// .NAME vtkPlotArea - draws an area plot.
// .SECTION Description
// 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.
