// .NAME vtkPlotFunctionalBag - Class for drawing an XY line plot or bag
// given two columns from a vtkTable.
//
// .SECTION Description
// Depending on the number of components, this class will draw either
// a line plot (for 1 component column) or, for two components columns,
// a filled polygonal band (the bag) going from the first to the second
// component on the Y-axis along the X-axis. The filter
// vtkExtractFunctionalBagPlot is intended to create such "bag" columns.
//
