I'm plotting power generation values in an SPCChart but I'd also like to lay over it a second data series showing ambient temperature design power values for comparison. Right now I'm passing the second data series in as a control limit but it suffers in appearance. Setting it up as a second value column causes the chart to fail. I need to use an SPC Chart because the users want to enter data point comments.
One solution might be to use an iChart and handle the comments in a separate process. I'd lose the red comment flags but that would be a small price to pay.
We're running 12.0.4.
Thanks for the help!
