hi,
I want to overplot N curves calling the plot(X) function N times.
I also would like to have a way to which curve has been drawn first and so on.
If N would en small and constant, I could simply call color_cycle with

I'm use to compile the mpl git tree but I get an error with the current one:

Hi,
It looks like the matplotlib-py3 branch is worknig well both with
python2.X and python3.X.
Is there a plan to merge the changes from matplotlib-py3 into the
