Live viewer for monitoring scan data in real time #216

Closed canismarko closed 2 weeks ago

canismarko commented 6 months ago

Looking for a way to view the current scan results in real-time in Firefly.

My current strategy is to use the Kafka server that is routing the RunEngine documents.

  1. Create a LiveViewer window as a child class of the RunBrowserDisplay
  2. LiveViewer listens to the kafka topic for new documents
  3. If it sees a primary event, load that scan from tiled and display it.

@Cathyhjj I'm working on the run_browser.py file extensively right now, trying to get those tests to pass so I can work on this liveviewer. Might be easier to wait on implementing some of those advanced pyqtgraph tabs you had planned until I'm done?

Implemented this using a kafka client. It subscribes to the beamline's queueserver kafka server and then fetches new data from Tiled when necessary.

Still some minor imprvomenets, but I'll make those in separate issues.
