<p>I've tried flipping the order of those last two, but with no success. It's honestly not a huge issue, but I thought I would pass it along. I could pass along my script if you would like (I would here, but it's *very* long.)</p>

<div>Hi Nick,<br>
<br>
</div>
I unfortunately am not able to duplicate this issue (?) I've used 6.3.0, and I cobbled together a plot that uses, in order<br>
<br>
</div>
gsn_csm_contour_map<br>
</div>
gsn_add_text to the contour<br>
</div>
gsn_csn_vector<br>
...<br>
</div>
overlay(plot, vector)<br>
<br>
</div>
and I've tried to used the same resources everywhere. Are any other opacity resources getting set in the script?<br>
<br>
</div>
I'm not sure what to tell you...<br>

That likely is indeed a bug and I will look into it and let you know.<br>

That's a nice looking animation BTW!<br>

<p>Hi All,<br>
I *think* I may have found a bug. For reference, I'm using NCL 6.3. Long story short, I make a complex plot in real time with lots of overlays of various variables, mostly for aid in severe weather prediction/detection, using NY Mesonet data. I denote strong
wind gusts, and change their opacity to reflect how long ago they occurred. Here is a sample loop from today: <a href="http://www.atmos.albany.edu/facstaff/nbassill/live/NCLexample.gif" class="m_8669426313058719336m_8453489966361494127OWAAutoLink" id="m_8669426313058719336m_8453489966361494127LPlnk485893" target="_blank">http://www.atmos.albany<wbr>.edu/facstaff/nbassill/live/<wbr>NCLexample.gif</a><br>
<br>
You'll notice the winds gusts (properly) change their opacity with time. The weird thing is that the reference vector changes its opacity with time as well, despite the fact I'm not instructing it to. The code is very long, so I'll just send the important parts
of the script, below:</p>
<p><br>
</p>
<p>....</p>
<p>;;;; this part plots the site winds, and determines opacity based on time</p>
<p></p>
<div><br>
</div>
<div>size = dimsizes(sitewindtime)-1</div>
<div>tres = True </div>
<div>tres@tfPolyDrawOrder = "PostDraw"</div>
<div>tres@txFont = "helvetica-bold"</div>
<div>tres@txFontHeightF = 0.013</div>
<div>;tres@txFontThicknessF = 3</div>
<div>do n=0,size(0)-1,1</div>
<div> if sitewinds(n).gt.25</div>
<div> tres@txFontOpacityF = 1-(sitewindtime(n)/35)</div>
<div> stationtext = gsn_add_text(wks,plot,round(si<wbr>tewinds(n),3),sitewindlons(n),<wbr>sitewindlats(n),tres)</div>
