25595 - Creating and modifying box plots using the SYMBOL statement with PROC GPLOT

Sample 25595: Creating and modifying box plots using the SYMBOL statement with PROC GPLOT

This sample code shows how to create box plots and how to specify SYMBOL definitions so data outside the box plot range can be represented with data points. It also shows how to change a box plot's percentile range to see if the new range encompasses the data.

The graphics output in the Results tab was produced using SAS® 9.2. Submitting the sample code with releases of SAS prior to SAS 9.2 might produce different results.
