameraTarget along the azimuth and elevation specified by view. Setting a value for CameraPosition sets this property to manual.

CameraTarget                 [x, y, z] axes coordinates

Camera aiming point. This property specifies the location in the axes that the camera points to. The CameraTarget and the CameraPosition define the vector (the view axis) along which the camera looks.

CameraTargetMode             {auto} | manual

Auto or manual CameraTarget placement. When this property is auto, MATLAB automatically positions the CameraTarget at the centroid of the axes plotbox. Specifying a value for CameraTarget sets this property to manual.

CameraUpVector               [x, y, z] axes coordinates

Camera rotation. This property specifies the rotation of the camera around the viewing axis defined by the CameraTarget and the CameraPosition properties. Specify CameraUpVector as a three-element array containing the x, y, and z components of the vector. For example, [0 1 0] specifies the positive y-axis as the up direction.

The default CameraUpVector is [0 0 1], which defines the positive z-axis as the up direction.

CameraUpVectorMode           {auto} | manual

Default or user-specified up vector. When CameraUpVectorMode is auto, MATLAB uses a value of [0 0 1] (positive z-direction is up) for 3-D views and [0 1 0] (positive y-direction is up) for 2-D views. Setting a value for CameraUpVector sets this property to manual.

CameraViewAngle              scalar greater than 0 and less than or equal to
                             180 (angle in degrees)

The field of view. This property determines the camera field of view. Changing this value affects the size of graphics objects displayed in the axes, but does not affect the degree of perspective distortion. The greater the angle, the larger the field of view, and the smaller objects appear in the scene.

CameraViewAngleMode          {auto} | manual

Auto or manual CameraViewAngle. When in auto mode, MATLAB sets CameraViewAngle to the minimum angle that captures the entire scene (up to 180°).

The following table summarizes MATLAB's automatic camera behavior.

Children                     vector of graphics object handles

Children of the axes. A vector containing the handles of all graphics objects rendered within the axes (whether visible or not). The graphics objects that can be children of axes are images, lights, lines, patches, surfaces, and text. You can change the order of the handles and thereby change the stacking of the objects on the display.

The text objects used to label the x-, y-, and z-axes are also children of axes, but their HandleVisibility properties are set to callback. This means their handles do not show up in the axes Children property unless you set the Root ShowHiddenHandles property to on.

CLim                         [cmin, cmax]

Color axis limits. A two-element vector that determines how MATLAB maps the CData values of surface and patch objects to the figure's colormap. cmin is the value of the data mapped to the first color in the colormap, and cmax is the value of the data mapped to the last color in the colormap. Data values in between are linearly interpolated across the colormap, while data values outside are clamped to either the first or last colormap color, whichever is closest.

When CLimMode is auto (the default), MATLAB assigns cmin the minimum data value and cmax the maximum data value in the graphics object's CData. This maps CData elements with minimum data value to the first colormap entry and with maximum data value to the last colormap entry.

If the axes contains multiple graphics objects, MATLAB sets CLim to span the range of all objects' CData.

CLimMode                     {auto} | manual

Color axis limits mode. In auto mode, MATLAB sets the CLim property to span the CData limits of the graphics objects displayed in the axes. If CLimMode is manual, MATLAB does not change the value of CLim when the CData limits of axes children change. Setting the CLim property sets this property to manual.

Clipping                     {on} | off

This property has no effect on axes.

Color                        {none} | ColorSpec

Color of the axes back planes. Setting this property to none means the axes is transparent and the figure color shows through. A ColorSpec is a three-element RGB vector or one of MATLAB's predefined names. Note that while the default value is none, the matlabrc.m file may set the axes color to a specific color.

