Axis Labels

You can specify axis labels by assigning labels to particular variables in the input data set, as summarized in the following table:

For example, the following sets of statements specify the label EWMA of Clip Gaps for the vertical axis and the label Day for the horizontal axis of the EWMA chart:

proc macontrol data=Clips1;
   ewmachart Gap*Day / weight=0.3;
   label Gap = 'EWMA of Clip Gaps';
   label Day = 'Day';
run;

proc macontrol history=Cliphist;
   ewmachart Gap*Day / weight=0.3;
   label Gapx = 'EWMA of Clip Gaps';
   label Day  = 'Day';
run;

proc macontrol table=Cliptab;
   ewmachart Gap*Day;
   label _EWMA_  = 'EWMA of Clip Gaps';
   label Day     = 'Day';
run;

In this example, the label assignments are in effect only for the duration of the procedure step, and they temporarily override any permanent labels associated with the variables.
