Here’s a chart with many datasets (note that the legend spills over across two columns):

Issue

Normally, I’m able to click on the legend items to toggle datasets. However, it seems that in this case, clicking on the legend items doesn’t seem to have an effect.

Perhaps it’s due to the high number of datasets? If so, just wanted to share the issue as a possible bug.
