gnuplot - How to display tics only for the values in the dataset?

Question

I have a standard dataset, say:

1,10
2,15
4,20
8,5

Is there any simple way to display tics only for the values in the dataset?

I can manually set them:

set xtics ( 1, 2, 4, 8 );
set ytics ( 5, 10, 15, 20 );

however, this has two side effects:

1. I have to manually find all the values;
2. for some reason, it removes the margines (compared to autoscaling), so I have to compute them manually (set offsets graph works strangely with tics manually set).

Is there any simple way of display the same plot it would be plotted without the set *tics command, with the only difference being the tics printed?

I'm on Gnuplot 5.2.

Answer 1

You can call xtic() and ytic() from the plot command. Eg:

set datafile separator comma
set offsets graph 0.1, graph 0.1, graph 0.1, graph 0.1
plot '-' using 1:2:xtic(1):ytic(2)  pt 7  lc black  title ""
1,10
2,15
4,20
8,5
end
