[Feature Request] - Duty Cycle

Can we have a duty cycle chart, possibly on the temperature page?

I'm thinking some sort of graph that moves at the same time as the temp chart, showing whether or not the different heaters (Hotends, heated bed, etc.) are on or off, and calculate a duty cycle percentage.

Could possibly be incorporated with the feed rate, so that if the hotend hits 100% duty cycle during a print (but not initial warmup), the feed rate is reduced until the duty cycle is below a specified threshold.
