<p>Hi, Thanks for responding :) I was wondering if the contours
might not line up if I did that (unless I did raster fill maybe)?</p>
<p>But, I think I will do that so I can get something. <br>
</p>
<p>The easiest NCL solution is that the transparency value would
become an array. An ability to have no colors drawn at all (even
background) for contouring outside of a specified range would also
work.</p>

Hi Cathy,
<div><br>
</div>
<div>I had a similar problem before. It might work to duplicate
the variable and replace the categories you want to be
transparent with missing values. That way they won’t be
colored. </div>

<span>I am hoping I missed this in the doc. I'd like create
a map that is colorfilled (either contour or raster). I
would like the lowest 3 contour ranges to be transparent
and the rest not. I can't figure out how to do this. I
tried overlay and I wasn't able to not color part of a map
so the overlay worked. Also, I don't see you can set an
array of transparency for each color.</span><br>
<span></span><br>
<span>Any suggestions would be appreciated.</span><br>
