Re: [ferret_users] plotting decadal timeseries

[Karl Smith - NOAA Affiliate <karl.smith@xxxxxxxx>]

Hi Marco,

Use "year" as the unit and set the step size to 10.

So:

DEFINE AXIS /T="1-JUL-1001":"1-JUL-2000":10/UNIT=year/T0="1-JAN-1000" tdecadal

Of course this mean the T values are 1, 11, 21, ... for this example, but presumably you are interested in the dates and not the T values.

Hi Ferretters—

I have decadal output stored in netCDF files that don't have a correct
time axis defined.  How could I plot a time series?

I have tried this, having 100 decadal averages (k=1:100):

    yes? define axis/t="1-jul-1001":"1-jul-2000":1/units="10 years" tdecadal
    yes? define grid/t=tdecadal gdecadal

I have these, possibly related, issues:

- The units "10 years" and "decades" are not recognised as standard units.
- The data is plotted over the first 100 years, instead of being spread
  out over the whole 1000 years range.

Either making Ferret understand decadal average timesteps, or making
the 100 timesteps spread out over the 1000 years would help me out!
