Hi Izidine,
Do you want to keep the time resolution of the original data, so that
you see all of the variations, but not show those straight the lines
between the end of Feb and the start of Dec? Or do you want to take an
average over each DJF season, and plot a time series where each season
is represented by one point?
To do the first, you could use the command
yes? CANCEL AXIS/CALENDAR `temp,RETURN=taxis`
yes? PLOT temp[...
This would set the T axis so it is no longer a formatted time axis.
Your data will plot as a simple time series, but the labeling of the
axis with months and years will no longer be in place; the horizontal
axis will just be labeled with time coordinates number-of-days-since
the time origin.
To make a time series with a single point for each year, define a
yearly time axis with the time coordinates centered in the middle of
January, and regrid your data to that axis:
yes? DEFINE AXIS/T=16-jan-1981:16-jan-1999:1/units=year
tyear
yes? LET tempyr = temp[gt=tyear@ave]
yes? PLOT temp[d=2,x=30:42@ave,y=-27:-10@ave]
Try some of these things and see

Dear ferret users
I have a daily data set with only one season (DJF) from 1981 to 1999.
1> ./
Tmax.DJF.daily.1981_1999.echama2.nc
name title I J
K L
TEMP TEMPERATURE AT 1.5M 1:127 1:110
1:1 1:1680
I would like to plot a time series of the seasons but I don't know how
to set up
the x-axis.
In attachment is a plot for better understanding of my problem
I use the command:
plot temp[d=2,x=30:42@ave,y=-27:-10@ave,l=1:270]
Thanks in advance
