You would think this would be simple but I've spent an hour trying various things to get is to happen.  I'd like a plot of my target star's measured magnitude against JD.  However, it always displayed as a deviation from its mean, max or min (at least I think that is what it is doing.

Here is my plot:


Here is my measurement showing I do have magnitudes in Source_AMag_T3


Here is my Multi-plot Main:


And here is my Multi-plot Y-data


Could someone please explain what to change to turn the normalization(??) off?
