Remove the legend on a matplotlib figure
To add a legend to a matplotlib plot, one simply runs legend().
How to remove a legend from a plot?
(The closest I came to this is to run legend([]) in order to empty the legend from data. But that leaves an ugly white rectangle in the upper right corner.)
Answer
As of matplotlib v1.4.0rc4, a remove method has been added to the legend object.
Usage:
ax.get_legend().remove()
or
legend = ax.legend(...)
...
legend.remove()
See here for the commit where this was introduced.
