GCONTOUR Procedure

Overview: GCONTOUR Procedure

The GCONTOUR procedure enables you to generate two-dimensional plots representing three-dimensional relationships. For example, the following Simple Contour Plot displays various depths of a lake. The dimensions of the lake are plotted on the x and y axes. The z variable is plotted as the third dimension, and is displayed as uniquely colored contour lines.

With PROC GCONTOUR, you can do the following actions:
  • use AXIS statements to customize the axes
  • use line styles and patterns to emphasize the contour levels
  • use reference lines to see how (x,y) combinations align to z values
  • use SYMBOL statements to customize labels or highlight data trends
