Overview: XCHART Statement :: SAS/QC(R) 12.1 User's Guide

The XCHART statement creates an ANOM chart for group (treatment level) means of response values. You can use options in the XCHART statement to

compute decision limits from the data based on specified parameters, such as the significance level ( $\alpha$ )
tabulate group sample sizes, group means, decision limits, and other information
save decision limits in an output data set
save group sample sizes and group means in an output data set
read decision limits and decision limit parameters from a data set
display distinct sets of decision limits for different sets of groups
add block legends and symbol markers to identify special groups
superimpose stars at points to represent related multivariate factors
clip extreme points to make the chart more readable
display vertical and horizontal reference lines
control axis values and labels
control layout and appearance of the chart

You have two alternatives for producing ANOM charts with the XCHART statement:

ODS Graphics output is produced if ODS Graphics is enabled, for example by specifying the ODS GRAPHICS ON statement prior to the PROC statement.
Otherwise, traditional graphics are produced if SAS/GRAPH^®is licensed.

See Chapter 3: SAS/QC Graphics, for more information about producing these different kinds of graphs.
