Re: plotting the image of CALIPSO 532nm attenuated backscatter

Hi Vivian,
Unfortunately, there does not exist a way to automatically alter the
formatting of the label bar labels before the plot is created.
See example #7 here:
http://www.ncl.ucar.edu/Applications/labelbar.shtml#ex7

The most straightforward thing to do is to explicitly set the label bar
labels yourself by using function codes to enable superscripting:
res1@lbLabelStrings = (/"1 x 10~S~-4~N~","2 x 10~S~-4~N~",.....
(Note that I'm assuming you've changed your function code from a : to a
~. If you haven't, and/or you do not have a .hluresfile in your home
directory, see here:
http://www.ncl.ucar.edu/Document/Graphics/hlures.shtml )

I looked into using sprintf to automatically do this for you:
http://www.ncl.ucar.edu/Document/Functions/Built-in/sprintf.shtml

But it seems that it will not print things out exactly as you want them:
"1.0 x 10~S~-4"

Anyway, hope that helps. If not, please respond to ncl-talk..
