Re: problem with contour InfoLabel

Hi Brian,

This looks like a bug, and I was able to see the same results from
the script you included (thanks for providing it).

As for a work-around, you might try setting the cnInfoLabelFormat
resource to a string that gets rid of the exponents. The default is
the cryptic string "*+^sg". If you remove the "s" part of this, you
get rid of the exponents:

   res = True
   res_at_cnInfoLabelFormat = "*+^g"

   plot = gsn_csm_contour(wks,u,res)

This casuses the information label to be:

    "CONTOUR FROM -8e10 to 8e10 by 2e10"

Let me know if this is not an acceptable work-around. Meanwhile, I'll
see about a fix.
