pyside2 matplotlib backend

[rth]

I was wondering if there is any recommended way to use builds from this feedstock in combination with another matplotlib backend such as pyside2?

I see that pyqt5 is pinned at build time; does it mean that installing matplotlib,

conda install -c conda-forge matplotlib

and then force installing pyside2,

conda uninstall --force pyqt5
conda install -c conda-forge --force pyside2

is not a good idea with respect to binary compatibility? Would something like be impacted by the support of optional dependencies in conda/conda#4982?

I think #2 would address this.

I’ve opened PR #157, which would address this. With that version of the package, you would just need to install the desired Python Qt wrapper package alongside matplotlib:

conda install matplotlib pyside

Great, thank you @marcelm !
