Example Using the Contour Platform

To create a contour plot, you need two variables for the x- and y-axes and at least one more variable for contours. You can also use several y-variables. This example uses the Little sample data table. X and Y are coordinates of a pond. Z is the depth.

1. Select Help > Sample Data Library and open Little

2. Select Graph > Contour Plot.

3. Select the X and Y coordinates and click X.

4. Select the depth, Z, and click Y.

Note: In a contour plot, the X1 and X2 roles are used for the X and Y axes.

5. Click OK.

Figure 10.2 Example of a Contour Plot with LegendĀ 

The x- and y-axes are coordinates and the contour lines are defined by the depth variable. This contour plot is essentially a map of a pond showing depth. To see the contours more clearly, click the red triangle next to Contour Plot for Z and select Fill Areas.
