Re: combine four views into one plot

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Gao Rongzhen,
                 Your dataset contains data on two different time axis.
The seasonal data has 224 points (a1& a2) but the monthly data has 564 
points (b1,b2,c1,c2,d1&d3). I think in Ferret it is really difficult to 
read these data on to proper grid because whatever may be the grid/method 
you are using the data on 3rd column after the line 224 will be assigned 
between 1st column and the 3rd column itself !!! (does anybody have any
solution ??) For example : let this be the data in test.dat

        10  100
        20  200
        30  300
            400
            500
            600
            700

 now read this data in Ferret

          yes? define axis/x=1:7:1 xax
          yes? define grid/x=xax   gf
          yes? file/grid=gf/var="a1,a2" test.dat
          yes? list a1
                        ........................
            1   / 1:   10.0
            2   / 2:   20.0
            3   / 3:   30.0
            4   / 4:  400.0
            5   / 5:  600.0
          yes? list a2
                        ........................
            1   / 1:  100.0
            2   / 2:  200.0
            3   / 3:  300.0
            4   / 4:  500.0
            5   / 5:  700.0

 So my suggestion is to save the seasonal data to a new file (use vim,
you can do "column" operations easily) and monthly data to another file.
Then open these two datasets in Ferret, read on to proper time grid.
Since the start and end points of seasonal and monthly time axes are
different please make sure that you are creating the plots over exactly
same range of time axis.

   And.....the answer to your question...that kind of a plot you can
make using proper combination of 4 viewports. Plese see the attachment
for an example (using the same data you send earlier).

Hope This Helps

With Regards

Jaison
