A c_linestyle of 1 which I need for my contours to cooperate with continental
boundaries draws pieces of some contours as solid (instead of the intended
dotted) lines. Anybody have a solution?
The IDL Ref. Guide acknowledges that the LINESTYLE keyword in CONTOUR doesn't
work very well, saying
"The cell drawing contouring algorithm draws all the contours in each cell,
rather than following contours. Since an entire contour is not drawn as a
single operation, the appearance of the more complicated linestyles will
suffer. Use of the contour following method (selected with the FOLLOW
keyword) will give better looking results in such cases."
However, under the discussion of FOLLOW they say it is not necessary any more,
and FOLLOW does no good at all. My call to CONTOUR looks like this:
CONTOUR,DATA,XB,YB,POS=POS,/DEV,$
/NOER,XST=STY,YST=STY,C_COL=COL,C_THI=C_THI,C_CHARSIZ=C_CHAR , $
LEV=LEV,/FOLLOW,C_LI=C_LI, MAX=maxzz, C_LAB=C_LAB, $
SUBTITLE=SUBT, TICKLEN=TICL, CHARS=CHS, XMI=XMI, YMI=YMI, $
XTICKS=XTI, YTICKS=YTI, XTICKN=XTN, YTICKN=YTN, XTICKV=XTV, $
YTICKV=YTV, FONT=FONT, TITLE=TITLE, XTITLE=XTITLE, $
YTITLE=YTITLE, XRA=XX, YRA=YY
Thanks.
