[ncl-talk] problem with ShadeGeLeContour

[debasish mazumder]

Hi Mary,

The problem related error is solved with updated version but Script is 
not working properly.
opt at gsnShadeMid = 17
plot2   = gsn_csm_contour(wks,gsn_add_cyclic_point(cv), res2)
plot2   = gsn_contour_shade(plot2,-0.1,0.1 , opt)

istead of sheading the values between -0.1 and 0.1, It only shaded 
negative values.
Any help will be appreciated.

with regards
-Deb
