combining telemetry point

[alexhoffenreich]

Is there a plug-in that I could combine values of different telemetry points into a new point?
I.e.:
I drag two telemetry points to the plug-in, then write a function in javascript in the form that combines between them, like:
p => Math.sqrt(p[0] **2 + p[1]**2)
or
p=> p.map(p[0] %2 ==0? "even": "odd")

and the new telemetry point represents the result

If not exactly, is there anything that can provide similar functionality?
