Creating Bar and Pie Charts

Additional Features

You can specify a number of other statements and options to enhance your charts. For example, you can use the GROUP= option to categorize data.

        proc gchart data=clinic.admit;
           hbar sex / sumvar=weight type=mean
                group=actlevel patternid=group;
        run;

Example of GROUP= option.

You can use the SUBGROUP= option to subdivide bars by category. You can also control how colors and patterns are assigned using the PATTERNID=SUBGROUP option and multiple PATTERN statements. In the PATTERN statements below, the value lib specifies the color light blue and the value lig specifies the color light green.

        pattern1 color=lib;
        pattern2 color=lig;
        proc gchart data=clinic.admit;
           hbar age / sumvar=weight type=mean
                subgroup=sex patternid=subgroup mean;
        run;

Example of SUBGROUP= option.

For horizontal bar charts, you can control which statistics are displayed to the right of the chart. The first chart below shows the default statistics for a horizontal bar chart. The second chart shows a GCHART statement which requests only the statistic FREQ.

        proc gchart data=clinic.admit;
           hbar sex / group=actlevel
                patternid=group;
        run;

Default statistics for HBAR charts.

        proc gchart data=clinic.admit;
           hbar sex / group=actlevel
                patternid=group freq;
        run;

Example of specifying a statistic for an HBAR chart.
