I have a curious problem. I am trying to use gdplot2 to contour lines of MSLP.
I want the 1012 line to have a width of 8 instead of 4 (in a PSC device).
My original coding was to make two contours, like this:
CINT = 4 ! 4/1012/1012
TYPE = 1/1/4 ! 1/1/8
The problem is that the two resulting 1012 lines are not exactly the same.
Furthermore, the placement of the label 1012 is not exactly at the
same place neither...
Is there a way to do this in a better way?
