Manual page for proc_legendentry(PL)
DESCRIPTION
Defines one legend entry.
This entry will be rendered the next time that
proc legend is executed.
Usually, legends are built by successive plotting procs
having a legendlabel attribute. However, if additional
flexibility is needed to make custom legend entries, this
proc may be used, one or more times.
For example, if a scatterplot is being created with various sized
points, there is no automatic way to get a legend of the various
point sizes, so proc legendentry could be executed (probably several
times) to define legend information, then proc legend could be
executed to render it.
