Hi, I have this data file : Total time 1845 1064 1056 etc. I plot it using: set terminal svg size 1024,768 set title 'test' set xlabel 'try' set ylabel 'Time (sec)' set style data histogram set style histogram clustered gap 1 set style fill solid 1 noborder set xtics scale 0 plot ARG1 using 1:xtic(1) title columnheader So I get the plot. My question is: how do I display 1, 2, 3, etc. e.g. the line number on the x axis instead of the values ? I tried various things without success. I can add a 1 2 3 column and read from it but I'd like to avoid it.
