which is along the lines of what you suggested but didn't seem to work
for the routines I used. I wonder if there is a way to draw the
polylines last instead of the shaded fill first?<br>

Hi NCLers<br>
I'm having trouble getting a polyline to appear OVER a map with<br>
continents shaded. I have simplified code below which reproduces the<br>
problem. The code draws a basic map (shading is default) and then a box<br>
on the map using gsn_polyline . You can run code and then look at<br>
<a href="http://fluffy.ps" target="_blank">fluffy.ps</a>. The box just shows up where there is no shading. I verified<br>
in testing that the lines show up as long as they aren't located where<br>
the shading is. How can I control the order of shading so it is done<br>
before the polylines?<br>
<br>
NCL version is 6.2.0 on a 64 bit linux server.<br>
<br>
Thanks!<br>
Cathy Smith<br>
