The GCONTOUR Procedure

Example 2: Labeling Contour Lines, Modifying the Horizontal Axis, Modifying the Legend

Procedure features:	AUTOLABEL, HAXIS, LEGEND
Data Set	SASHELP.LAKE
Sample library member:	GCTLABEL

[untitled graphic]

This example modifies Simple Contour to label contour levels with the AUTOLABEL option. The SYMBOL statement used with the AUTOLABEL option enables you to customize the attributes of the contour lines and labels.

In this example, SYMBOL1 and SYMBOL7 assign text labels, text fonts, text height, and text and line color for the first and seventh contour level lines. SYMBOL2-SYMBOL6 define the text height, and the text and line color for contour level lines 2-6.

Additionally, the LEGEND statement attributes are modified to reposition the legend closer to the data.
