Dear Johny,

from your description I asume that your program creates some file which you 
want to read in octave to plot it (is that correct).
Can you provide a simple example of such file to see the format of the numbers 
how they are delimited and if the file contains some header?
Then I can give you a hint how to read and display it.

In general you can for example look at csvread and similar functions 

help csvread
`csvread' is a function from the file /usr/share/octave/3.2.0/m/io/csvread.m

 -- Function File: X = csvread (FILENAME)
     Read the matrix X from a file.

     This function is equivalent to
          dlmread (FILENAME, "," , ...)

     See also: dlmread, dlmwrite, csvwrite
