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:
Axis |
Input Data Set |
Variable |
|---|---|---|
Horizontal |
all |
subgroup-variable |
Vertical (median chart) |
DATA= |
process |
Vertical (median chart) |
HISTORY= |
subgroup median variable |
Vertical (median chart) |
TABLE= |
_SUBMED_ |
You can specify distinct labels for the vertical axes of the median and 
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 chart.
For an example, see Example 15.17.
