I have a multiple line chart that uses both vertical axises where the range changes regularly for each series. I set both axises to the desired setting so that one line (the one that used the left axis) is always on top of the other (right axis). But as soon as I change the source data, the lines go back to overlapping. Is there a way to have one line chart always be on top of the other so that they aren't touching regardless of ranges? I thought of having multiple plot areas within one chart but i didn't see any options for that. thanks in advance.
