I've searched the web but can't find a concise list of equations or methods
of 2D or even 3D drawings. Everything I find seems to relate to some form of
software CAD package which is no good.

Yes. I want to measure the duty cycle of the injector pulse and display this
as either a bar (like a VU meter) or a rotating dial like a rev counter.
Oh and also have the same for a rev counter.
I could go back to basics and translate the duty cycle into a rotation angle
and do some trigonometry but I don't want to do it the long winded way if
there are easier ways of doing this kind of thing.
