Matplotlib markers disappear when edgecolor = 'none'
markers, matplotlib, python, python-2.7
Solution
I think this is a bug that was fixed a few months ago: https://github.com/matplotlib/matplotlib/pull/598
Regardless of how large you make the markers or if you use `marker='o'` instead of `'.'`, they'll be invisible if you use `markeredgecolor='none'`.
As a workaround, you can just set the edge colors to the same as the face colors.
Problem
I'm trying to make a scatter plot of some PCA data. I do some pretty typical code: ``` plt.plot(pca[:,0], pca[:,1], '.',ms=3, markerfacecolor = self.colors[k], markeredgecolor = 'none') ``` I want it to show just the marker face color with no outline. The problem is that the markers disappear completely when markeredgecolor = 'none'. When I set markerfacecolor='none' or to a color and remove markeredgecolor, it works like expected. I just updated matplotlib, numpy, etc. to the newest versions, running on Python 2.7. Thanks for your help.
