Hey all,
I want to create a plot that will will have clickable elements that do some active thing. My interest is in plotting a scatter plot of certain features from a set of waveforms that, when individual elements are clicked, will plot a source waveform from that selected feature in either another window or a secondary place of some sort.
I believe Python’s Bokeh library has a similar capability in the form of a callback function that you can pass to your plot call. Is there something similar in any of the Julia plotting libraries?
Thanks.

Have you checked out
[Interact.jl](https://github.com/JuliaGizmos/Interact.jl) + [Plots.jl](https://github.com/JuliaPlots/Plots.jl)
or
[PlotlyJS.jl](https://github.com/JuliaPlots/PlotlyJS.jl) + [Dash.jl](https://github.com/plotly/dash.jl)?
The latter is probably more similar to Python’s Bokeh.

Thanks for the suggestions.
I don’t think Interact + Plots is what I’m looking for, but the PlotlyJS + Dash option might be.
