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 (box chart) |
DATA= |
process |
Vertical (box chart) |
HISTORY= |
subgroup mean variable |
Vertical (box chart) |
TABLE= |
_SUBX_ |
Note that if you specify the CONTROLSTAT=MEDIAN option, you should assign the label to the subgroup median variable in a HISTORY= data set or to the variable _SUBMED_ in an TABLE= data set.
If you specify the TRENDVAR= option, you can provide distinct labels for the vertical axes of the box and trend 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 box chart, and the second part labels the vertical axis of the trend chart.
For an example, see Labeling Axes.
