COMPAT: mpl 2.0.0

[jreback]

seems @tacaswell / @mdboom have been busy

https://github.com/matplotlib/matplotlib/releases/tag/v2.0.0b1

we should test with this.

is this going up on a conda-forge dev channel? (is there such a thing)?

[tacaswell]

conda install -c conda-forge/label/rc -c conda-forge matplotlib

pandas master

[tacaswell]

You need cycler >= 0.10. Should have pulled that from conda-forge

[jreback]

hmm, maybe needs to be part of your recipe?

[sinhrks]

There looks some errors / failures (most of them are caused by figure size check). Will dig in.

Can we add one more SLOW build using mpl2.0 on Travis with allowed failure?

@sinhrks sure. is 2.0 rc available on a channel somewhere?

[sinhrks]

Not yet. Will try to built from source if it's not available until I need.

[jorisvandenbossche]

I think it is available on conda-forge: https://anaconda.org/conda-forge/matplotlib/labels (edit: at least the beta, not rc)

[tacaswell]

There is no rc yet, should be one 'soon'
