"isolate" legend toggle mode

[leeoniya]

would be good to have a legend mode where clicking a series toggles off all other series (isolating the clicked one).

cc @oscgonfer,

this is now implemented. by default isolate mode is behind Ctrl + click, but you can make it the default mode by setting opts.legend.isolate: true.

Boom 💥

Thanks for this.
On a side note: I noticed that if I make two subplots with opts.sync.setSeries: true, when I isolate the first series of subplot 1, the first series of subplot 2 is also isolated. I assume this is intended behaviour?

[leeoniya]

yes, this is expected behavior. sync simply emits the same mouse events across all charts in the group.
