Merriam-Webster defines a legend as “an explanatory list of the symbols on a map or chart.” We’re used to seeing just that – a table of symbols or a series of colored boxes with a word or two explaining what the symbols or colors mean. In almost every case, this is sufficient. However, what if a legend did more than just explain the colors on the map – what if it had some descriptive or analytic of its own?
This paper discusses techniques to build custom legends using the SAS/Graph Annotate facility. Two realworld examples will be presented. One creates a typical legend and then adds quantitative, descriptive information to it. The other creates a graphic that not only defines the colors on the map, but also stands alone as an analytic display.
