Hi,
The problem similar to this one is written in manual, about 
reading ascii file, and also in demo program file_reading_example.jnl

Let your data file is data.dat which consists of two columns of values.
First col are x's and second one are y's
using ferret

? file data.dat
? file/file=x,y/col=2 data.dat

Now your ferret understand what x and y are

Second step you must put your data into a definite grid by using 
one of the GO tool (objective.jnl) . Further, see objective_analysis.jnl
Please let me know if you need more explanation
