scatter: fix marker kwarg bug. Closes #4073, #3895. - #4079
Conversation

This also raises a question: does anyone know why scatter still has the undocumented "verts" kwarg? We should either remove it, with deprecation if necessary, or include it in the docstring. |

I am fine with removing it as it looks like it is one more way to specify the marker shape. Probably do need deprecation cycle though.

I also tried to clean up some of the scatter code and documentation, together with related documentation in collections. I added a test.

Issue fixed on matplotlib master matplotlib/matplotlib#4079
There was a problem hiding this comment.
Coming in late to the discussion but I have just spent a few minutes trying to determine what I did wrong on my scatter graphs...
I thought c stood as an acronym for color as fc stands for facecolor etcetera... however this does not apply here, specifying color='green' instead of c='green' means you set the edge-colour to green instead of the face-colour...
Should I open an issue/PR about this? Or can people live with this inconsistency?

As far as I understand it, 'c' should be an alias for 'color'. Furthermore,
'color' should specify both edge and face colors, unless explicitly
overriden by 'facecolor' and such.

This is a confusing mess for historical reasons. It looks like there might be a need for "facecolors=None" in the arg list, along with "edgecolors=None". I suspect I had a reason for not including this in the PR, but I don't remember; maybe it is worth a try.
