You get the array object from the source/reader/filter's point
data. for example <br>
<blockquote>w = Wavelet()<br>
wa = w.PointData.GetArray('RTData')<br>
</blockquote>
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
</pre>
<blockquote type="cite">
<blockquote type="cite">
<blockquote type="cite">
<pre wrap="">AssignLookupTable("nodal_eqps", "Warm")
</pre>
</blockquote>
</blockquote>
</blockquote>
<pre wrap="">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
<a class="moz-txt-link-freetext" href="http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/_modules/paraview/simple.html#AssignLookupTable">http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/_modules/paraview/simple.html#AssignLookupTable</a>
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.
