Item analyser, graphical

I’m running on the latest OH3 stable version.
I have a heating regulator running in my rooms.
To get a quick overview I want to have a chart to show the measured temperature and the opening-staete from the valve.
If I put both items in a graph ( Main Ui, clicking on the temperature Item), I can see both lines.
Unfortunately the temp has a range from ~15 + ~25 degress and the valve state from 0-100%.
Is there a way to have two scales? Maybe left side for temp and right side for %.

There is a area in the diagram to change the ranges ( default is auto), but I do not find a way
add a scale for the second value.
