Grid lines in logscale

[Martijn Kuipers]

Hi,

I am trying to set the gridlines of a plot with a logscale. If I use
semilogy(X,Y), with a range for Y between 0.01 and 1, then I only see a
horizontal gridline at 0.1. I would like to see gridlines at
0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4,
0.5, 0.6, 0.7, 0.8, 0.9, 1

I have tried to play around with set grid mytics, but to no luck.

Sorry if it has been asked before, but I can't seem to get it right.

Thanks for your time,

Martijn

see 'help set xtics'
something like this:

set xtics (.01, .02, .03, .... ,.8,.9,1)

^^^^^^^^^^^^^

Context breach? There's no such command or concept in gnuplot.

Hmm.... then why does

set log y
set grid ytics mytics
plot [0.01:1] x

work quite nicely, here (using gnuplot-4.0.0 on Linux), I wonder?

What part of the results of `set grid ytics mytics` is unsatisfactory?
It does exactly what you [say you] want, although you should be sure
to issue `set mytics default` beforehand. You should, of course, make
sure you're using gnuplot 4.0.

I gues I was trying to hard to use specify the spacing of the gridlines,
like
set grid mytics <value>.

And yes, you're right I use semilogy in octave, mix up from my side.

Now it looks so simple, that I can't tell you what I did wrong. Except maybe
misinterpreting both the help and manual. Thanks for your response.

All it needed was a:
set grid ytics mytics

or from octave
gset grid ytics mytics

P.S. Now I feel stupid. Oh well, better get used to that feeling. GNUplot is
awesome.