ColorOrder                   m-by-3 matrix of RGB values

Colors to use for multiline plots. ColorOrder is an m-by-3 matrix of RGB values that define the colors used by the plot and plot3 functions to color each line plotted. If you do not specify a line color with plot and plot3, these functions cycle through the ColorOrder to obtain the color for each line plotted. To obtain the current ColorOrder, which may be set during startup, get the property value:

Note that if the axes NextPlot property is set to replace (the default), high-level functions like plot reset the ColorOrder property before determining the colors to use. If you want MATLAB to use a ColorOrder that is different from the default, set NextPlot to replacechildren. You can also specify your own default ColorOrder.

CreateFcn                    string

Callback routine executed during object creation. This property defines a callback routine that executes when MATLAB creates an axes object. You must define this property as a default value for axes. For example, the statement,

defines a default value on the Root level that sets the current axes' background color to blue whenever you (or MATLAB) create an axes. MATLAB executes this routine after setting all properties for the axes. Setting this property on an existing axes object has no effect.

The handle of the object whose CreateFcn is being executed is accessible only through the Root CallbackObject property, which can be queried using gcbo.

CurrentPoint                 2-by-3 matrix

Location of last button click, in axes data units. A 2-by-3 matrix containing the coordinates of two points defined by the location of the pointer. These two points lie on the line that is perpendicular to the plane of the screen and passes through the pointer. The 3-D coordinates are the points, in the axes coordinate system, where this line intersects the front and back surfaces of the axes volume (which is defined by the axes x, y, and z limits).

The returned matrix is of the form:

MATLAB updates the CurrentPoint property whenever a button-click event occurs. The pointer does not have to be within the axes, or even the figure window; MATLAB returns the coordinates with respect to the requested axes regardless of the pointer location.

DataAspectRatio              [dx dy dz]

Relative scaling of data units. A three-element vector controlling the relative scaling of data units in the x, y, and z directions. For example, setting this property t o [1 2 1] causes the length of one unit of data in the x direction to be the same length as two units of data in the y direction and one unit of data in the z direction.

Note that the DataAspectRatio property interacts with the PlotBoxAspectRatio, XLimMode, YLimMode, and ZLimMode properties to control how MATLAB scales the x-, y-, and z-axis. Setting the DataAspectRatio will disable the stretch-to-fill behavior, if DataAspectRatioMode, PlotBoxAspectRatioMode, and CameraViewAngleMode are all auto. The following table describes the interaction between properties when stretch-to-fill behavior is disabled.

DataAspectRatioMode          {auto} | manual

User or MATLAB controlled data scaling. This property controls whether the values of the DataAspectRatio property are user defined or selected automatically by MATLAB. Setting values for the DataAspectRatio property automatically sets this property to manual. Changing DataAspectRatioMode to manual disables the stretch-to-fill behavior, if DataAspectRatioMode, PlotBoxAspectRatioMode, and CameraViewAngleMode are all auto.

DeleteFcn                    string

Delete axes callback routine. A callback routine that executes when the axes object is deleted (e.g., when you issue a delete or a close command). MATLAB executes the routine before destroying the object's properties so the callback routine can query these values.

The handle of the object whose DeleteFcn is being executed is accessible only through the Root CallbackObject property, which can be queried using gcbo.

DrawMode                     {normal} | fast

Rendering method. This property controls the method MATLAB uses to render graphics objects displayed in the axes, when the figure Renderer property is painters.

When the figure Renderer is zbuffer, DrawMode is ignored, and hidden surface elimination and object intersection handling are always provided.

FontAngle                    {normal} | italic | oblique

Select italic or normal font. This property selects the character slant for axes text. normal specifies a nonitalic font. italic and oblique specify italic font.

FontName                     A name such as Courier or the string FixedWidth

Font family name. The font family name specifying the font to use for axes labels. To display and print properly, FontName must be a font that your system supports. Note that the x-, y-, and z-axis labels do not display in a new font until you manually reset them (by setting the XLabel, YLabel, and ZLabel properties or by using the xlabel, ylabel, or zlabel command). Tick mark labels change immediately.

