[ncl-talk] gsnContourPlot without a border

[Mary Haley]

Hi Michael,

I think the key, which may seem somewhat counterintuitive, is to not set
res at gsnMaximize = True. The reason for this is that gsnMaximize is actually
trying to resize things so they'll fit in a unit square, and apparently
it's adding a little of a margin (feature or bug, I'm not sure).

To force no border, I suggest not setting gsnMaximize, and you may also
want to set vpXF=0, vpYF=1, vpWidthF=1, and vpHeightF=1.

I've created an example script, attached.

--Mary
