Real time event when dragging or zooming the plot

plotly.js
1

Hello,
I would like to hook data in my webpage to what is displayed on the graph. I am currently using the ‘plotly_relayout’ event but this event only fires at the end of the dragging action, while I want to do some real time feedback.Is there such an event available?
The current alternative I am looking at is to hook on event on mousemove and check the changes of the transform attribute of the .plot element, and then translate these values into the data domain.
Thanks,
Daniel

Not at the moment. I’d recommend trying to bind an event handler to the graph div itself. I can’t guarantee this will perform well though.

Hey @daniel @etienne did you find a good solution for this? Would really appreciate any help, as I am stuck on this for long. Could you also share a code snippet of what you ended up doing?
Thanks!

Did you find any solution?

Binding the mousemove event to the graph div only fires when I move the mouse without dragging. Even adding graphDiv.ondragstart = () => false; didn’t help here.

I need to “link” two plots.

I think I had something similar, but I used Dash and Python…