Specifying a Fixed-Width Font

If you want an axes to use a fixed-width font that looks good in any locale, you should set FontName to the string FixedWidth:

This eliminates the need to hardcode the name of a fixed-width font, which may not display text properly on systems that do not use ASCII character encoding (such as in Japan where multibyte character sets are used). A properly written MATLAB application that needs to use a fixed-width font should set FontName to FixedWidth (note that this string is case sensitive) and rely on FixedWidthFontName to be set correctly in the end-user's environment.

End users can adapt a MATLAB application to different locales or personal environments by setting the root FixedWidthFontName property to the appropriate value for that locale from startup.m.

Note that setting the root FixedWidthFontName property causes an immediate update of the display to use the new font.

FontSize                     Font size specified in FontUnits

Font size. An integer specifying the font size to use for axes labels and titles, in units determined by the FontUnits property. The default point size is 12. The x-, y-, and z-axis text labels do not display in a new font size until you manually reset them (by setting the XLabel, YLabel, or ZLabel properties or by using the xlabel, ylabel, or zlabel command). Tick mark labels change immediately.

FontUnits                    {points} | normalized | inches |
                              centimeters |
pixels

Units used to interpret the FontSize property. When set to normalized, MATLAB interprets the value of FontSize as a fraction of the height of the axes. For example, a normalized FontSize of 0.1 sets the text characters to a font whose height is one tenth of the axes' height. The default units (points), are equal to 1/72 of an inch.

FontWeight                   {normal} | bold | light | demi

Select bold or normal font. The character weight for axes text. The x-, y-, and z-axis text labels do not display in bold until you manually reset them (by setting the XLabel, YLabel, and ZLabel properties or by using the xlabel, ylabel, or zlabel commands). Tick mark labels change immediately.

GridLineStyle                - | - -| {:} | -. | none

Line style used to draw grid lines. The line style is a string consisting of a character, in quotes, specifying solid lines (-), dashed lines (--), dotted lines(:), or dash-dot lines (-.). The default grid line style is dotted. To turn on grid lines, use the grid command.

HandleVisibility             {on} | callback | off

Control access to object's handle by command-line users and GUIs. This property determines when an object's handle is visible in its parent's list of children. HandleVisibility is useful for preventing command-line users from accidentally drawing into or deleting a figure that contains only user interface devices (such as a dialog box).

Handles are always visible when HandleVisibility is on.

Setting HandleVisibility to callback causes handles to be visible from within callback routines or functions invoked by callback routines, but not from within functions invoked from the command line. This provides a means to protect GUIs from command-line users, while allowing callback routines to have complete access to object handles.

Setting HandleVisibility to off makes handles invisible at all times. This may be necessary when a callback routine invokes a function that might potentially damage the GUI (such as evaluating a user-typed string) and so temporarily hides its own handles during the execution of that function.

When a handle is not visible in its parent's list of children, it cannot be returned by functions that obtain handles by searching the object hierarchy or querying handle properties. This includes get, findobj, gca, gcf, gco, newplot, cla, clf, and close.

When a handle's visibility is restricted using callback or off, the object's handle does not appear in its parent's Children property, figures do not appear in the Root's Currentfigure property, objects do not appear in the Root's CallbackObject property or in the figure's CurrentObject property, and axes do not appear in their parent's Currentaxes property.

You can set the Root ShowHiddenHandles property to on to make all handles visible, regardless of their HandleVisibility settings (this does not affect the values of the HandleVisibility properties).

Handles that are hidden are still valid. If you know an object's handle, you can set and get its properties, and pass it to any function that operates on handles.

HitTest                      {on} | off

Selectable by mouse click. HitTest determines if the axes can become the current object (as returned by the gco command and the figure CurrentObject property) as a result of a mouse click on the axes. If HitTest is off, clicking on the axes selects the object below it (which is usually the figure containing it).

Interruptible                {on} | off

Callback routine interruption mode. The Interruptible property controls whether an axes callback routine can be interrupted by subsequently invoked callback routines. Only callback routines defined for the ButtonDownFcn are affected by the Interruptible property. MATLAB checks for events that can interrupt a callback routine only when it encounters a drawnow, figure, getframe, or pause command in the routine. See the BusyAction property for related information.

