Annotating box plots

ketch — Fri, 18 Mar 2011 17:48:17 GMT

Hello.
I am using Proc Boxplot to make a grouped box and whisker plot. I am using annotate to draw brackets between boxes indicating statistically significant pair-wise differences.

How do I get three different color fills inside each of the three locations (Neck, Chest, Groin) and how do I then create a legend outside of the plot area that will include the color definition as well as the p-value labels that I currently have showing inside the plot area?

By the way, I would love to do this using Proc SGPanel. Does anyone know if SGPanel can be "tricked" into somehow adding brackets to a grouped boxplot?

Thanks,
Norma Ketchum

If you can't find another way, perhaps this example will be a good starting-place for creating a totally custom boxplot, using annotate to draw it ...
