I am sorry to say that the graphing of PID data is absolutely horrible.
Graphing is worse than launch.
You cannot control the time base.
You cannot control the scale.
It constantly auto ranges the min-max on PIDs confusing the user.
Choosing of PIDs for graphs is akward, but usable.

The graphing is a weak point. The Scale should be a fixed value, and show a longer time scale, otherwise you only see 1-2 seconds worth of graph. It would also be useful if the user could set the scale and time parameter as needed per PID.
