[Gnuplot-info] Some basic questions on tics and labels

[Paulo J. M. <poc...@gm...>]

Hi all,

I'm trying to plot some points in a cartesian plane. The points are in
a file and I have the following:
set terminal x11 # Set terminal (output type)
set logscale xy # Set logscale on xy
set border 3 # Remove right and top borders

set xlabel "X"
set ylabel "Y"
set size square
set style data points

unset label
unset y2tics
unset my2tics
unset x2tics
unset mx2tics

plot [0.01:3600] [0.01:3600] 'data.dat' using 2:1, x


1. Although I have a logscale plot I would like it to show 0,0 as
original instead of 0.01, 0.01. Can I do this?
2. I have removed right and top borders but still there are some wierd
tics that are still there. Even after those unset tics (which don't
seem to affect the tics at all). How can I remove them?
3. There are two labels, one for the points and other for the x
function which I would like to remove, how can I do that?
4. What's the best to include in latex? latex terminal or epslatex terminal=
?


Thanks in advance,

Not automatically --- nor should you want to.  Why do you want to lie to 
the reader of your plot?

Those are not the x2 and y2 tics, which you did remove.  They're the 
mirrored x and y tics:

	set xtics nomirror
	set ytics nomirror

Read "help plot" about the "title" option.

Almost always epslatex.  "latex" is a fall-back for special or desparate 
cases.

Not a lie... Just thought that a graph starting at 0,0 would look nicer. :)

notitle is nice! :)

Thanks, yet, 2 questions:
1 - I don't have my figs in the same place as the latex files so when
including I get a path problem in the generated tex file by gnuplot
which assumes the eps are in the same path of the latex main files.
Not a problem at all, I just manually change the generated tex but is
there anyway of doing this from gnuplot?
2 - How can I change the Latex letters? generated by the tex file? I have:
set terminal epslatex color solid "default" 8
But changing 8 from 10 doesn't seem to change the size at all.

Is it this? Or is there any other way?

Thanks,

Paulo Matos

It wouldn't look nice, it'd simply look *wrong*.  Labelling that tick 
with "0" means you, the author of this diagram, claim that this is the 
zero is on this axis.  But that's not the case, so this claim is quite 
definitely a lie.

No. But you don't have to: LaTeX has path search mechanisms to find 
files.  Use them, and you won't have to edit generated TeX fragments.
Or, if you really don't want to have two files, see the documentation of 
epslatex (or pslatex) on how to make it put the PostScript stuff 
directly into the TeX file.

IIRC, it's not supposed to. Font "default" means the figure will use 
whatever LaTeX's font is at the point of inclusion.  I.e. you can change 
this in the master document, at the point where you include the file 
generated by gnuplot.  You really have to read the documentation more.

Thanks! :) I would love to really have more time to read the
documentation carefully but right now I'm quite in a hurry. I
appreciate your comments.
