Fast animation of larger heatmaps

Dash Python
1

Hi,

I am trying to generate an animated heatmap, ideally 10 fps or more. The problem is that the heatmaps are around 1000x1000 pixels. I am currently using a dcc.Interval component and a go.Heatmap. I am updating the figure at every interval. Sadly, this is not fast enough for bigger heatmaps. What would be the best route for me to increase the animation speed of the heatmap?

Thanks!

Hey @jcs welcome to the forums.

how are you updating the heatmap, clientside callbacks?

Out of curiosity: What is the use case for this?

Hi @AIMPED
No, I am currently using an @app.callback to regenerate the figure.
This will hopefully be used to visualize radar data.
