Two TapTool questions

I have two plots that do not share the data source, but both understand the labels from the categorical x_range of plot one. When tapping an object in the first plot I want the second graph to show detail for that name.

Firstly, what’s the best way to organise communication between plot one and two? Secondly, tapping on an object greys out other objects in the plot. Is there a flag to tell TapTool not to grey out the other glyphs?

I also noticed that only one TapTool can be active for a given x value. How can I have more than one TapTool that would distinguish between the multiple series plotted against a given x value? I understand at the moment one can only get an x coordinate (or index), not the name of the series that was tapped, is that correct?

I would suggest that you want a CustomJS callback for your TapTool, that is configured with both data sources in the "args" dict for the callback.

Regarding the visual appearance of selections, those are set by policy, there is some information about that here:

  http://bokeh.pydata.org/en/latest/docs/user_guide/styling.html#selected-and-unselected-glyphs

I think if you want nothing to look different, you could do:

  renderer.nonselection_glyph = renderer.glyph

or possibly (untested)

  renderer.nonselection_glyph = None
  
Thanks,

I'm not sure that's true? I would not expect problems with multiple tap tools, each configured for a different set of renderers. Do you have any actual code you can share of what you've tried?

Thanks,

Bryan

Fantastic, thank you. The CustomJS callback works like a charm.

Also true as far as the nonselection_glyph is concerned. I am back in control!

You are correct, my oversight. The TapTool takes a list of renderers, not just one renderer. It’s when you define several TapTools you get mutually exclusive TapTool icons in the toolbar…
