Hi Xiaoming,<br>
<br>
you should set <br>
<pre> res@gsnDraw = False
res@gsnFrame = False
</pre>
if not set to False, the streamline plot will overwrite the contour
map.<br>
<br>
Bye,<br>

<span></span>Hello<br>
I would like to overlay streamline on terrain height using
gsn_csm_streamline_contour_map.<br>
But I only get streamline, but no terrain height. See the
following figure. <br>
Anybody knows what is happening? I attached my ncl script. <br>
