I'm experimenting with evolutionary algorithms and I have written two text files that I cannot get the plot. Based on the information on google, I think I have the format correct.

(generation-number) (tab) (best-fitness)

for example:

1 231

2 240

3 245 ...

To plot this, I start gnuplot and I am greeted by the welcome screen. I then type: plot 'ga.txt'

The cursor immediately returns and nothing is plotted.

I am using 64 bit Mint with Mate.

The answer to this problem is to install gnuplot-x11 and to set the terminal from 'unknown' to 'x11'.
