colormap changes

[zeneofa]

Hi,

Would it be possible to expose a cmap kwargs for the respective plots? The accent colours on certain devices make it difficult, especially for colour blind individuals, to distinguish the colours. I used the set13 or paired colormaps from palettable.colorbrewer. It would be nice if the user can supply his/her own colour map.

@zeneofa yes, definitely! Are you willing to put in a PR for this?

[zeneofa]

sure, I can put something together :), will have to be a bit later though...

[ericmjl]

Not a problem. I'm also a bit swamped at the moment, which is why I asked 😄. Looking forward to the PR!

Some things that I can think of that will help with usability include:

• docstrings
• error messages for invalid colormaps
• an example use case that can be executed.

Work in progress branch node_cmap.

It is missing

• Error handling
• Tests

Anyone willing to take a crack at finishing the implementation is more than welcome.
