Hi,
Besides Yoshimi's way, you should be able to do something like the
following from pvpython, pvbatch or Python shell.
yourfilter.PointData.GetArray(<arrayname>).GetRange() # or CellData
For example, for a Python script for a Wavelet source you would do the
following:
w = Wavelet()
w.UpdatePipeline() # needed to execute the pipeline to create the output
w.PointData.GetArray("RTData").GetRange()
This will work for the output of a filter that returns a regular VTK data
set or a multiblock data set. If you want the range for only a single block
of a multiblock I'd recommend using the Extract Block filter to get that
block. It should be a shallow copy of the data set to do that so it should
be very fast, even if you don't need the output of the Extract Block filter
for anything else.
Best,
Andy
