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!
