vtkStringToCategory
Section: Visualization Toolkit Infovis Classes
Usage
vtkStringToCategory creates an integer array named "category" based on the
values in a string array. You may use this filter to create an array that
you may use to color points/cells by the values in a string array. Currently
there is not support to color by a string array directly.
The category values will range from zero to N-1,
where N is the number of distinct strings in the string array. Set the string
array to process with SetInputArrayToProcess(0,0,0,...). The array may be in
the point, cell, or field data of the data object.
To create an instance of class vtkStringToCategory, simply
invoke its constructor as follows
obj = vtkStringToCategory
