Thx Rick for your quick response.<br>
<br>
Playing a little bit with the smooth-Parameter of the cn-resources
yields the plot attached.<br>
<font face="Courier New"><br>
<b>res@cnSmoothingOn = True</b><b><br>
</b><b>res@cnSmoothingDistanceF = 0.005 ;(usw 0.005 ... 0.03)</b></font><br>
<br>
An area left is getting colored. (there is no station!)<br>
This is risky i think, if I set the parameter (hardcoded). I never
know what the graphics will look like.<br>
<br>
Do you think i should try interpolate the station data from my
unstructured grid to a rectilinear grid using <b>natgrid</b>? <br>

<div bgcolor="#FFFFFF"> Hello,<br>
<br>
I tried to plot station data of surface temperature on a map
as a contour plot. I'm not satisfied with the result (see
attached picture AreaFill.png).<br>
It all seems so angular. My grid is not regular because of
the station data. <br>
<br>
Switching from AreaFill to RasterFill results in a litte
better plot (smooth contours) as you can see in the picture
attached (RasterFill.png).<br>
<b><font face="Courier New">res@cnFillMode = "AreaFill"<br>
res@cnFillMode = "RasterFill"</font></b><br>
<br>
I tried to regrid the triangular mesh (unstructured) station
data to a structured grid using <b>natgrid</b>?<br>
But it fails ...<br>
<br>
Do you have any ideas for a better plot? Or what is the
correct way to plot such station data as contour?<br>
<br>
Regards<br>
