[Feature Request] Hideable/collapsible subplots

[betteridiot]

It is simple enough to hide the trace by clicking on the legend...but the axes and canvas for that subplot still exists. A fun feature (mainly for data exploration) would be able to hide/collapse the subplot until selected. Since I don't really know if you can synchronize plots within different divs, such a feature would allow vertical subplots to expand upwards/downwards when opened, and horizontal subplots to expand left and right when opened. Such actions could allow currently opened plots to be re-centered into the current div.

How? By adding a button in the mode bar?

That's sounds painful to describe as data/layout attributes.

Quite frankly, I believe this feature would best implemented in userland (i.e. not in this library)

I figured the rescaling of the canvas would be a bit much. However, a button or check box next to the subplot legend

plotly.js does not allow per-subplot legends at the moment (see #1668). So, it really isn't obvious to me how this would work w/o confusing long-time users.

Merging this ticket with #1668
