The red triangle menu next to Range Chart or Standard Deviation Chart contains the following options:
Show Average Dispersion
Draws the average range or standard deviation on the chart.
Show Connected Points
Draws lines connecting all of the ranges or standard deviations.
Show Control Limits
Draws lines representing the Upper Control Limit (UCL) and the Lower Control Limit (LCL) and labels those values. For more information about the calculations of the limits used in the Range Chart, see Control Limits for XBar and R Charts. For more information about the calculations of the limits used in the Standard Deviation Chart, see Control Limits for XBar and S Charts.
Show Control Limits Shading
Adds shading between the UCL and LCL.
Show Separators
Draws vertical lines to delineate between the X variables.
Note: You can replace variables in the Range or Standard Deviation Charts in one of two ways: swap existing variables by dragging and dropping a variable from one axis to the other axis; or, click a variable in the Columns panel of the associated data table and drag it onto an axis.
