Christian,
The problem with the 16 degree contour overlaying the other "every 4
degrees contour" is your CINT setting:
CINT = 16;999
Since you only want to draw a single contour that matches your 4 degree
contours
but with the thicker line width, you can use:
CINT = 4/16/16
(the min and max of the same value above will limit to a single contour,
instead of
your above, which is actually 2 contour values).
Note that you can do all three of your plots simultaneously in GDPLOT2
which might
save you some time if you have a number of grids or times to read, eg:
CTYPE = f ! c ! c
LINE = ! 1/2/4 ! 1/2/8
CINT = ! 4 ! 4/16/16

Hello all,
I am trying to generate some plots with contour colored fills.
However, I need also to have some specific contours with a different
thickness of the contour line. FINT and FLINE doesn't allow the line
width to be specified for specific contours.
The solution I found was to superimpose contours using a different line width
using CINT and LINE for the same field.
However, the contours don't match exactly...
Here are the relevant options given to gdcntr (where colors have been
redefined with gpcolors) :
SCALE = 0
HILO
HLSYM
LATLON = 0
CONTUR = 3/1
CTYPE = F
FLINE = 4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19;20;21;22;23;24;25/1
FINT = -32;-28;-24;-20;-16;-12;-8;-4;0;4;8;12;16;20;24;28;32;36;40;44
CLRBAR = 1//CL/.005;.5/.75;.01|1/2/111/221/l/hw
run
CINT = 4
LINE = 1 / 2 / 4
run
CINT = 16;999
LINE = 1 / 2 / 8
run
exit
I thus get an image like this one:
http://meteocentre.com/analyse/local/eur_850_tpw.gif
where we can see that the lines don't match exactly, due to some
smoothing which is not the same.
Using CONTUR = 0 did not solve the problem either, and the plots
looked uglier...
Any solution?
