Hi all,
I am hoping to connect/trigger plotly animations to start/stop when an HTML button is clicked (same button will play/pause an independent video). Currently, I have the sample animation working in Plotly Python/I think I need to convert to plotly.js for it to be feasible, but my question is:
- for updatemenu buttons, what event is emitted/triggered when they are clicked? Right now I have a simple play/pause–is it possible to tell when these updatemenu buttons are clicked?
Additionally, am I able to to fast forward the animation programmatically (based on an external slider)? Or if I integrate a slider to the update menu, what event is triggered there? I briefly tried Dash, but seems to run into the same issue.
Thanks!
Peter

Hello @prehani,
It sounds like maybe you could link the animation with a slider that could get updated at n\_intervals in Dash. Then perform a callback the steps it however many frames.
For the updatemenu, in Dash this is possible by having multiple inputs to 1 output.
Plotly and Dash use React components, and are a little tricky to get the hang of when moving from straight javascript. Plotly.js has its on set of event listeners and such.

Hi Prehani, did you ever get to the bottom of your issue?
I am having the exact problem right now, where I want an animation and a separate video to be triggered by the same butten/event.

The last example seems to me to be what you are looking for.
