linked crosshair

Hello,

To ease comparison between two graph, how could I obtain a linked
crosshair in between two or more different plots as for example this one:
http://bokeh.pydata.org/en/latest/docs/user_guide/interaction.html#linked-panning

If mouse pointer on first graph, a full crosshair would appear on this graph and the second graph,
while only the vertical part of the crosshair would appear in the last one (ie the one corresponding to the shared axis).
If mouse pointer on last graph, a full crosshair would appear on this graph but only the vertical
one (shared dimension) on the other two.

Any hints would be helpful.

David

PS: Many many thanks for Bokeh !

Hi David,

You haven't missed anything, this is still an open feature request:

  https://github.com/bokeh/bokeh/issues/3799

It's conceivable that a solution could be cobbled together with hover tool callbacks and some of the private JavaScript API for CrosshairToolView, but it would not be completely trivial to do. Perhaps you could chime in on the issue above with some suggestions for how you would like to be able to "spell" linking two crosshairs together. I find concrete proposals help focus efforts on features like that.
