Assigning Descriptive Labels
You can use the LABEL statement to assign more descriptive text to the variables in your SAS/GRAPH output.

Formatting Data Values
You can control how values are displayed by using a FORMAT statement.

Specifying Titles and Footnotes
To specify titles and footnotes for your SAS/GRAPH output, you can use TITLE and FOOTNOTE statements. You can control the appearance of titles and footnotes by specifying the color, height, and font used in the text with the COLOR=, FONT=, and HEIGHT= options. Titles and footnotes have the default values shown for the COLOR=, FONT=, and HEIGHT= options.

Controlling HBAR Statistics
You can control which statistics are displayed to the right of the bars on a horizontal bar chart. You can also use the FREQLABEL=, CFREQLABEL=, PERCENTLABEL=, CPERCENTLABEL=, SUMLABEL=, and MEANLABEL= statements to assign descriptive labels to the statistics.

Controlling VBAR Statistics
By default, only one statistic is displayed for VBAR charts. The OUTSIDE= option allows you to display a statistic above the bars in a vertical bar chart. The INSIDE= option allows you to display a statistic within the bars.

Exporting Graphs
You can export graphs that you have created in SAS to a wide variety of graphics formats, either interactively or by using program statements.

Sizing Graphs
You can size graphs using either the HSIZE= and VSIZE= options or the XPIXELS= and YPIXELS= options, depending on whether you create your graph in the GRAPH window or export your graphs directly to external files using program statements.

Additional Features
You can use a number of options within the GCHART and GPLOT procedures to further enhance your graphs. In addition to the capabilities of the GCHART and GPLOT procedures, SAS/GRAPH software enables you to

specify a number of graphics options
create custom device drivers that contain all the commands for producing a graphics stream file
save multiple graphs at a time
create HTML output using ODS
create custom fonts and custom legends
display data or geographic maps using GMAP
manage catalogs of graphics output using PROC GREPLAY
use PROC GREPLAY to display two or more graphs in one output file
customize graphics output using the ANNOTATE facility
create three-dimensional response surface images using PROC G3D

and much more.

FILENAME fileref 'filename';

GOPTIONS <GSFNAME=fileref> <DEVICE=device-driver>
<HSIZE=horizontal-size <IN | CM | PT>
     VSIZE=vertical-size <IN | CM | PT>>

      YPIXELS=height-in-pixels>;

   <HEIGHT=height-value <units>>

RUN;

III. Sample Program

     filename bargif1 'g:\images\barchart1.gif';
     goptions gsfname=bargif1 device=gif
              xpixels=500 ypixels=400;
     title1 color=red height=0.5 cm
            'Total Fees by Activity Level, Males';
     footnote1 height=0.5 cm color=blue
               font=centx 'Current Month';
     proc gchart data=clinic.admit;
        hbar actlevel / sumvar=fee patternid=midpoint
             sum sumlabel='Fees by Level';
        where sex='M';
        label actlevel='Activity Level';
        format fee dollar5.;
     run;
     goptions hsize=4in vsize=4in;
     title1 color=red height=0.5 cm
            'No. of Clients by Activity Level';
     footnote1 height=0.5 cm color=blue font=centx 
               'YTD FY1998';
     proc gchart data=clinic.admit;
        vbar sex / group=actlevel patternid=midpoint
             outside=cfreq inside=freq;
     run;

IV. Points to Remember

FILENAME, GOPTIONS, TITLE, and FOOTNOTE statements are global and remain in effect until you cancel them, modify them, or end your SAS session.
Be sure to match quotes enclosing text in TITLE, FOOTNOTE, LABEL, and FORMAT statements.
If statistics displayed for VBAR charts are wider than the bars, the statistics may not display properly.
To end a RUN-group procedure, you must submit another PROC step, a DATA step, or a QUIT statement.
