negative minvalue not handled correctly #68
Description
I try to create a thermometer for outside temperature. Any gauge I tried so far (radial and linear) do position needle to lower end of scale even when lower end is -30 degrees Celsius. Example:
Gauge is configured for minValue: -30 and maxValue: 40
Outsidetemperature is currently 0.0 degrees Celsius
Result: needle is positioned at about -30 degrees Celsius on the card (which is the "normal" = 0 starting point of gauges...)
==>I assume gauges cannot handle negative numbers :-(
PS: I used an example config I have found here: https://canvas-gauges.com/documentation/examples/
