<br>
<br>
Attached, you find a screenshot of a plot produced by ncl 6.3.0 (Ubuntu 16.04.01) .<br>
<br>
There are hundreds of very fine, rectangularly-spaced, vertical and horizontal white lines, likely exactly marking the boundaries of each grid cell of my input field (a netcdf file).<br>
<br>
How can I disable these fine white lines?<br>
<br>
They appear when I use "CellFill".<br>
<br>
Currently, I create "PDF" output with NCL. I also tried "PS", same problem here.<br>
<br>
Here is an extraction of the ressources I use in my ncl plot script:<br>
<br>
varR@cnFillOn = T ;<br>
varR@cnFillOpacityF=1<br>
varR@cnFillMode="CellFill"<br>
varR@cnCellFillEdgeColor=-1<br>
varR@cnCellFillMissingValEdgeC<wbr>olor=-1<br>
<br>
By the way, I figured out that, if I set the @cnCellFillEdgeColor= to a value of 0 or 1, all these lines become really thick and eg. of bold white or black color. This is not what I want but maybe these ressources are somehow linked to my problem/solution?<br>
<br>
I like to let all cell-edge-lines disappear in my plot, so if I set this option to @cnCellFillEdgeColor=-1<br>
but the lines are still there (attached), they do not disappear.<br>
<br>
Any idea/help on that?<br>
