Gauge title according to value


I have a PV installation which I want to visualize using grafana.
However, I have a db field which is positive or negative depending if I produce and sell current or if I buy it.
Now I am using a gauge to show it, but is it possible to change the gauge title depending on the value (positive/negative)?
Or is there a better option to visualize this?
Best regards and thanks in advance,

no one? :frowning:
