[Paraview] Cumulative Distribution Function

[Moreland, Kenneth]

LD,

I don't think there is any built in function in ParaView, but you can convert a histogram to a cumulative distribution by applying the Python Programmable Filter with the following script:


import numpy

inarray = inputs[0].RowData['bin_values']

cumdist = numpy.cumsum(inarray)

output.RowData.append(cumdist, 'cumulative_distribution')


I noticed that when you apply the filter, ParaView wants to show it in a spreadsheet view. However, it works if you make it visible in the bar chart view created for the histogram. You can also create a line chart view and display it there.

Hope that helps.

Subject: [EXTERNAL] [Paraview] Cumulative Distribution Function

Hello,

Is it possible to plot a cumulative distribution function  for the histogram data in Paraview? Am trying to generate an 'S' Curve and superimpose on top of the histogram data.

Thanks,

LD
