Plot one-dimensional list of points in gnuplot

Question

I have a file with numbers:

1
4
9
...

I want to plot a depencency of the numbers from their order position in the file (points [(1,1); (2;4); (3; 9); ...]).

How can I do it with gnuplot?

Answer 1

Try this :

plot "filename.txt" using ($0+1):1

$0 is the index of entries but it starts at 0 so we simlpy add 1 to it.

Tell me if this works for you!
