Hi Alan,
You get the array object from the source/reader/filter's point data. for
example
w = Wavelet()
wa = w.PointData.GetArray('RTData')
See if this example doesn't help:

Hello,
I am trying to use paraview.simple python interface to assign a custom color
map, but I can't seem to get it to work with even the default color maps. For
example
AssignLookupTable("nodal_eqps", "Warm")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Applications/paraview.app/Contents/Python/paraview/simple.py", line
770, in AssignLookupTable
return _GetLUTReaderInstance().GetLUT(arrayObject, LUTName, rangeOveride)
File "/Applications/paraview.app/Contents/Python/paraview/lookuptable.py",
line 234, in GetLUT
range = self.__GetRange(aArray,aRangeOveride)
File "/Applications/paraview.app/Contents/Python/paraview/lookuptable.py",
line 301, in __GetRange
nComps = aArray.GetNumberOfComponents()
AttributeError: 'str' object has no attribute 'GetNumberOfComponents'
I have been looking at
http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/_modules/paraview/simple.html#AssignLookupTable
and it appears I need to pass "AssignLookupTable" an "arrayObject". The "arrayname" called "nodal_eqps"
works fine with "GetLookupTableForArray", but I don't know how to create an "arrayObject" from this "arrayname".
Thanks for any help you can lend.
