Line Plot Aesthetics
With the line settings, users can modify the width, type and colour of the lines in the SPC chart. Each line has its own group of settings, listed below.
Additional Target Value
By default, the SPC chart depicts a statistical centerline as set by the chart type. This allows for a comparison of how the process may be changing over time, relative to historical results. However, there are applications where a target value may be appropriate to include as well. This can be set using Additional Target Value in the Alt. Target group, with Show Alt. Target Line turned on. The value is entered as a plotted value; turn on Apply Multiplier to Alt. Target to enter it as a raw proportion or rate instead.
The example below sets an additional target line at 5, and turns on Show Value on Plot for the target and alt. target lines to label them. The additional target line is black by default; its colour, width and type are set in the same group.