Setting Interruptible to on allows any graphics object's callback routine to interrupt callback routines originating from an axes property. Note that MATLAB does not save the state of variables or the display (e.g., the handle returned by the gca or gcf command) when an interruption occurs.

Layer                        {bottom} | top

Draw axis lines below or above graphics objects. This property determines if axis lines and tick marks draw on top or below axes children objects for any 2-D view (i.e., when you are looking along the x-, y-, or z-axis). This is useful for placing grid lines and tick marks on top of images.

LineStyleOrder               LineSpec

Order of line styles and markers used in a plot. This property specifies which line styles and markers to use and in what order when creating multiple-line plots. For example,

sets LineStyleOrder to solid line with asterisk marker, dotted line, and hollow circle marker. The default is (-), which specifies a solid line for all data plotted. Alternatively, you can create a cell array of character strings to define the line styles:

MATLAB supports four line styles, which you can specify any number of times in any order. MATLAB cycles through the line styles only after using all colors defined by the ColorOrder property. For example, the first eight lines plotted use the different colors defined by ColorOrder with the first line style. MATLAB then cycles through the colors again, using the second line style specified, and so on.

You can also specify line style and color directly with the plot and plot3 functions or by altering the properties of the line objects.

Note that, if the axes NextPlot property is set to replace (the default), high-level functions like plot reset the LineStyleOrder property before determining the line style to use. If you want MATLAB to use a LineStyleOrder that is different from the default, set NextPlot to replacechildren. You can also specify your own default LineStyleOrder.

LineWidth                    linewidth in points

Width of axis lines. This property specifies the width, in points, of the x-, y-, and z-axis lines. The default line width is 0.5 points (1 point = 1/72 inch).

NextPlot                     add | {replace} | replacechildren

Where to draw the next plot. This property determines how high-level plotting functions draw into an existing axes.

The newplot function simplifies the use of the NextPlot property and is used by M-file functions that draw graphs using only low-level object creation routines. See the M-file pcolor.m for an example. Note that figure graphics objects also have a NextPlot property.

Parent                       figure handle

Axes parent. The handle of the axes' parent object. The parent of an axes object is the figure in which it is displayed. The utility function gcf returns the handle of the current axes' Parent. You can reparent axes to other figure objects.

PlotBoxAspectRatio           [px py pz]

Relative scaling of axes plotbox. A three-element vector controlling the relative scaling of the plot box in the x-, y-, and z-directions. The plot box is a box enclosing the axes data region as defined by the x-, y-, and z-axis limits.

Note that the PlotBoxAspectRatio property interacts with the DataAspectRatio, XLimMode, YLimMode, and ZLimMode properties to control the way graphics objects are displayed in the axes. Setting the PlotBoxAspectRatio disables stretch-to-fill behavior, if DataAspectRatioMode, PlotBoxAspectRatioMode, and CameraViewAngleMode are all auto.

PlotBoxAspectRatioMode       {auto} | manual

User or MATLAB controlled axis scaling. This property controls whether the values of the PlotBoxAspectRatio property are user defined or selected automatically by MATLAB. Setting values for the PlotBoxAspectRatio property automatically sets this property to manual. Changing the PlotBoxAspectRatioMode to manual disables stretch-to-fill behavior, if DataAspectRatioMode, PlotBoxAspectRatioMode, and CameraViewAngleMode are all auto.

Position                     four-element vector

Position of axes. A four-element vector specifying a rectangle that locates the axes within the figure window. The vector is of the form:

where left and bottom define the distance from the lower-left corner of the figure window to the lower-left corner of the rectangle. width and height are the dimensions of the rectangle. All measurements are in units specified by the Units property.

