Re: How to avoid being truncated and the position of legend?

Another thing you can try, if you are using a gsn_xxx type of routine
and using "pmLegendDisplayMode" to turn on the legend, and that is to
set res_at_gsnMaximize = True. This resource will internally cause NCL to
take a look at your plot, and resize it to fit whatever output device
(X11 window, PS file, etc) you are using. If the plot is too big for
the output device, NCL will then make the plot smaller so that it will
fit.

However, if you are drawing the legend yourself, or adding other
things to the plot later (like text strings), then Adam's suggestion
is the one to use.
