Hi,
I just noticed that when we use the legend to enable/disable a series in an item chart with custom marker, there's a display bug.
This is taken from the example provided in your doc - it happens if you click twice on "Male" in the legend to hide/show the series :

Is this a known bug and is there a workaround?
