Issue with Custom Needle Image Rotation on Speedometer Gauge
Hi everyone,
I am trying to customize a standard LabVIEW Speedometer/Gauge control by replacing the default needle with a custom image, but I'm running into a rotation logic issue.
The Problem:
When I import my custom image (originally 12x150 px) onto the needle part in the Control Editor, the needle moves along the gauge arc but stays vertically static—it doesn’t rotate to point at the numbers.

What I've Tried:
I followed the common advice of placing the needle on a transparent square canvas (300x300 px) with the base of the needle positioned at the exact center (150, 150) to create a pivot point.

I want the custom image to behave like a standard vector needle where the base stays fixed at the gauge center and the tip rotates to indicate the values.
Any advice or example .ctl files would be greatly appreciated!
