Re: Fill Value color transparent

Hi Jonthan,

Without seeing your script, I'm not sure how you are doing the various overlays. By "NCL5" and "NCL6", I assume you mean NCL V5.1.2 and NCLV 6.1.2?

You can certainly make the fill value areas transparent, but you have to be using a cnFillMode of "AreaFill" (the default) or "CellFill", b/c in V6.1.2 and earlier, "RasterFill" doesn't support transparency.

See example 10 at:

http://www.ncl.ucar.edu/Applications/mask.shtml#ex10

In the next release of NCL, transparency will be supported with RasterFill.

If you want me to look into the issue between NCL 5.x and 6.x, then a script and data would help.

The goal is to overlay images close to each other for a presentation, however the white background in the NCL6 plots causes the data to be obscured. Is there a way to turn off the fillvalue/white background?
