Interpolation / linear or polynomial. Help needed.

Hi all!

I'm working on a project with a Reed Sensor to mesure the speed of a turning wheel sending On/Off values to MAX. I have accomplished to get RPM and Average Speed.

My problem is that I need a constant interpolation of these values, because all I'm getting is points every time the sensor goes on. (See uploaded .png)

In other words: I need to conect every new (RPM or Av.Speed) point with the last one linear or polynomial.

Thanks in advance for your help.

You don’t say how you’re doing it now (what you have tried so far), but how about the ‘lineto’ message to jit.lcd?

Thanks for your answer.

I`m not interested in drawing this values. All I need are interpolated linear values from non-linear ones.

That means that if for example that if I become a value of 10RPM and later a value of 20RPM I want to go from 10 to 20 (like 10, 11, 12,…,20), later 12RPM (20, 19, 18,…12) and so on.
