I used an Excel spreadsheet to generate some pressure - temperature curves. I then created an ODBC dataset to plot the curves on an xy plot in ProcessBook. I am trying to figure out how to plot a pressure - temperature point, taken from the PI server, on the same xy plot.
I've tried creating a line/polyline to simulate the curve over the xy plot and then just plotting the p-t point, but everytime the xy plot gets moved, my curves are no longer accurate.
