Display PID Power Setpoint as Graph

[Quas7]

Hi,

this is a feature request and might be easy to implement for someone familiar with the codebase of this very nice plugin.

For PID tuning of hotends it is favorable to see the PID setpoint (=result of PID controler). It has a value of 0...255 for hotend and bed and in Marlin M105 output it is marked with "@:" and "B@:"

Recv: ok T:209.02 /208.00 B:59.90 /60.00 @:26 B@:127

The issue is also open on Octoprint itself here: https://github.com/foosel/OctoPrint/issues/647

Maybe, someone is interessted as well in this feature. Most other 3D printer servers have this feature.

I too am interested in this feature. Just came over to Octoprint from Repetier Host and displaying the PWM is a great way to visually troubleshoot temperature regulation problems and the impact your filament fan has on the hot end. I tried looking at the code to see if I could make sense of it but being an embedded C developer I could not figure it out at all.
