42864 - Scatter plot of groups with an overall regression line

Sample 42864: Scatter plot of groups with an overall regression line

This sample illustrates how to generate a scatter plot of groups overlaid with an overall regression line using the GPLOT procedure. The PLOT statement generates the scatter plot of groups; the PLOT2 statement generates an overall regression line for all groups.

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.
