Cannot set min prop other than 0

Cannot set min prop to other than 0.

Step to reproduce: Just change min prop to -10 or 20, then the gauge will error

I am having the same issue, min values of anything other than 0 give very odd looking gauges. The ticks are all over the place. Would be really nice to have a fix for this.

Thank you

Apparently the bug is in getAngle(value) method. As far as I can tell, changing:

-        return ((value * totalAngle) / totalValue) + startAngle
+        return (((value - min) * totalAngle) / totalValue) + startAngle

solves the issue.
