2D shaded time series plot

[Steve Knox <stevek@xxxxxxxxxxxxxxxxxx>]

  I have a netcdf file with 1 variable, tmp  for latitudes -90 to 90 (by 1/2 deg) and longitudes -180 to 180 (by 1/2 degree)
The time unit is "months since 1900-01-15 00:00:00". There are 1200 months (100 years).
I would like to plot year along the x-axis and month (1-12) on the y-axis for a paricular spatial aggregation.
The "value" plotted should be a shaded area, representing the value at each month. I want to look for monthly
or seasonal variations over time.

12  B     A


 
 
 
 
 
 ...
 3   A
 2   B    A
 1   B    B      
      
    1901     1902    ... 
                                         
Where the letters" images would actually be shaded areas.

Is this possible with Ferret?

yes? use tmp
yes? show data
     currently SET data sets:
    1> ./tmp.cdf  (default)
 name     title                             I         J         K        
L
 TMP      Surface air temperature          1:720     1:360     ...      
1:1200
