vtkPairwiseExtractHistogram2D

Section: Visualization Toolkit Infovis Classes

Usage

This class computes a 2D histogram between all adjacent pairs of columns of an input vtkTable. Internally it creates multiple vtkExtractHistogram2D instances (one for each pair of adjacent table columns). It also manages updating histogram computations intelligently, only recomputing those histograms for whom a relevant property has been altered.

Note that there are two different outputs from this filter. One is a table for which each column contains a flattened 2D histogram array. The other is a vtkMultiBlockDataSet for which each block is a vtkImageData representation of the 2D histogram.

To create an instance of class vtkPairwiseExtractHistogram2D, simply invoke its constructor as follows

  obj = vtkPairwiseExtractHistogram2D
