I am trying to understand what you want to do: You are asking for
separate mxtics scales for each sample, or an mxtic for each data point?

Both should be possible with some external processing and then writing
the tics as arrows where ever you want. A similar thing has been done in
this plot on Wikipedia (although it might have been made with a special
software):

Here, the oblique tics and mtics of the color temperature must have been
made by lines with given slopes, and I succeeded to reproduce a similar
plot with gnuplot using arrows.

Your task sounds much simpler since you only need vertical small arrows
placed on the x axis or some parallel axis, and positions defined by
your data. I have also written some algorithm to estimate the
appropriate number of partitions of the tics intervals. As an example:
If the xrange has a width of 10 units, than one might want xtics at 0,
2, 4..., and set mtics 4 (i.e. at 0.5 intervals), but if xscale covers
20, then xtics at 5-intervals and mtics at 1,0-intervals (i.e. set mtics
5) might look better. The algorithm outputs a gnuplot code fragment that
contains the set *tics, set m*tics statements and can be loaded by a
driver script. Two axes could be set this way using both x and x2 axis,
but more than two simultaneous x axes, or tics positioned in some
irregular way (see the color space plot above) would require them to be
drawn as arrows.

If you mean something entirely different, could you please give an
example (maybe ASCII drawing or even a scanned hand drawing or so)?

HTH,

Ingo
