Added a checkbox for (re-)generating auto-legend

anykraus · anykraus · commit 63894f959aad · 2014-04-22T14:19:10.000+02:00
Checkbox added that controls if an automatic legend is re-generated, or generated for the first time.
This checkbox defaults to False, as it generates a simple legend when set to True, see matplotlib.pyplot.legend(), which clobbers any carefully handcrafted legend.
