 |  |  |  |  |  |
The sample code on the Full Code tab uses PROC GPLOT together with the Annotate facility to label data points in a two-dimensional plot.

The sample code below uses PROC GPLOT together with the Annotate facility to label data points in a two-dimensional plot.
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.
