xdtics

The set xdtics commands converts the x-axis tic marks to days of the week where 0=Sun and 6=Sat. Overflows are converted modulo 7 to dates. set noxdtics returns the labels to their default values. Similar commands do the same things for the other axes.

Syntax:

      set xdtics
      set noxdtics
      show xdtics

The same syntax applies to ydtics, zdtics, x2dtics and y2dtics.

See also the set format command.
