Rangefinder data on the Telemetry Plot screen does not appear

[joe-stroup]

I recently added a CubePilot Here Flow optical flow sensor to my copter.

To help monitor the lidar rangefinder output, I thought I'd plot that on the Yaapu telemetry plotting page.

Unfortunately, no data appears:

Checking on Mission Planner - this data is available:

I tried other data - and most but not all of them worked for me. I also repeated the "discover sensors" procedure - just in case the rangefinder data needed to be added. I also tried plotting the Sonar data - just to make sure it wasn't using that data.

The rangefinder parameter names have changed a few revisions ago - so that it now easily supports multiple rangefinders. The rangefinder parameter names now have a "number" following them to identify which rangefinder. (They did the same thing with the camera parameter names.) As a guess, I wonder if Yaapu uses the old parameter names without the number identifiers at the end.

If it's possible to get this data on the Yaapu telemetry plotting screen, I would appreciate it.

Is there something I need to do to make it appear?
