[ncl-talk] problem with gsn_csm_contour in drawing a globe

[Guido Cioni]

Hey Frank,
I’m pretty sure (but not completely) that the first problem will be solved by setting gsnAddCyclic = False. For the second one it seems that you are correctly setting the gsnMaximize resource to True, so I don’t know what you could do… Can’t you just cut the resulting png file? It seems that changing the paper orientation wouldn't affect the plot since it is squared, but you can try to play around with the resources related to the Maximize option (maybe setting  gsnBoxMargin <https://www.ncl.ucar.edu/Document/Graphics/Resources/gsn.shtml#gsnBoxMargin> to 0.0?); see hereinafter. 

gsnMaximize
If set to True, then any plot drawn by a gsn <https://www.ncl.ucar.edu/Document/Graphics/Interfaces/> function will be maximized in the workstation on which it is being drawn. For an X11 window or an NCGM file, this means the plot will be expanded to fill the biggest possible space within a square, with a small margin around all edges. You can get rid of this margin by setting gsnBoxMargin <https://www.ncl.ucar.edu/Document/Graphics/Resources/gsn.shtml#gsnBoxMargin> to 0.0. The aspect ratio will be preserved. For a PostScript or PDF file, the plot will be expanded to fill the biggest possible space on an 8 1/2" x 11" sheet of paper.
For a PS or PDF file, you can change the default paper size, margins, or orientation with the resourcesgsnPaperOrientation <https://www.ncl.ucar.edu/Document/Graphics/Resources/gsn.shtml#gsnPaperOrientation>, gsnPaperMargin <https://www.ncl.ucar.edu/Document/Graphics/Resources/gsn.shtml#gsnPaperMargin>, gsnPaperWidth <https://www.ncl.ucar.edu/Document/Graphics/Resources/gsn.shtml#gsnPaperWidth>, and gsnPaperHeight <https://www.ncl.ucar.edu/Document/Graphics/Resources/gsn.shtml#gsnPaperHeight>
