In the extra components you can fill in a minimum and a maximum value, in the gauge and in level, but these are constants. I would like to fill in variables like an input with a formula. Is that possible?
Min and Max are constants. That’s true. As a work around you could create an extra input channel of the Calculated type. And set a formula to calculate some kind of relational value.
i would like the right picture, but the colors of the ring changing with time regarding a variable bandwidth.
The right picture uses a background found somewhere in the internet. A display over a gauge is a dynamic text component.
