<div dir="ltr"><div>Hi Alan,</div><div><br></div>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.<div>

<div>After looking at this, yep – it’s a bug. I wrote it up as bug number 14816, with a good example using can.exo.</div>
<div> </div>
<div>I like what you wrote below – max-per-block, or maxPerBlock?</div>

<div>Simply max(von_mises) doesn't do it? The calculator is supposed to convert scalars to arrays automatically but maybe there is an issue there...</div>
<div> </div>
<div>PS: This is somewhat ironic. I am working on changes to support things like min/max over all blocks. Those changes would make min/max over block impossible :-) So I guess we want both. What would a good function name for XXX per block be?</div>

<div>Hi,</div>
<div>I am coloring blocks by the maximum value of a variable that occurs within that given block. I am dealing with a large number of blocks, so I don't want to extract each block and color one by one.</div>
<div> </div>
<div>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:</div>
<div> </div>
<div>Expression: ((von_mises - von_mises)+1)*max(von_mises)</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>Thanks,</div>
<div>Alan</div>
