Re: time series in unix time

[Roelof Burger <roelof@xxxxxxxxxxxxxxxxx>]

Dear ferreters,
i'm still a struggling new user:

i tried the following:
defining a coordinate variable - 


        int time(time) ;
                time:long_name = "Seconds since base_time" ;
                time:point_spacing = "even" ;
                time:time_origin = "28-JAN-1999:14:02:40" ;
                time:units = "sec" ;



Now i only have to say: 'PLOT variable' to come up with the correct axis.

i also had to change the variable that it count from 1 and not zero.
