I am creating a control chart with three different phases and my control chart points are not lining up with the limits (sample = denominator). It appears the points are sitting on the middle of the limits instead of the middle. I have looked through all the axis options and cannot find a solution. Also, the issue is only occurring in the first phase of my chart (the "2" phase). I removed the phases and it worked just fine. Any help would be great. My JMP script is below.
