Sample 25601: Using shapes in scatter plots with PROC G3D
This program demonstrates how to use shape symbols and color to distinguish information for various iris species. The second plot request suppresses the needles that connect data points to the horizontal plane, and adds reference lines to make it easier to interpret the data values.

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.
