Statistical Graphics Using ODS

Specifying the Size and Resolution of Graphs

Two factors to consider when you are creating graphs for a paper or presentation are the size of the graph and its resolution. You can specify the size of a graph in the ODS GRAPHICS statement. The following examples show typical ways to change the size of your graphs:

ods graphics on / width=6in;
ods graphics on / height=4in;
ods graphics on / width=4.5in height=3.5in;

You can change the resolution with the IMAGE_DPI= option in any ODS destination statement, as in the following example:

ods html image_dpi=300;

The default resolution of graphs created with the HTML and LISTING destinations is 100 DPI (dots per inch), whereas the default with the RTF destination is 200 DPI. An increase in resolution often improves the quality of the graphs, but it also increases the size of the image file. See the section Graph Size and Resolution for more information about graph size and resolution.
