24935 - Create a shadow behind a needle plot with PROC GPLOT

Sample 24935: Create a shadow behind a needle plot with PROC GPLOT

This sample uses a dummy Y variable to draw a thick plot line with PROC GPLOT that appears to be a vertical bar raised off of the background, which creates a shadow effect.

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.
