Syntax

Description

dsScatterPlot(DS) give a 2D scatter plot of the dataset stored in DS.

• DS: data to be displayed
  • DS.input: input part
  • DS.output: output part (this part could be missing for DC)
  • DS.dataName: data name (or description)
  • DS.inputName: data input name
  • DS.annotation: annotation for each data point

dsScatterPlot(DS, opt) use the info in opt to show annotation or legend.

• opt.showAnnotation: 1 to show the annotation of a data instance (when the cursor is near the data instance)
• opt.showLegend: 1 to show the legend is shown.

Example

dataCount=100;
DS.input=2*rand(2, dataCount)-1;
DS.output=1+(DS.input(1,:)+DS.input(2,:)>0);
DS.dataName='Test Data (Move to a data point to show its index)';
for i=1:length(DS.output)
	DS.annotation{i}=sprintf('Data point %d\n(%f, %f)', i, DS.input(1,i), DS.input(2,i));
end
opt=dsScatterPlot('defaultOpt');
opt.showAnnotation=1;
dsScatterPlot(DS, opt);

Warning: Ignoring extra legend entries.
