I notice a somewhat weird looking gauge when using "Fill gauge from centre" together with a non-symmetric differential range.
The new gauge property "Fill gauge from centre" seems to assume a symmetric differential range and scaling.
But this often is not the case.
I would like to suggest a property variable to be added (for example "centre" in between the min/max range).
So that we can define where the "start filling" point is within the range.
Because the way it is displayed now in the picture below, makes no sense.
That way the property "Fill gauge from centre" will display correctly, even when using a non-symmetric range.
Also a property could be added for a scaling offset. In case you would like to have "0" in the middle of the gauge when using a non-symmetric differential range. For example: a scaling offset of -3000 would do this.
