[vtkusers] vtkChartHistogram2D - smoothing the colour boundaries

[John Platt]

Hi,

I have displayed some vtkImageData as a map in vtkChartHistogram2D. The boundaries between the adjacent colours appear to follow the cell edges as though each cell has been coloured with a single scalar. I am looking to obtain the same as a colour map of equivalent polydata using point scalars. Does any one have any ideas on how this can be done?

Many thanks,

John.
