[Gnuplot-info] restore setting back to default

[Jon <dev...@gm...>]

Dear All,

There is an annoying issue I am faced with, and I would expect a simple
solution for it.

Whenever I use say set xtics ("" 1,"" 2) to change display of xtics, I
don't know how to restore xtics into default setting. Similarly things
apply to say set tmargin etc. Is there way to restore default setting?

I tried to google it, but it does not give back useful results and I thus
have to ask here.

Thanks,

Sincerely,
Jon

[Gnuplot-info] splot fails to use user defined line styles for contour base

[Tony2 <iak...@gm...>]

Dear all,

I have the following problem:
I plot a three dimensional surface using 'splot' and 'set contour base'.
It appears to be that contour lines in the final eps image don't have the
line type that I have pre-defined in my user line styles. So instead of all
contours having lt 1 (solid line) as I have defined, all the contour lines
are dashed, dotted and whatever but solid. (but it looks like for png
terminal everything works fine)
I would be grateful for any help.
Thank you!

Here is the gnuplot script:
****************************************************
set term post eps enhanced color
set output "potential_alpha0.0.eps" 

unset style

set linestyle 1 lc rgb "blue" lt 1 lw 1
set linestyle 2 lc rgb "navy" lt 1 lw 1
set linestyle 3 lc rgb "#9400D3" lt 1 lw 1
set linestyle 4 lc rgb "magenta" lt 1 lw 1
set linestyle 5 lc rgb "red" lt 1 lw 1
set linestyle 6 lc rgb "orange" lt 1 lw 1

set style increment userstyle

a=-3
b=0.25
alpha = 0.0
set xlabel "|{/Symbol y}|"
set ylabel "|{/Symbol f}|"
set zlabel "U(|{/Symbol y}|,|{/Symbol f}|)"
#set hidden3d
set samples 20, 20
set isosamples 21, 21
set cntrparam levels incremental -20,4,0
set linetype 1
set contour base
set xzeroaxis lt 1 lw 2 lc rgb "black"
set yzeroaxis lt 1 lw 2 lc rgb "black"
set xrange [-4:4]
set yrange [-4:4]
f(x,y) = b*(x**4+y**4) + a*(x**2+y**2) - alpha*x**2*y**2
splot f(x,y) ls 2

set output
set terminal x1

Re: [Gnuplot-info] save the current plot as a eps or postscript file

[Thomas S. <t.s...@fz...>]

why do you need 'replot'?
wouldn't it be enough to:

set terminal postscript eps enhanced colour dashed lw 1 "Helvetica" 14 
set output "1.eps"
plot "./ReportDataConvergence.out" u 1:10 w l
set output "2.eps"
plot "./ReportDataConvergence.out" u 1:7 w l
set output

[Gnuplot-info] Function with a jump discontinuity

[Konstantin L. <ko...@ko...>]

Hallo,

I would like to plot a function with a jump discontinuity. I've figured
out that I can use an if-then-else operator. Here is an example:

gnuplot> f(x) = f(x) = (x<2) ? x**2 : 1

This works fine but I don't want a line between those functions.

I hope someone can help me.

Best regards,

[Gnuplot-info] Filling outside of circles

[Tom C. <ma...@as...>]

Hi,

I would like to produce a plot that consists of a few circles, with the
outside of each circle hatched in a different way.  So the intersection of
all the circles has no hatching, and areas that are outside of more than one
circle have more than one hatch.

I've tried experimenting with 'filledcurves', but I can't even fill the area
outside of a single circle.

Is it possible to produce the kind of plot I would like in gnuplot?  Thanks
for any help.

Re: [Gnuplot-info] help with pdf terminal

[Jon <dev...@gm...>]

I would guess that each graph is too small such that the title text cannot
be contained in the key space. Can you remove title (by using notitle with
plot) and see what comes out?

As to landscape plot, I myself never get successful result, maybe you can
let me know when you figure it out.

[Gnuplot-info] help with pdf terminal

[David H. <dlh...@co...>]

Hi,

I'm trying to create a pdf file from gnuplot. I'm using a script that 
uses multiplot to create a 3 x 3 matrix of graphs and would like to 
present the output as one-page landscape pdf file that will print on a 
single  8.5 x 11 sheet. When I run the script I get the following 
message (repeated nine times for each plot in the matrix):

Warning - difficulty printing plot titles into key

Gnuplot outputs a pdf file but I get an error when I try to view it. The 
only terminal command I use is set terminal pdf.

Any thoughts on what's going on?

Thanks

David

It's very hard to make sense of this description if you show neither a

You've changed two things at once: the operating system and the version 
of gnuplot.  How did you arrive at the conclusion that it was the change 
operating system that caused the difference in behaviour?

As to whether dotted curves were any more correct than solid ones in 
that case is impossible for anyone out here to determine, as you didn't 
show that same script you used.

[Gnuplot-info] unexpected feature when drawing with splot on scattered data

[Jon <dev...@gm...>]

Dear All,

I am trying to use splot to show 3D vision on some dataset. But it seems
give unrealistic peaks at the four corners. The command I used is

set dgrid3d 50,50
sp 'fort.88' u 1:2:3 w pm3d

Somebody told me it could be due to the fitting scheme used to interpolate
through the scattered dataset. Is this the case? If so, how could the
interpolation be turned off and use the simplest linear interpolation only?

By the way, if I only use

sp 'fort.88' u 1:2:3 w l

it's able to give all the subtle details of the data, how should I possibly
do to preserve the honest feature of the data, but give myself a better
view using color and contour?

