[Paraview] [EXTERNAL] Possibilities of using different color ramps for different extractions of the same dataset?

[Scott, W Alan]

Your question obviously has to do with python scripts, however in ParaView this can be done using the Calculator filter.  We just create another copy of the data with a different name – and then ParaView will allow you to use a different color table for this second array.  Could you do something like that?  Or, did I miss your point?

Subject: [EXTERNAL] [Paraview] Possibilities of using different color ramps for different extractions of the same dataset?


Dear all,

I am creating extractions from a NetCDF data. I am wondering if I can create separate color ramps for different extractions of the same array for comparisons.   I tried the process within Paraview Desktop but I was not able to set different color ramps because the array name is the same for all extractions.



Sample code:
 SetActiveSource(ncreader)
    ExtractSubset1 = ExtractSubset()
    ExtractSubset1.VOI = [0, 50,0, 50,0, 8]

    DataRepresentation1 = Show(ExtractSubset1)
    DataRepresentation1.Representation = 'Volume'
    DataRepresentation1.ColorArrayName = ('CELL_DATA', varname)
    DataRepresentation1.ColorAttributeType = 'CELL_DATA'
    DataRepresentation1.LookupTable  = GetLookupTableForArray(​varname...





Any suggestions?



Thanks,

Jing
