// .NAME vtkXYChartRepresentation
// .SECTION Description
// vtkXYChartRepresentation is representation that is used to add vtkPlot
// subclasses to a vtkChartXY instance e.g. adding vtkPlotBar to create a bar
// chart or vtkPlotLine to create a line chart. For every selected series (or
// column in a vtkTable), this class adds a new vtkPlot to the vtkChartXY.
// vtkXYChartRepresentation provides a union of APIs for changing the appearance
// of vtkPlot instances. Developers should only expose the applicable API in the
// ServerManager XML.
//
// To select which type of vtkPlot instances this class will use, you must set
// the ChartType. Refer to vtkChartXY::AddPlot() for details on what the type
// must be.