When axes stretch-to-fill behavior is enabled (when DataAspectRatioMode, PlotBoxAspectRatioMode, CameraViewAngleMode are all auto), the axes are stretched to fill the Position rectangle. When stretch-to-fill is disabled, the axes are made as large as possible, while obeying all other properties, without extending outside the Position rectangle

Projection                   {orthographic} | perspective

Type of projection. This property selects between two projection types:

Selected                     on | off

Is object selected. When you set this property to on, MATLAB displays selection "handles" at the corners and midpoints if the SelectionHighlight property is also on (the default). You can, for example, define the ButtonDownFcn callback routine to set this property to on, thereby indicating that the axes has been selected.

SelectionHighlight           {on} | off

Objects highlight when selected. When the Selected property is on, MATLAB indicates the selected state by drawing four edge handles and four corner handles. When SelectionHighlight is off, MATLAB does not draw the handles.

Tag                          string (GUIDE sets this property)

User-specified object label. The Tag property provides a means to identify graphics objects with a user-specified label. This is particularly useful when constructing interactive graphics programs that would otherwise need to define object handles as global variables or pass them as arguments between callback routines.

For example, suppose you want to direct all graphics output from an M-file to a particular axes, regardless of user actions that may have changed the current axes. To do this, identify the axes with a Tag:

Then make that axes the current axes before drawing by searching for the Tag with findobj:

TickDir                      in | out

Direction of tick marks. For 2-D views, the default is to direct tick marks inward from the axis lines; 3-D views direct tick marks outward from the axis line.

TickDirMode                  {auto} | manual

Automatic tick direction control. In auto mode, MATLAB directs tick marks inward for 2-D views and outward for 3-D views. When you specify a setting for TickDir, MATLAB sets TickDirMode to manual. In manual mode, MATLAB does not change the specified tick direction.

TickLength                   [2DLength 3DLength]

Length of tick marks. A two-element vector specifying the length of axes tick marks. The first element is the length of tick marks used for 2-D views and the second element is the length of tick marks used for 3-D views. Specify tick mark lengths in units normalized relative to the longest of the visible X-, Y-, or Z-axis annotation lines.

Title                        handle of text object

Axes title. The handle of the text object that is used for the axes title. You can use this handle to change the properties of the title text or you can set Title to the handle of an existing text object. For example, the following statement changes the color of the current title to red:

To create a new title, set this property to the handle of the text object you want to use:

However, it is generally simpler to use the title command to create or replace an axes title:

Type                         string (read only)

Type of graphics object. This property contains a string that identifies the class of graphics object. For axes objects, Type is always set to 'axes'.

UIContextMenu                handle of a uicontextmenu object

Associate a context menu with the axes. Assign this property the handle of a Uicontextmenu object created in the axes' parent figure. Use the uicontextmenu function to create the context menu. MATLAB displays the context menu whenever you right-click over the axes.

Units                        inches | centimeters | {normalized} |
                             points | pixels | characters

Position units. The units used to interpret the Position property. All units are measured from the lower-left corner of the figure window.

UserData                     matrix

User specified data. This property can be any data you want to associate with the axes object. The axes does not use this property, but you can access it using the set and get functions.

View                         Obsolete

The functionality provided by the View property is now controlled by the axes camera properties - CameraPosition, CameraTarget, CameraUpVector, and CameraViewAngle. See the view command.

Visible                      {on} | off

Visibility of axes. By default, axes are visible. Setting this property to off prevents axis lines, tick marks, and labels from being displayed. The visible property does not affect children of axes.

XAxisLocation                top | {bottom}

Location of x-axis tick marks and labels. This property controls where MATLAB displays the x-axis tick marks and labels. Setting this property to top moves the x-axis to the top of the plot from its default position at the bottom.

YAxisLocation                right | {left}

Location of y-axis tick marks and labels. This property controls where MATLAB displays the y-axis tick marks and labels. Setting this property to right moves the y-axis to the right side of the plot from its default position on the left side. See the plotyy function for a simple way to use two y-axes.

