Ferret users and developers,
I find the "LEVELS=x.xD" qualifier handy, but I thought
it would be even nicer if we had some of the additional
capabilities of the "LEVELS=(lo,hi,delta,ndigits)"
qualifier. For example, I sometimes want to use "LEVELS=x.xD"
but don't want contour labels.
So, I thought it might be useful to extend
the "LEVELS=(lo,hi,delta,ndigits)" qualifier to allow
things like
LEVELS=( , , 0.1, -3)
which is supposed to be equivalent to "LEVELS=0.1D" but
with contour labels omitted. Would this be feasible as
an extension?
(As an aside, it doesn't trigger error in the current Ferret
implementation, but it doesn't have an anticipated result.)
I also think something like
LEVELS=( , , 0.1C)
LEVELS=(-3.3, 4, 0.5C)
would be handy to ensure zero contours are included.
(You might want to use the latter in a script where
the lo and hi of the contour levels are supplied
as arguments.)
Cheers,
Ryo
