I'm tinkering with your example a little bit, but clicking on the legend
items doesn't seem to do anything whether it contains the offending
clipPath snippet or not. What version of matplotlib are you using?
What browser (and version) are you using to interact with the SVG? Can
you attach the SVG file (maybe in both working and broken states), so I
can tinker with it? You may want to try moving the "<defs>" containing
the clipPath up a level, so it is a peer with the histogram rectangles.
That's just a stab in the dark. If that turns out that makes the
difference, that should be an easy enough fix within matplotlib.
Cheers,
Mike

Hi,
I'm trying to create an SVG figure that will show or hide the bars of
a histogram when clicking on the element in the legend. I got to the
point where it almost works...
I'm including the script so that others can play with it, but from
what I understand, the problem is that the first histogram patch
definition includes a clipping path definition
<defs>
<clipPath id="p7ff5b81e1d">
<rect height="345.6" width="446.4" x="72.0" y="43.2" />
</clipPath>
</defs>
that is referenced by all other histogram patches. When setting the
visibility attribute of the first patch to "hidden" , it hides all
patches.
If I remove this clipping path entirely (by hand), the interactive
components work as expected.
This is my first foray in SVG so my approach is probably naive, but
I'd welcome suggestions to make this work. Having one clippath per
histogram item would simplify things, but I don't know the internals
of matplotlib well enough to do this elegantly.
Thanks,
David
