[matplotlib-devel] Adding interactivity to an histogram in SVG

[David H. <dav...@gm...>]

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
