Question

I try to make a plot on gnuplot which has no real range order on x-axis.

--------------------->
1 4 2 20 17 12 10 8

It’s therefore not a real function as you would interpret it with math knowledge, but it has some sort of index on its x-axis which has no numbering order and runs from 1-20 but 20 could be the first, or in the middle.. everything may be mixed..
hope you understand what I mean cause I am hoping gnuplot can handle that.

maybe i can write my data file so that point 2 contains the data that should be there on the y-axis and just move the labels around on x-axis?

Answer 1

Solution is using xticlabels and add an extra column in the data file.
ie

#xdata ydata label 
0 2 1 
1 3 14
2 10 0 
3 8 20 
etc. 

command: plot "data.dat" using 1:2:xticlabels(3) with lp"
