The programs in this
documentation often provide all of the code that you need to generate
the graphs that are shown in the figures. We encourage you to copy
and paste the code into your SAS session and generate the graphs for
yourself. The graphs that you generate in the LISTING destination
will be rendered in their default 640 pixel by 480 pixel size (except
for those examples that show you how to change the graph size).
The graphical output
in this documentation does not show graphs in their default size because
of the limitations of the production system used. The maximum graph
width that can be included in this document is 495 pixels. Hence,
all graphs are scaled down to fit.
When graphs that are
produced with ODS graphics are reduced in size, several automatic
processes take place to optimize the appearance of the output. Among
the differences between default size graphs and smaller graphs are
that the smaller graphs have scaled down font sizes and their numeric
axes might display a reduced number of ticks and tick values. Thus,
the graphs that you generate from the example programs will not always
look identical to the graphs that are shown in the figures, although
both graphs will accurately represent the data.
In addition, a custom
style was created to further enhance the readability of the smaller
graphs. The custom style modifies the supplied LISTING style by further
reducing font sizes so that more space is available to the graphical
elements in the output, and by making some labeling text bold to
enhance the contrast in the graph.
You can use the same
techniques when producing your graphical output. The “Managing
Your Graphics” and " Controlling Graph Appearance with Modified
Styles" chapters explain how to set fonts, DPI, anti-aliasing, and
other features that contribute to producing professional-looking
graphics of any size in any output format.
