I have several dozen CDS’s stored in a list, and each CDS is for a separate glyph on my plot (I don’t want to use Multiline because then I can’t have circle glyph and line glyph as part of my combined legend). I can successfully set a tap tool callback for each item in the list as I iterate through the list like this:
However, when it comes time to actually use the tap_callback function, I don’t know how to reference which CDS in my list I am trying to access to get the selected indices from the tap. All the examples I can find only have one ColumnDataSource in the code, which is then easy to reference and access by index in the callback (with source.indices, for example). How do I know which of my CDS’s in the list cds_availability has been selected with the tap? In other words, in this example, how do I reference the correct selected source to get the indices of that selected source?