Thank you very much,

Sincerely,
Jon

[Gnuplot-info] Arbitrarily distorted images?

[Craig D. <def...@bo...>]

Dear Gnuplotters,

I'm interested in being able to plot images under arbitrary nonlinear distortions: basically, using the full X/Y info implied by the syntax "with image" with the full (x,y,value) tuple.  Is there a method for doing this (perhaps via splot)?  That ability would be very useful, e.g. for displaying scientific images with the not-so-new-any-more FITS standard for representing nonlinear mappings between world coordinates and pixel coordinates.

Currently I am resampling onto a linear grid and then shipping the rectified object off to gnuplot - but that is very slow and also nonoptimal: for example, I have to guess at a final spatial resolution, because only the gnuplot process knows the inherent resolution of the output stage.

I'm incorporating this functionality into the PDL::Graphics::Gnuplot module for Perl/PDL, but I can't imagine we're the first group to want to do this with Gnuplot.

Thanks,
Craig DeForest

[Gnuplot-info] epslatex linetype always be solid line under wguplot?

[Jon <dev...@gm...>]

Dear All,

I tried to use epslatex terminal to draw dotted curves. The same script and
I run under linux and windows using gnuplot 4.4.3 and wguplot 4.6.0, the
different effects I obtained. Linux_gnuplot gives correct dotted curves,
while windows_gnuplot always gives solid lines.

I am wondering whether this only happens to me or others also met with this
issue?

Thanks,

Sincerely,
Jon

Re: [Gnuplot-info] help on xticlabels behavior

[Jefferson S. E. P. <st...@gm...>]

Hi,

try setting the font as well, e.g.:
set terminal jpeg font "Arial 10"

For me it works. No idea why or if it's general, but I have the same
version of gnuplot as you, so it might be worth trying it out. BTW,
you could consider using png instead, it's such a nicer format.

Cheers,
Stafusa

[Gnuplot-info] help on xticlabels behavior

[Marcos M. <mar...@gm...>]

Hi folks,

I'm having a problem when using xticlabels and I'm not sure how to fix it.
I want to have the x labels rotated by -45 degrees. The problem is that
when I use the command "set xtics rotable by -45" it changes the behavior
on xticlabels and no matter what I do, it never changes. I'm using version
4.4 patchset 3 (on xubuntu 12.04).

The source file has 5 columns and the first one I want to use as label on
the x-axis. The gnuplot commands I'm using are below. If I leave the "set
xtics nomirror rotate by -45", it will always print over the bar (or under
the bars, since it is filled), perpendicular to the x-axis. If I remove the
line "set xtics nomirror rotate by -45", it will then print under the
x-axis, but parallel to it. Rotate in this case doesn't work.

The question is, how do I make the label rotate by -45 using xticlabels? I
tried everything, but the only result I get is the one I mention above. It
will always put the label perpendicular to the x-axis and under the bar.

set terminal jpeg medium
set output "histo.jpeg"
set boxwidth 0.75 absolute
set style fill solid 1 border -1
set xtics nomirror rotate by -45
set style histogram cluster gap 1
set style data histogram
set ylabel "Bandwidth"
set xlabel "Kernel Configuration"
plot "xx.dat" using 2:xticlabels(1) t "1 VM", '' u 3 t "2 VM", '' u 4 t "5
VM", '' u 5 t "10 VM"
show output

Thanks for the help.

Re: [Gnuplot-info] gnuplot stuck at 100% CPU when put in background in a shell script

I used an account using csh and it gets the same behavior, so it looks like there is something about gnuplot in particular that causes this and it's not sensitive to the shell.

Re: [Gnuplot-info] gnuplot stuck at 100% CPU when put in background in a shell script

Almost the same thing happens if I use csh: 

#!/usr/bin/env csh
//usr/local/tools/gnuplot-4.4.3/bin/gnuplot.real 

Very slight differences, but basically hitting control-C then fg in this case still derails gnuplot.  
My login shell is bash, so I suspect that's impacting things even when the script calls csh.

both termianl doesn't supprort the pipe.
 
I run the command:
    gnuplot -p < myplot.cmd
 
where myplot.cmd contains the following
 set terminal qt
 #set terminal wxt
 plot sin(x)

The pipe works fine for x11 or aqua terminal though.
 
I also tried gnuplot 4.7, the pipe works for qt but not for wxt terminal.
However,  the generated plot  in qt terminal cannot zoom and grid button doesn't work.
 
Any suggestions?
 
thanks.

[Gnuplot-info] Bug? print() prints to stderr

[Dr. I. D. J. <die...@t-...>]

Dear listmembers,
in the current gnuplot - version (4.6 patchlevel 0) print () is redirected to 
stderr rather than to stdout - what is IMHO not the way it should be .... 
errors should go to stderr, but intentional "regular" printings should go to 
stdout instead.

Reproducible: always
Expected behaviour: fprintf(stdout <SOMETHING>) instead of fprintf(stderr 
<SOMETHING>)

Thank you for looking into this,
take care

Re: [Gnuplot-info] gnuplot stuck at 100% CPU when put in background in a shell script

[Robert P. <rd...@gm...>]

Spinning on readline when put into the background sounds vaguely
familiar.  To simplify things a bit, what happens in your environment
when you run the following script:

#!/usr/bin/env bash
/usr/local/tools/gnuplot-4.4.3/bin/gnuplot.real "$@"
_value=$?
exit $_value

?

And can you provide a minimal example of the command line args?
