Re: [ferret_users] vectors thicker?

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Jimmy,
           If the NaN (rather missing) value information is correct, then
you should get anything over those grid points with Nan values, not even 
dots (irrespective of the thickness). You have to do one more step, after
setting NaN values to 1e-34

    set var/bad=1e-34 variable_name

With this step, Ferret will not attempt to put either dots or asteriks 
any more. Please note that the default missing value assigned by Ferret
is -1E+34, and there is a difference in behaviour between variables 
defined in a Ferret Session and that readed in from input NetCDF files.

 Please note that, the "return" command can be used to know the missing
value of a variable as :

    say `variable_name, return=bad`

Hope this informations will help you to resolve your problem. Please 
let me know, if you have any questions.

With Regards,

Jaison
