Rotating pointer on knob issue

[DanH]

I have two pointers in my knob LAF. I want one of them to move to a modulation value (references elsewhere in the script) and one to point at the knob value. However the two g.rotate functions add together to make the bottom one completely out of scale / range.

How can I separate them from each other in the script?!

	// White Pointer
	
	g.setColour(Colours.white);
	g.rotate(-2.42 + obj.valueNormalized * 2.42 * 2, Rect.getCentre(obj.area));
	g.fillRect(Rect.translated(Rect.withSizeKeepingCentre(obj.area, 1.8, 4.8), 0, -11.7));


	//Blue Pointer modulating
	
	g.setColour(Colours.white);
	g.rotate(-2.42 + modValue * 2.42 * 2, Rect.getCentre(obj.area));
	g.fillRect(Rect.translated(Rect.withSizeKeepingCentre(obj.area, 4, 1.4), 0, -16.8));

@DanH The first time you rotate the canvas you are starting from 0, the second time you are starting from the first rotation. So I think (I'm just guessing) you need to rotate back to 0 before you make your second rotation - or you need to account for the first rotation in the calculation of the second.

Perfect, thanks!
