Hi,

I can't get the ''tst_plt.py'' example to work. Log below:

Hi Victor, have you tried running the examples with matplotlib 2.0.0? The Kivy Garden matplotlib integration is currently not compatible with matplotlib versions 2.1 to the latest 3.0.0 because backend_kivy.py calls weight_as_number() which was deprecated in matplotlib 2.1.

Try running the examples on a virtual environment with matplotlib 2.0.0. You can install it by running:

python -m pip install -U --force-reinstall matplotlib==2.0.0

That worked. Thanks!

Just out of curiosity: is that the weight_as_number() deprecation the only thing preventing the use of newer versions of matplotlib? Is that hard to fix?

The weight thing has already been fixed. Give master a try and let us know (with a new issue) if it's still broken.
