Goyo,
Again I thank you for taking time to look into this. You are correct that
there are separate functions for setting the marker properties vs the line
properties. However, I have tried your solution, and it does not work. Given
the following code:
import pylab
pylab.plot(pylab.linspace(0,1,100),label='Test',marker='o',ls='')
pylab.plot(pylab.linspace(0,1,100),label='Test2',marker='o',ls='-')
leg=pylab.legend(loc='best')
line=leg.get_lines()
line[0].set_markerfacecolor('black')
line[1].set_markerfacecolor('black')
pylab.draw()
I still do not get black markers. Furthermore, if you try to make a new legend
with the result of leg.get_lines(), you will get lines without markers, which
leads me to the conclusion I stated in my previous email (which you did not
copy)

Thanks,
