Figure with large data set and ScatterGL rendering empty graphs

Dash Python
1

Hi Dash Community:

Can you please suggest the latest best approach to render large data set?

  • For timeseries, I think the tradingview’s lightweight chart wrapped into Dash is pretty cool.
  • However, it doesn’t support scatter chart ( I don’t think the original version supports it neither ). I tried Scattergl traces in Python. For a long time, I saw problems of the graphs being rendered as empty in a random fashion when using the ScatterGL. Is this true for you guys as well? Thanks.

Personally I use ScatterGL and I’ve never had an issues with it being rendered as empty. Sounds like either a bug in your code or a bug in plotly/dash. If you can drop an standalone example code which replicates your issue then people should be able to help you further. Cheers

Hi,

I guess the reason may be the limit of of GL contexts that it can display at once. See this issue. Hope it helps.
