compute a 2D histogram between two columns of an input vtkTable.
This class computes a 2D histogram between two columns of an input vtkTable. Just as with a 1D histogram, a 2D histogram breaks up the input domain into bins, and each pair of values (row in the table) fits into a single bin and increments a row counter for that bin.
To use this class, set the input with a table and call AddColumnPair(nameX,nameY), where nameX and nameY are the names of the two columns to be used.
In addition to the number of bins (in X and Y), the domain of the histogram can be customized by toggling the UseCustomHistogramExtents flag and setting the CustomHistogramExtents variable to the desired value.
