Problem description

xarrays plotting module is awesome because it detects automatically if the data is divergent or not and adjusts the colormap accordingly.

But what if I do not particularly like the default colormap choice for either data type (e.g. my current boss is not a fan of matplotlibs viridis)?

@shoyer mentioned on stackexchange that this is not currently possible.

I would be happy to submit a PR, if I can get some guidance on where to implement this.

What does everyone think about a syntax this shoule be implemented with?

Something like:

with xr.set_options(diverging_cmap='RdYlBl'): ... with xr.set_options(nondiverging_cmap='magma'): .... Or is there a better way to do this? I would personally prefer to be able to set this at the beginning of a notebook, so that it is applied to all following plots. Maybe something like the mpl.rcparams is a way to go here?
