Hi, after chmod +x, it created a nice histogram of elevation.10m. So I tried on floating point image created by some process. here is the problem: Traceback (most recent call last): File /home/yann/histogram_mpldemo.py, line 173, in module main() File /home/yann/histogram_mpldemo.py,

Re: [GRASS-dev] matplotlib example script

The code is pretty simple. I would guess that NAN data could be discarded when making the list that is histogrammed. I'm kind of surprised that it shows up as r.stats is run to discard nulls. But I guess these aren't seen as nulls by r.stats. Michael __ C.

I revised the histogram_mpldemo.py script according to many of Glynn's suggests. I also added the option of creating the output file in png, pdf, ps, eps, and svg. As before, I've posted it at: histogram_mpldemo.py along with an example output: testhist.pdf I also posted another script
