Example 4.2 ANOM p Charts with Angled Axis Labels

[See ANMPEX1 in the SAS/QC Sample Library]Consider the example described in the section Creating ANOM Charts for Proportions from Group Counts. In the example, the option TURNHLABELS was used to vertically display the horizontal axis labels. You can also use an AXIS statement to create an angled display of the horizontal or vertical axis labels. The following statements create the p CHART shown in Output 4.2.1:

title 'Analysis of C-Sections';
proc anom data=Csection;
   pchart Csections*ID / groupn   = Total
                         nolegend
                         haxis    = axis1;
   axis1 value     = (a=-45 h=2.0pct);
   label Csections = 'Proportion of Cesarean Sections';
run;

The angle is specified with the a= option in the AXIS1 statement. Valid angle values are between -90 and 90. The height of the labels is specified with the h= option in the AXIS1 statement. See Axis and Axis Label Options.
