RE: [ncl-talk] add plots in ncl

Dear Lin,

You can declare

data=new((/3,4/),float) ; dimension= column, time
 
data(0,:)= column2(:)
data(1,:)= column3(:)
data(2,:)= column4(:)

Then in plotting statement:

plot= gsn_csm_xy (wks,day,data(:,:),res) ; create plot

check the example2 in

http://www.ncl.ucar.edu/Applications/xy.shtml

Good luck

Debasish

Hello, Debasish,

I appreciate your kindly reply:)
My case is as follows, and sorry that I didn't give more clearly expressions
in my last email:

Now I have 4 columns data which looks like this:
----------------------------
1 0.1 0.2 0.1
2 0.2
3 0.2
4 0.4 0.3 0.5
---------------------------
The first column is the time (day), the second column is the data with the
whole column. However, the other two columns with only half data of column
2. How can I plot these 3 lines of time series in one plot? I tried to
seperate these data into 3 files and used gsn_csm_xy3 to plot it. However, I
got 3 y axes which I didn't expect.

Thanks again,
-Lin
