[ncl-talk] CellFill issue: How to disable all fine white lines around each grid cell in the output PDF plot (see attached)

[Erik Jan Schaffernicht]

Attached, you find a screenshot of a plot produced by   ncl 6.3.0  (Ubuntu 16.04.01) .

There are hundreds of very fine, rectangular, vertical and horizontal white lines, likely marking the boundary of each grid cell of my input field (a netcdf file).

How can I disable these fine white lines?

They appear when I use  "CellFill".

Currently I create  "PDF" output.  I also tried "PS", same problem here.

Here is an extract of the ressources I use for during my plot:

   varR at cnFillOn     = T ;
           varR at cnFillOpacityF=1
           varR at cnFillMode="CellFill"
            varR at cnCellFillEdgeColor=-1
            varR at cnCellFillMissingValEdgeColor=-1

If I set the    @cnCellFillEdgeColor=    to a value of 0 or 1 these all lines become really thick and eg. of white or black color.

But if I set this option to  "-1"     the lines are still there and do not disappear.

Any idea/help on that?

Erik
