I’ve been testing and comparing the capabilities of Curve NdOverlay containers and Curve Overlay containers. Specifically, I’d like these two functionalities:
-
Apply a tap action on a curve to select it.
-
Create an aggregated legend entry that can be clicked on to set/unset the curve transparency (the usual behavior with Holoviews/bokeh legend items).
With a Curve NdOverlay I’m achieving #1, but I’ve been unable to have the legend entry be anything other than one entry for each curve in the NdOverlay container. With a Curve Overlay, it’s the opposite: I can easily produce an aggregated legend entry, but I can’t achieve #1.
This contrast was touched on in a thread on StackOverflow over 4 years ago, but there the focus was on achieving #2. The person who posted the original message only brought up #1 at the end.
I’ve tried a number of things and at this point I’m almost resigned to not being able to have both of those capabilities. I could add code samples, but I figured I’d first post at a conceptual level and see if anyone recognizes this need, and a solution. Thanks!
I’m using the latest versions of all holoviz packages, specifically holoviews 1.20.2 and bokeh 3.7.2. I get the same behavior with older versions of holoviews (1.20.0) and bokeh (3.3.4).
