Re: trouble in plotting Pacific region

Hi Bo,
Assuming that your data's longitudes run from 0->360 (you can check that
by doing a printVarSummary(data)), you should specify lonL = 120 and
lonR = 320.. For example:

lonL = 120.
lonR = 320.
printVarSummary(data)
data_subset = data(:,:,{lonL:lonR}) ; data = time x lat x lon
printVarSummary(data_subset)

If your data's longitudes run from -180:180 and you wish to select
40:320, use the lonFlip function prior to subsetting..
