In the MWE below (a coordinate system having its first axis logarithmized), major and minor ticks misalign. I have tried to figure out which logic for I should apply for the yticksize=0 8 option, but fiddling with this using trial and error only gives me alignment of the minor gridlines - I fail to control the length of the minor and major horizontal gridlines.

          Ox={-4},% Origin for X
          dy=0.2,Dy=5,yticksize=0 8,ysubticks=4,
          Oy={-25},% Origin for Y

Coordinate system, first axis logarithmized - major and minor ticks misaligned!

Thus my question:

How do I control the minor ticklines providing a rightmost (upper) limit somehow in concord with the units of the x-scale?


Shortened \psset{} statement. Changing to yticksize=0 8 solves alignment problem with the major horizontal ticklines.

Added the picture below, corresponding to yticksize=0 7 in stead of yticksize=0 8 (uppermost image). Note that righthand endpoints of the minor gridlines and the major gridlines both move when changing the upper limit of yticksize, but they have different lengths, the major being the longer. enter image description here

    ysubticksize=1 It is a factor, relative to the major lines!

you have 8 units in x direction:

yticksize=0 8,ysubticksize=1,

and the sub ticks should be of the same size.

  • Yes, yticksize=0 8,ysubticksize=1 fixes it. The value corresponding to 8 fixes the alignment issue across my implementations of this. Most obliged. Jan 26, 2018 at 19:37
  • And yticksize=8,ysubticksize=1 works, too. Jan 26, 2018 at 19:47
  • Ahh, when ticks have default size, minor ticks are just that: about 90% -- smaller. The ysubticksize=1 make size of the minor exactly 100% the size of the major ticks. Jan 26, 2018 at 21:37

    see documentation of pst-plot (Table 1) on page 26 for the default value.
