Detailed Description

Legend item to display categorical data.

vtkCategoryLegend will display a label and color patch for each value in a categorical data set. To use this class, you must first populate a vtkScalarsToColors by using the SetAnnotation() method. The other input to this class is a vtkVariantArray. This should contain the annotated values from the vtkScalarsToColors that you wish to include within the legend.
