subforum related to: Canvas
We want to develop a generic graph widget using the Canvas system. The widget shall be usable in all major placement modes, i.e. 1) dialogs, 2) standalone GUI windows, 3) aircraft instruments.
Such a widget would be useful for a whole number of purposes, including:
- FDM/Autopilot tuning
- Plotting internal statistics (system monitor)
- Flight path evaluation (instructor station)
So the graph widget needs to be customizable for different plotting needs. In addition, we want to provide a PropertyPlotter implementation to directly plot properties from the property tree (altitude, speed, FDM/autopilot properties).
