How to register JS callbacks on stream updates

Community Support
1

Hi,

I am willing to update Glyphs (i.e. lines) whenever data source change occurs (and chart is updated) - I am using data streaming. My JS code works fine when I bind it to some event (like fig.x_range.callback).
The problem is that I want it to update each new data is appended and I can’t find any relevant JS callback.

Sound unreasonable to me to use Python callbacks for frontend only constant updates.

Thanks

Meir,

I'm not sure there is one at the moment. It would be fairly straightforward to add. Can you make a GitHub feature request issue for this? I can try to take a look at soon.

Thanks,

Bryan
