#1424 — user defined xtics and mxtics

Dear All

I read in the Gnuplot info's, that when I define my own xtics, I can not
use mxtics, which makes sense.  However, especially in LaTeX terminals,
it is sometimes needed to redefine the axis label (actually only the
label and not the tics).  Is it somehow possible to define xtics and
mxtics the usual way but then change only the axis label, leaving the
tics as they are?  E.g., in Matlab you have two arrays defining the
tics, one with the numeric data and the other with the label strings.

Thanks!
Fab

That's not quite right.  You can define both tics and mtics manually.
But you cannot define tics and have the program insert mtics automatically
between them.

Certainly.
   set xtics ("One" 1, "Two" 2, "Three" 3)
   set xlabel "My favorite label"

But maybe you are asking something else?
For LaTeX output you often want to set a LaTeX format for the tic labels:
   set xtics format "$%g$"

That is also possible, so long as both arrays can be read from the
same file:

   plot <my-real-plot>,  'labeldata' using 1:xticlabels(2)

where the file labeldata contains
1 "One"
2 "Two"
3 "Three"
...

Indeed, I was not precise here!

My problem is the following: I have a plot with log x-axis.  When I use
the format specifier for scientific notation, LaTeX will typeset this as
such (with the e-01, etc. notation).  However, I would like to have xtic
labels like $10^{-1}$, hence I set them manually.  But, for a log plot I
would also like the minor xtics to indicate the scale between the
decades.  But I can not use xmtics in this case.  Do I also have to
create an array for the minor xtics?  I would like to have the xmtics
with half the ticlength of the major xtics.  How would you do it?

Thanks for this input!

  set format '$ %.2t10^{%T}$'

  set tics scale 1.0, 0.5

Does gnuplot now really support manually defined tics and mtics?

So, how do you define the manual mtics here? As far as I remember, this 
has not been possible until recently (unless you use arrows for this, of 
course).

Best wishes,
Ingo

So far as I know it has always been possible to define minor tics.
However, no associated text label is drawn for the minor tics.

Labeled major tics at 0, 0.5, 1.0,  unlabeled minor tics at 0.25 and 0.75:

   set xtics ("Zero" 0 0, "Half" 0.5 0, "One" 1.0 0, 0.25 1, 0.75 1)

The form for each tic is ("Label" <position> <level>)
where level 0 is major tic, and 1 is minor tic.
Both the label and the level are optional.   

Levels > 1 are currently treated exactly the same as level=1 
(label is not printed, minor tic is drawn) but in the future may have 
some different treatment.

Dear all,

I  can't show the minor tics with the following script; however if I comment the lines for xtics and ytics the minor tics appears without problem.

Thanks in advance for any help,
