The hard part is getting a good temperature probe into the bean mass on the Behmor. It's just not set up for it.

Real time graph of what?
Graphing temperature from a PID controlled system totally misses the point. A PID will force the beans to follow the curve you've defined. I think graphing the duty cycle output from the PID would be far more interesting.

Or graphing a non-PID roast, then programming a PID to repeat it.

But graphing a PID roast is as interesting as tracing a line. All the interesting stuff with a PID roast comes before you start roasting.
