Possible Feature Request: More native hover interactions?


I have been playing around with “plotly_hover”/“plotly_unhover” to try to achieve some interactions commonly found in other graphing tools.

Here’s what I’ve been able to make so far:

  1. Heatmap (will change color on hover, can be combined with “plotly_click” to simulate buttons)

  2. Scatterplot (will show a marker when hovered, can be a nice visual cue)

However, the biggest challenge is performance, because my approach is limited to making the graph redraw/restyle the data which doesn’t scale well with larger datasets.

I was wondering if these hover features are planned to be supported in the future, or if there are any suggestions to how I can make my current implementations perform better?

Thanks a lot!
