Re: [Matplotlib-users] Setting a user defined color for each marker of a Line2D

[Thomas C. <tca...@gm...>]

If you want each marker to be a different color you have to use scatter.
You can pass scatter a sequence of colors (see
http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.scatter) so you
don't have to go through making a custom colormap.
