Detailed Description

draws an area plot.

vtkPlotArea is used to render an area plot. An area plot (sometimes called a range plot) renders a filled region between the selected ymin and ymax arrays. To specify the x array and ymin/ymax arrays, use the SetInputArray method with array index as 0, 1, or 2, respectively.

	)

virtual

Paint legend event for the plot, called whenever the legend needs the plot items symbol/mark/line drawn.

A rect is supplied with the lower left corner of the rect (elements 0 and 1) and with width x height (elements 2 and 3). The plot can choose how to fill the space supplied. The index is used by Plots that return more than one label.

Reimplemented from vtkPlot.
