I was able to make a SPC chart by creating variables and then plotting them in a chart using reference lines. The variables I made were for the Average and Standard Deviation (vAvg and vStDev). I then created reference lines in my chart (first line =vAvg, second line = vAvg + vStDev, third line = vAvg + 2*vStDev, etc...). The only thing to watch out for is to be sure that you choose the reference line to be displayed on "Location" of "Primary Y".
I hope this helps.
