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. -berk On Fri, Jun 20, 2014 at 7:30 PM, Scott, W Alan <[email protected]<mailto:[email protected]>> wrote: Berk, After looking at this, yep – it’s a bug. I wrote it up as bug number 14816, with a good example using can.exo. I like what you wrote below – max-per-block, or maxPerBlock? Alan From the ParaView e-mail list: 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... 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? -berk On Mon, Jun 9, 2014 at 6:24 PM, Scott, W Alan <[email protected]<mailto:[email protected]>> wrote: Hi, 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. 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: Expression: ((von_mises - von_mises)+1)*max(von_mises) 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.
