Gauge with negative values

[Jonas Karlsson]

Hello!

Having some problems with a gauge that has negative values. My range is from -70 to 70.
Is it possible to set the bar to start from 0 or the middle of the gauge?
With the code below the bar goes from -70  or left side of the gauge to the value that is set.

Hello Jonas,

Thank you for writing.

From what I understand you want your bar indicator to start from 0 and increase to the right for positive values and to the left for negative values. Is that correct?

Currently our radial gauges support negative values in the sense that the radial indicators can increase from right to left only from left to right. The linear gauges however support this behavior.

Kind regards,
