Controlling Graph Resolution with The SVG Devices

The default resolution for the SVG devices is 96 dpi. Because the SVG devices are Universal Printer shortcut devices, you cannot change the resolution using options in the GOPTIONS statement.
If you are sending output to the HTML or LISTING destinations, you can control the resolution with the IMAGE_DPI= option on the ODS destination statement. For example:
ods listing image_dpi=600;
