Overview

The PCHART statement creates ANOM charts for group (treatment level) proportions, also referred to as ANOM charts.

You can use options in the PCHART statement to

• compute decision limits from the data based on specified parameters, such as the significance level ()
• tabulate group sample sizes, group proportions, decision limits, and other information
• save decision limits in an output data set
• save group sample sizes and group proportions 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 on the same chart
• 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 PCHART statement:

• Traditional graphics are produced by default.
• ODS Graphics output (supported on an experimental basis in SAS 9.2) is produced when you specify the ODS GRAPHICS statement prior to the PROC ANOM statement.
