Auto Range Y Axis in Power Chart

I have the power chart shown below and would like to be able to automatically adjust the y axis range if I deselect certain tags. For instance, supply temp, return temp and DP are all relatively low compared to flow and energy rate, how can I get the power chart to auto adjust the range to show the other closer if i deselect flow and energy rate.

@alec did you happen to find a solution to this? I'm currently looking to do the same thing.

I did not. It was low priority so I moved on to other stuff and actually forgot about it. So if you do find a solution I'd love to see it.
