If you <code>display</code> when one dimension varies, you get a 1-D line graph (by default). If you <code>display</code> when two dimensions are varying, you get a 2-D contour plot (by default). <p> GrADS will automatically overlay the output from each successive display command.<br> To clear the display, enter: <p> <dd> <code>clear</code> (or just <code>c</code>) </dd> <p> <H3>Examples</H3><P> The simplest example of an expression to display would be a variable named by the default data file.<br> </body> </html>
