Can Plotly Dash animations display buttons and sliders? about dash.jl HOT 6 OPEN

Thanks for reporting!

This should work. Dash.jl and PlotlyJS.jl use the same plotting backend.

What's most likely happening is that PlotlyJS.Plot put the array of PlotlyFrame elements somewhere that JSON3.write does not know about.

We could try to patch

accordingly.

@etpinard Oh thanks for the response. Okay, so is this code that would go into a Dash.jl pull request or something that I can just add to my own code to override the existing dispatch?

Should I try and submit this code change as a PR?

from dash.jl.

Yep, ideally it would go in a Dash.jl pull request. This is a bug we want to fix!

I can submit a PR, no problem. Is there a test case that I should add to try this, or do I not need to add an additional test case. I have not submitted a PR to Dash.jl before, so just want to make sure I do it correctly.

Is there a test case that I should add to try this,

Unfortunately, similar PRs #143 and #166 relied on integration tests to lock down their patches.

If you can get the integration test running on your machine, adding a similar integration test file would be fine.

Otherwise, a new @testset block in test/core.jl would be great.

@etpinard say, as a temporary workaround, can I just write my own Play button and Slider using Dash components? I can compute the frames and save them in a Store, and then load them manually.

I was not sure how to update a frame in a plot though--is that possible? I only have 1 animated trace out and 3 static traces in my plot. If I just update the data in the Plotly Graph Object, then I imagine that is the best way to do it--instead of repainting the whole plot. I can try that as a temporary workaround as I try and get the main issue fixed.
