Hi Xi,<br class="">
<br class="">
have you taken a look at the first example of the vector examples
page<br class="">
<a href="http://ncl.ucar.edu/Applications/Scripts/vector_1.ncl" target="_blank" class="">http://ncl.ucar.edu/Applications/Scripts/vector_1.ncl</a><br class="">
<br class="">
When you want to control the minimum/maximum and interval of the
contour lines use<br class="">
<pre class=""> res@cnLevelSelectionMode = "ManualLevels" ; set manual contour levels
res@cnMinLevelValF = 24.0 ; set min contour level
res@cnMaxLevelValF = 29 ; set max contour level
res@cnLevelSpacingF = 0.10 ; set contour spacing
</pre>
Bye,<br class="">
Karin<br class="">
