    OK, and what part is giving you trouble? I see you tagged with gnuplot, so should we assume you want to use that tool? What do you have so far? If you don't share what you've done with us, we'll just waste your time telling you things you've already tried. So please edit your question and explain what you have so far and what you need help with. Commented Nov 27, 2017 at 11:44
  • the data is generated using a tool. It gives output in this format. I tried using the tool 'plot. Says these is an undefined symbol in the file. Commented Nov 27, 2017 at 12:08

    Well, that's precisely the sort of information that should be in the question. Please edit your question and i) tell us what tool you used; ii) show how you imported the data into gnuplot; iii) show us the exact error message you got. We can't help you fix a problem if you don't tell us what the problem is. Could the data be coming from a Windows program? Commented Nov 27, 2017 at 12:50

The simplest way to do this is to paste numbers into a file using an editor e.g.

  $ vi mynumbers.dat

and then start gnuplot and make a scatter plot

 $ gnuplot
 gnuplot> plot 'mynumbers.dat'

This will produce the following image
