[ferret_users] Including contour lines in the shaded plot

[Sudev Das M P <devdas.pnr@xxxxxxxxx>]

Hi,

I like to include contour lines in the shaded plot. I tried doing this
but then the color bar

disappeared from the plot. The script I am using is given below.
Please give me your

advise to solve this problem.

Thanks,
Sudev
