Hi,
After a while away from matplotlib I am back working on some old code. I
decided to switch to python 3 (bad idea?) and I am having problems with
backends. I used to use GTKAgg, it worked ok, but it doesn't seem to work
with python 3?
1- What are my choices running python 3 and matplotlib from source (I
started following the master branch to avoid some bugs in the past, and kept
using it since)? I did look in the docs and searched the lists, but I
couldn't find a clear answer.
2- Is it discouraged to use matplotlib with python 3?
3- I got the Qt4Agg backend sort of working. It displays my figures ok, but
throws exceptions related to some key events I have set up. See below for
backtrace. unichr() has disappeared in python 3, but somehow the backend is
still using it?
Sorry about the post becoming a bit messy.
Jorge
