As a "best practice", I would recommend using a data-driven solution, rather than hard-coding the text.  If you hard-code text in the legend, then one day if/when the data changes, then the hard-coded legend will be wrong (which could go un-noticed and compromise the data-integrity of the graph). You don't mention which proc you're using, so here's an example using traditional gplot... Here's a plot with 'M' and 'F' in the legend: legend1 label=none position=(bottom center); proc gplot data=sashelp.class; plot height*weight=sex / legend=legend1; run; Now, instead of 'M' and 'F', let's say we want 'Male' and 'Female' to show up in the legend.  You could either create a user-defined format that makes 'M' and 'F' show up as 'Male' and 'Female' ... or you could add an extra variable to the data, like so ... data mod_class; set sashelp.class; length mod_sex $10; if sex='M' then mod_sex='Male'; else if sex='F' then mod_sex='Female'; else mod_sex=sex; run; legend1 label=none position=(bottom center); proc gplot data=mod_class; plot height*weight=mod_sex / legend=legend1; run; ...
