simple plot

[Wendy Wang <wwang@xxxxxxxxxxxxx>]

Hi ferret_users,

I have a dataset like:

 name     title                                  I         J         K 
    L
 S        Salinity                         1:161     1:91      1:21      1:636
 TEMP     Temperature              1:161     1:91      1:21      1:636

I want to make one scatter plot using k=2 data:
X axis is temp, Y axis is S. Then do the linear fit.

Does someone know how? It may be simple,
but I cannot figure it out.

Thanks in advance.
