All graphical display (images, contour plots, X/Y graphs) may contain
additional annotation labels. These text labels may be arbitrarily
placed and may include arrows to point to areas of the graphics. The
annotation labels and arrows may be defined in either page coordinates
or data coordinates (See Section 21,
Page ). By using data coordinates the relative
position of the label or arrows will not change if different regions of
the data are displayed.
Many different annotation labels may be added and their style may be
controlled individually using SET ANNOTATION STYLE (See
Section 15.91, Page )
and SET ARROW STYLE (See
Section 15.92, Page
).
