The GCHART Procedure

Example 6: Generating Error Bars in a Horizontal Bar Chart

Procedure features:
HBAR statement options:
CLM=
COUTLINE=
ERRORBAR=
FREQLABEL=
MEANLABEL=
NOFRAME
SUMVAR=
TYPE=
Other features:
AXIS statement
PATTERN statement
Data set: FITNESS
Sample library member: GR13N06

[IMAGE]

This example uses the FITNESS data set to chart the mean heart rate for each age group with error bars showing the confidence limits for the average. The response axis label describes the confidence limit for the error bars. To make the error bars easier to read, the program suppresses the frame that the procedure draws around the axis area. Descriptive column head labels in the table of statistics replace the statistic names that appear by default.
