Labels can be added to contours one of two ways:

1. The right portion of the Contour Label Options dialog controls the generation of automatically spaced contour labels. The generation of automatic contour labels can be toggled on or off. If the toggle is on, specify which contours should be labeled and the distance along the contour between labels.
2. In some modules, contour or function labels can be added manually to an image by selecting the Contour Labels tool in the Tool Palette and clicking on the mesh or grid where a label is desired. If the Place on contours option in the upper right portion of the Contour Label Options dialog is selected, the label is moved to the closest contour and the contour is labeled there. If the Place under cursor option is selected, the label shows the value of the point at the click location and is placed there. This option is useful to post data set value labels in regions where there are no contours. Contour labels can be deleted by holding down the SHIFT key while clicking on a label.

The bottom portion of the Contour Label Options dialog control how the labels appear. On the left side, enter how many digits of accuracy are desired. The default will match the contour legend. On the right side, select a color and font for the label. For labels on contours, also specify if the contour are to be oriented to lie along the contour.
