Exporting SAS/GRAPH Output Using Program Statements

To export SAS/GRAPH output using program statements, you specify

a destination for the output
a device driver that creates the type of graphics output that you want.

Specifying an Output Destination

To specify an output destination, you

use a FILENAME statement to assign a fileref to the external file where you want to send the output

General form, FILENAME statement:

FILENAME fileref 'filename';

where

fileref is a valid SAS name you associate with an external file. The fileref must be 1 to 8 characters in length, begin with a letter (A-Z) or an underscore (_), and continue with any combination of numbers, letters, or underscores. You can also use the dollar sign ($), pound sign (#), and at sign (@) in filerefs.
filename is the fully qualified name or location of the file.

The filename must be the complete physical name of the external file and must include a file extension that indicates what type of graphics file you are creating, such as .GIF for a GIF file.

assign the fileref to the GSFNAME= graphics option in the GOPTIONS statement.

General form, GOPTIONS statement:

GOPTIONS <options-list>;

where options-list can be one or more graphics options.

With the exception of RESET=, graphics options can be listed in any order in a GOPTIONS statement. RESET= should be the first option in the GOPTIONS statement.

For example, the following FILENAME statement assigns the fileref Mygif to the file C:\My SAS Files\Hbar1.gif in the Windows environment. Then the GOPTIONS statement specifies Mygif as the output destination for the SAS/GRAPH procedure that follows.

     filename mygif 'c:\my sas files\hbar1.gif';
     goptions gsfname=mygif;
     SAS/GRAPH statements...
     run;

Specifying a Device Driver

To specify the device driver, you use the DEVICE= graphics option in the GOPTIONS statement.

General form, DEVICE= option:

DEVICE=device-driver

where device-driver is a valid device driver.

For example, to specify your output as a GIF file, you add the following DEVICE= option:

     filename mygif 'c:\my sas files\hbar1.gif';
     goptions gsfname=mygif device=gif;
     SAS/GRAPH statements...
     run;

Example: Exporting Two Charts

The following SAS program creates a bar chart and a pie chart, each stored in a separate GIF file.

     filename bargif 'g:\images\barchart.gif';
     goptions gsfname=bargif device=gif;
     proc gchart data=clinic.admit;
        vbar actlevel / sumvar=fee;
     run;
     filename piegif 'g:\images\piechart.gif';
     goptions gsfname=piegif device=gif;
     proc gchart data=clinic.stresstest;
        pie tolerance;
     run;
     quit;
