Sample 25596: Fill the area between plot lines using a SYMBOL statement with PROC GPLOT
 |  |  |  |  |  |
The sample code on the Full Code tab shows how to fill the area between two plot lines by concatenating two data sets into one to form a polygon with the data points. It uses a SYMBOL statement to specify a pattern to fill the polygon and to determine the color of the area fill and the outline around the area.
