Re: y-axis manipulation for histograms

Hi Neil,

Rick is correct, there's no automatic way to do this.

I'm familiar with this code, so I modified it to force the
percentages to be on the left.

Save the attached file, make sure you load it after you load "gsn_code.ncl", and then
call "gsn_histogram_mod" instead of "gsn_histogram".

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "./gsn_histogram_mod.ncl"

...

plot(0) = gsn_histogram_mod(wks,enws,res)
. . .

--Mary
