The sample code on the Full Code tab illustrates how to create a subgrouped vertical bar chart with the GCHART procedure in which the subgroups for each midpoint total 100%.

To accomplish this, the GROUP= option is specified with the chart variable. The G100 option is used to calculate the percentage statistics separately for each group (midpoint). The options on the AXIS1 statement suppress the label and values for the group axis.
