Current implementation will not meet end user objectives
Since both tags for steam pressure have units PSI (high and low pressure) they will have same Y-axis
Just wondering if parallel axis chart is the right one for your use case instead of Multi Y axis.
Parallel axis is a different type of chart and not intended to solve the same problem as time-series chart Y axis. So this will not be a solution.
This feature is really needed, I have heard this from TEPCO, OSEONG, TSIN TAO and Exelon. The user needs ability to independently select the y- axis settings for each tag.
