If I use a Gauge with a minValue other than 0 (in my example 4), the Radial seems to always add said minValue to the "value".
In other words: My Gauge has a minValue of 4 and a maxValue of 12. If I now set the value to 4, it shows (and displays in the LCD) the value of 8. I can't get under the value of 8, because if I'd set the value to 0, it is clamped to 4.
If I now set the value to 5, it shows 9. So somewhere you falsely add the minValue to the (already clamped) value
