Text Counter Connected to Layers Z-Rotation
I’m trying to build an analog meter with a digital text readout. Basically, I need the the source text to read out the rotational value of another layer. As you can see in the image, I want it to be able to read 0 when the needle is at 0, 1 when the needle is at 1 and so on and so forth.
All help is much appreciated!

This might work:
minRot = -75;
maxRot = 75;
minValue = 0;
maxValue = 6;
rot = thisComp.layer("Shape Layer 3").transform.zRotation;
linear(rot, minRot, maxRot, minValue, maxValue);Xavier

Genius, genius, genius! One last question. What can I add to the code to keep the text to only two decimal points?

***If you want exactly 2 decimals, you can use:
… // same beginning
x = linear(rot, minRot, maxRot, minValue, maxValue);
x.toFixed(2);***And if you want at most 2 decimals:
…
x = linear(rot, minRot, maxRot, minValue, maxValue);
Math.floor(x*100)/100;Xavier
