MRCHART Statement: SHEWHART Procedure
Axis Labels
You can specify axis labels by assigning labels to particular variables in the input data set, as summarized in the following table:

You can specify distinct labels for the vertical axes of the median and R charts by breaking the vertical axis into two parts with a split character. Specify the split character with the SPLIT= option. The first part labels the vertical axis of the median chart, and the second part labels the vertical axis of the R chart.
For an example, see Example 17.17.
