Bram,
Although I don't quite see the point, I would simply suggest that you
re-call ax.legend(ncol=2) , that would delete the previous and redraw a
new one
from matplotlib doc: When the legend command is called, a new legend instance
is created and old ones are removed from the axes.

Subject: Re: [Matplotlib-users] set ncol for legend
I realize that I have not been clear enough.
I have already created a legend instance in my_own_plot_function,
for example, a legend with one column by default:
fig = plt.figure()
ax = fig.add_subplot(111)
my_own_plot_function(ax, data) # gives, for example, one column
legend by default
So ax is an axes instance containing the legend.
Incidentally, after inspecting the automatically created plots, I
want a particular figure to have a two column legend. I would like
to do this without adding an extra kwarg for the number of columns
to my_own_plot_function. It should be possible to do something like
this:
legend = ax.get_legend()
legend.set_ncol(2) # something like this
Once again, thanks for any help!
Bram

plotN = plot.plot(X,Y,label='N')
legend = plt.legend(ncol=2)
should work...
so, for your "own_plot_function", you have to return the legend
and set it accordingly...

Hi,
I want to update the number of columns in my legend. How should I
do that?
I'm looking for something like:
fig = plt.figure()
ax = fig.add_subplot(111)
my_own_plot_function(ax, data) # gives, for example, one column
legend by default
legend = ax.get_legend()
legend.set_ncol(2) # something like this
However, ncol is not in the legend.properties() list for
properties to be set through legend.set.
Thanks for any help,
Bram
