gnuplot: plotting a file with 4 columns all on y-axis

Question

I have a file that contains 4 numbers (min, max, mean, standard derivation) and I would like to plot it with gnuplot.

Sample:

24 31 29.0909 2.57451
12 31         


        

Answer 1

Just to add that you can specify the increment in the for loop as third argument. It is useful if you want to plot every nth column.

plot for [col=START:END:INC] 'file' using col with lines

In this case it changes nothing but anyway:

plot for [col=1:4:1] 'file' using col with lines
