<p class="MsoNormal" style="margin-left:.5in">I am almost done completely rewriting the Python code under this filter. We'll make sure that this bug is addressed as part of the rewrite. I have global min/max/std deviation etc. working very nicely. I'll add
support for min/max per block. I'll call them min_per_block(), max_per_block() etc.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">I'm currently using the python calculator to do this, since the function "max()" returns block-by-block maximum (scalar), which is what I want.
The issue is that paraview doesn't return the returned value as an array, so using the maximum values per block directly in an expression doesn't work. I'm using a pretty sad-looking syntax to get the job done. My expression is something along the lines
of:<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">So, I'm creating an array of 1's for each cell and then scaling it by the maximum value in a given block. There must be a better way of doing this,
right? Something like "max_by_block()" or "create_cell_array_ones()." If not, perhaps that could become a feature request.<o:p></o:p></span></p>
