SPC_CHART is a web-interface trend option to create Statistical Process Control (SPC) style charts for Controlled Variables (CVs). When SPC_CHARTS=0, there are no additional limits placed on the trend. As SPC_CHARTS is increased by 1, there are additional ranges added to the CV plots. With a level of 1, new lines at +/- 3 SPHI-SPLO are added to the plot as red upper and lower control limits. With a level of 2, new lines at +/- 2 SPHI-SPLO are added to the plot as yellow upper and lower control limits. With a level of 1, new lines at +/- 1 SPHI-SPLO are added to the plot as green upper and lower control limits. Each level adds an additional two lines.
