How to raise Dew Point line

is there a way to raise the Dew point line with out lowering the temperature range. The reason I ask is when the Dew point drops below the minimum temperature range it spikes to the top of the graph.


the best thing is to lower the minimum temperature scale range for the outdoor temperature…as the dew point uses the same scale
in the graph setup

yeah I have found that out but isnt there a way to move the line like the Baro line.
