Sample 25525: Label contour lines in contour plots using PROC GCONTOUR
 |  |  |  |  |  |
This example demonstrates labeling contour levels with the AUTOLABEL option. It also uses AXIS statements to limit the plot to one of the contour areas, and a LEGEND statement to move the legend so the procedure has more space in which to display the Y axis.
