Custom Legend Proc Template

bc — Tue, 11 Oct 2011 15:09:57 GMT

I am using proc template with layout lattice to create 2 side by side ROC figures, each figure having several overlayed lines. The problem I am having is that the same legend is placed under each figure - which is ok for identifying the different groups, except that the legend text also includes the AUC value, which of course will be different depending on the figure. In short, can someone refer me to a reference on how to create a custom legend? I'm using 9.2.
Thanks.

Hi,

Custom legend support is available in SAS 9.3 via the LEGENDITEM statement in the Graph Template Language.

Can you point to an example output and/or template code to see if we can suggest a solution for SAS 9.2 ?

With Regards,

-Prashant.

Template code looks like this:

;

The problem is that both of your plots have the same name ("Step"). Change their names to be unique (e.g. "Step1" and "Step2"), and change the corresponding names in the DISCRETELEGEND statements. That should give you your unique legends.

Hope this helps!
