Bad performance over time, up to a crash

Hi everyone

I’m using plotly to display a real-time heatmap data, as seen here:

At the bottom of the page you can see the frames per second i get.
After a few minutes you can see the framerate getting lower and lower.

After about 10-20 minutes I get to 1-5 fps (started with about 20 fps)
Waiting for enough time and i get a crash in the tab that displays the data. Chrome displays an out of memory error.

This has been tested using Chrome (57.0.2987.133) and Microsoft Edge (38.14393.1066.0) browsers on a Win 10 machine.

Any help will be appreciated.


Thanks for the report. We’ll try replicate the problem.

Etienne, do you have an update on this issue?
