Multiple windows

Sorry for the noob question but is it possible to have multiple browser windows that can share data (like a time sync variable)? Use case is data review application which has map and multiple graph windows displayed on multi-screen debriefing room. Screen real estate won’t work with a single window.

My reading indicates this isn’t possible.


The best way to do this would be to write your data to a file and have your callbacks always read the data from the file. You can periodically update your UI (re-read your data file) on an open app by using the dcc.Interval component or by updating the data on page load by setting app.layout to be a function. In both cases, see this chapter in the docs:

Yes that works! Just experimenting on latency and interval.

Thanks for quick response and congratulations on a great project!
