markeredgecolor (mec) in the plot function not working?

Community matplotlib-users

Dear all,
I use matplotlib 1.1.0.
import matplotlib.pyplot as plt
plt.plot(np.arange(10),‘ro’,mec=‘none’)
when I use plt.show(),
there is only blank frame with axis not no points.
but plt.plot(np.arange(10),‘ro’) will give good plot with read filled circles and black edges.
plt.scatter(np.arange(10),np.arange(10),c=‘r’,marker=‘o’,edgecolor=‘none’) is working fine.
but I really think plt.plot is a very good and easy function if you don’t make complex scatter points. and the circles look much nicer than that produced by plt.scatter (thought I don’t know why
as they use the same symble…)
does anyone else have found the same ?
thanks to all,
Chao

This works for me with GTKAgg backend. If this is still a problem for you, which backend are you using?

Dear Ben,

I tried again with dev version and GTKAgg backend it works.

In [3]: mat.version
Out[3]: ‘1.2.x’

In [4]: mat.get_backend()
Out[4]: ‘GTKAgg’
