Multiple tuning windows ("strip charts") for early flight test

Hello all, with my own bespoke VTOL drone design, I need to do flight test to confirm stability and control as I expand the envelope through transition to wingborne. As a manned aircraft flight test guy, I know how to do this, but need strip charts of key parameters eg attitude rates and control surface positions.

The ‘tuning’ window is great, but there is only one. A post from 2020 suggests there is no way to have multiple ‘tuning’ windows open and I’ve searched high and low.

Anyone know how to / ifyou can have multiple ‘tuning windows’ or otherwise set up strip charts for key parameters in flight?

Any help much appreciated!

(PS - Quickview just shows digital data so not really equivalent or what’s needed)

Can you post an example? Do you mean that you want to see the values split out onto their own graphs?

Hi Joshua this is what I mean:

Mission Planner doesn’t really support this, but you can get exactly what you want using MAVProxy and the graph module.

First, you’ll need to install MAVProxy. If you still want to use Mission Planner as the primary connection to the vehicle, you can mirror the MAVLink connection by pressing Ctrl-F and selecting Mavlink in the window that shows up:

Then set up a TCP or UDP mirror like this:

Start MAVProxy and execute:

link add udpout:localhost:14555
module load graph
graph VFR_HUD.alt
graph AHRS2.roll

To see what messages are available to graph, use that same Ctrl-F shortcut from Mission Planner and select MAVLink Inspector (2nd column toward the top). Explore the tree:

You can also do basic arithmetic operations on graphed values. For example, graph VFR_HUD.alt*3.28084 would convert meters to feet.

To get multiple values on the same graph, separate them by spaces like so:

graph AHRS2.roll AHRS2.pitch
graph PID_TUNING.achieved PID_TUNING.desired
