<div dir="ltr"><div><div>Hi Cathy,<br></div>That is strange. I would think the res@mpFillDrawOrder = "Draw" and pres@tfPolyDrawOrder = "PostDraw" combination would definitely work. I just tried running things here, and I was able to plot the polylines over the map fill by swapping gsn_polyline for gsn_add_polyline. <br>
<br></div>I'm not sure why one would have to do that; perhaps a developer can chime in here.<br><div>Adam<br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Mon, Aug 4, 2014 at 3:13 PM, Cathy Smith - NOAA Affiliate <span dir="ltr"><<a href="mailto:cathy.smith@noaa.gov" target="_blank">cathy.smith@noaa.gov</a>></span> wrote:<br>

<div dir="ltr">I tried res@mpFillDrawOrder (which I think is what you were referring to; the other doesn't exist)<br>
<br>
I set to PreDraw, Draw and Post Draw and got the same behavior. I did see some doc here<br>

<br>
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>
<br>
Thanks for the suggestion.<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>