Properties That Control the X-, Y-, or Z-Axis
XColor, YColor, ZColor       ColorSpec

Color of axis lines. A three-element vector specifying an RGB triple, or a predefined MATLAB color string. This property determines the color of the axis lines, tick marks, tick mark labels, and the axis grid lines of the respective x-, y-, and z-axis. The default color axis color is black. See ColorSpec for details on specifying colors.

XDir, YDir, ZDir             {normal} | reverse

Direction of increasing values. A mode controlling the direction of increasing axis values. axes form a right-hand coordinate system. By default:

XGrid, YGrid, ZGrid          on | {off}

Axis gridline mode. When you set any of these properties to on, MATLAB draws grid lines perpendicular to the respective axis (i.e., along lines of constant x, y, or z values). Use the grid command to set all three properties on or off at once.

XLabel, YLabel, ZLabel       handle of text object

Axis labels. The handle of the text object used to label the x, y, or z-axis, respectively. To assign values to any of these properties, you must obtain the handle to the text string you want to use as a label. This statement defines a text object and assigns its handle to the XLabel property:

MATLAB places the string 'axis label' appropriately for an x-axis label. Any text object whose handle you specify as an XLabel, YLabel, or ZLabel property is moved to the appropriate location for the respective label.

Alternatively, you can use the xlabel, ylabel, and zlabel functions, which generally provide a simpler means to label axis lines.

XLim, YLim, ZLim             [minimum maximum]

Axis limits. A two-element vector specifying the minimum and maximum values of the respective axis.

Changing these properties affects the scale of the x-, y-, or z-dimension as well as the placement of labels and tick marks on the axis. The default values for these properties are [0 1].

XLimMode, YLimMode, ZLimMode {auto} | manual

MATLAB or user-controlled limits. The axis limits mode determines whether MATLAB calculates axis limits based on the data plotted (i.e., the XData, YData, or ZData of the axes children) or uses the values explicitly set with the XLim, YLim, or ZLim property, in which case, the respective limits mode is set to manual.

XScale, YScale, ZScale       {linear} | log

Axis scaling. Linear or logarithmic scaling for the respective axis. See also loglog, semilogx, and semilogy.

XTick, YTick, ZTick          vector of data values locating tick marks

Tick spacing. A vector of x-, y-, or z-data values that determine the location of tick marks along the respective axis. If you do not want tick marks displayed, set the respective property to the empty vector, [ ]. These vectors must contain monotonically increasing values.

XTickLabel, YTickLabel, ZTickLabelstring

Tick labels. A matrix of strings to use as labels for tick marks along the respective axis. These labels replace the numeric labels generated by MATLAB. If you do not specify enough text labels for all the tick marks, MATLAB uses all of the labels specified, then reuses the specified labels.

For example, the statement,

labels the first four tick marks on the x-axis and then reuses the labels until all ticks are labeled.

Labels can be specified as cell arrays of strings, padded string matrices, string vectors separated by vertical slash characters, or as numeric vectors (where each number is implicitly converted to the equivalent string using num2str). All of the following are equivalent:

Note that tick labels do not interpret TeX character sequences (however, the Title, XLabel, YLabel, and ZLabel properties do).

XTickMode, YTickMode, ZTickMode{auto} | manual

MATLAB or user controlled tick spacing. The axis tick modes determine whether MATLAB calculates the tick mark spacing based on the range of data for the respective axis (auto mode) or uses the values explicitly set for any of the XTick, YTick, and ZTick properties (manual mode). Setting values for the XTick, YTick, or ZTick properties sets the respective axis tick mode to manual.

XTickLabelMode, YTickLabelMode, ZTickLabelMode{auto} | manual

MATLAB or user determined tick labels. The axis tick mark labeling mode determines whether MATLAB uses numeric tick mark labels that span the range of the plotted data (auto mode) or uses the tick mark labels specified with the XTickLabel, YTickLabel, or ZTickLabel property (manual mode). Setting values for the XTickLabel, YTickLabel, or ZTickLabel property sets the respective axis tick label mode to manual.
