[Mist-support] MIST Test Code Error

[Jacob Barhak]

Hi Everett,

It seems that the new version of Anaconda uses by default a new version of
Matplotlib that breaks previous MIST code.

If you wish to use MIST 0_92_0_0 with the plot capability, you should
downgrade Matplotlib. Within anaconda, you can do this by using the command:

conda install matplotlib=1.3.1

This worked on my windows machine. And is a suitable ad hoc solution if you
have no code that depends on a newer matplotlib version.

Note that the plot capability is related to the MIST script
CreatePlotsFromCSV.py. This script is rarely used for basic modeling and
simulation, and you can use other MIST capabilities without changing the
matplotlib version, as long as you ignore the plot capabilities in the
CreatePlotsFromCSV.py script.

If TestCode.py does not report any other error, you should be good to
proceed. Yet it is better to test this at least once by using the
matplotlib downgrade command.

I will check downstream to see what was upgraded in Matplotlib to avoid
this issue in the future and may provide other solutions. I also opened an
issue in Github to address this.

Let me know if you encounter any other issues.

Yet hopefully, this solution will allow you to proceed for now.

          Jacob
