ext like „km“ or „min“ after each sensor data? I do not want to add „%“ to the whole column.

for example i wanted to return the produce of my solar panels.
let valueLabel = mainStack.addText(${result.value}W);
This is based on the gauge script on this gist.

the "W" is like you want or km or min.

see my full script an example of a forked (edited) version from gauge script m33x
