Re: Questions on boxplot for Missing Value, Thanks!

Hi Xiaoming,
The boxplot function was not designed to handle missing data in the
input Y-array. I have added that functionality to the code, and have
attached the new function here. load this function after you load
shea_util.ncl:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl"
load "boxplot.v3.ncl"

or, alternatively, go into shea_util and replace that version of the
boxplot code with the attached version.

This new version of the boxplot code will be the default as of NCL 6.0.0.

Let me know if you encounter any problems..
