Update graph zoom from callback

Hello! So I have a dash app that displays data over periods of time. Since there is a slider for the user to reduce or expand the time range observed, which updates all the graphs and maps to the selected range. However, I would like to improve performance by having the callbacks set the x-axis range of the graphs as opposed to re rendering them every time. Is this possible?

You can access the layout by putting the the figure in a State of the callback. The fig is basically a json object, you can go in there, edit what you need from the layout and use that as the output. So if your callback would look something like this…


I do something similar to that to add points to a map so that I’m not re-rendering every time.

Very nice idea. Any tips on what attributes to edit to change the xaxis range shown?
