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