// .NAME vtkBarChartActor - create a bar chart from an array
// .SECTION Description
// vtkBarChartActor generates a bar chart from an array of numbers defined in
// field data (a vtkDataObject). To use this class, you must specify an input
// data object. You'll probably also want to specify the position of the plot
// be setting the Position and Position2 instance variables, which define a
// rectangle in which the plot lies. There are also many other instance
// variables that control the look of the plot includes its title and legend.
//
// Set the text property/attributes of the title and the labels through the
// vtkTextProperty objects associated with these components.
