The CBACK= option is
valid on all devices but can be ignored by some (for example, plotters).
Specify the default in the
Gcolors window
of the device entry.
Note: This option overrides the
Background and Foreground style attributes in the graph styles. For
more information about graph styles, refer to the TEMPLATE procedure
documentation in
SAS Output Delivery System: User's Guide.
If you explicitly specify
a background color with the CBACK= option, the background color that
you select should contrast with the foreground colors.
If the IBACK= option
is in effect, an image will appear in the background in place of the
color specified with the CBACK= option.
