O.3.2 Fixed number of labels</A>

<P>
We now exercise the option for specifying exactly how many labels each contour line
should have:

By selecting only one label per contour and requiring that labels only be placed on
contour lines whose length exceed 1 inch, we achieve the effect shown in Figure&nbsp;<A HREF="#fig:GMT_App_O_2">O.2</A>.
