[Gnuplot-info] Exporting a 3D interactive plot

[dpwes <dp...@ho...>]

Hi,

I was just wondering whether there was any way of exporting the interactive
terminal window created with the splot command?

Basically, I have a 3D scatter plot that I'm rotating with my mouse, and I'd
like to send it to someone who doesn't have gnuplot installed.

Is this possible?

does

set macro

scaledata1 = `awk '/Total/ {print $4}' @source`

work?

No.  There would be a way to write a completely new terminal driver, 
aptly called 'curses', to do that, though.  The only question is the 
usual one: who's gonna volunteer?

Re: [Gnuplot-info] lines and points from discrete data

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

so you want to mix the data of the two files, this can be
done by using the pseudocolumn "0":

plot 'data.dat' using ($0*2):2:xtic(1) with linespoints, \
'data1.dat' using ($0*2+1):2:xtic(1) with points

[Gnuplot-info] using gnuplot for monitor plots, i.e. for repetitive plotting

[<lyn...@fr...>]

Hello!


Is  there  a  way to use gnuplot to do monitoring plots, i.e. to do repetitive
plotting?
In other words a "tail -f" that does not print the line but extends a plot  of
the data as new dataset come in?
Say  for  monitoring  the  temperature  of the CPU for the last N measurements
optainted by:
while true; do cat /proc/acpi/thermal_zone/THRC/temperature ; sleep 1; done

Thanks for any help or hints

[Gnuplot-info] coloured dumb terminal similar to wavemon display

[<lyn...@fr...>]

Hello!


I'm looking for a command line plotter. The gnuplot term dumb is basically it but is there a way to make it use ncurses for nicer/coloured plots? Is there a way to generate plots like those of wavemon (http://eden-feed.erg.abdn.ac.uk/wavemon/img/wavemon2.png)?
If not, does anybody know of a utility that could do this?

Thanks for any help or hints

[Gnuplot-info] libgd support threatening gnuplot?

[Keith L. <ke...@kl...>]

List newbie.
I use gnuplot (running on Scientific Linux 5.4) to make lots
of png files.  Gnuplot uses the libgd library for that.

Libgd has received no development since 2007 or so. 
www.libgd.org has been offline for at least a week (when I
started looking for it).  I am concerned that this important
component of gnuplot is unsupported.  As the underlying
dependencies for libgd evolve, it may stop working, and
gnuplot will be crippled.

Hoping to minimize future dependency conflicts for gnuplot,
I tried to compile it statically, but I am not very good at
tweaking configure scripts and makefiles.  All my attempts
produced the normal version, linked to about 30 external
libraries, including libgd.so.2 .  I can probably figure
out a way to copy a working set of these libraries to 
another directory, and recompile for those, but this is
becoming a lot of work to get around a hypothetical risk.
Still, I want to protect my gnuplot (and libgd) investments.

Have gnuplot developers (*) thought about what would happen
if libgd went away?  If the PHP developers (**) aren't doing
anything with libgd, is it time for some other group (hint)
to take over its development?

Keith

(*) ob. praise:  Thank you for your fine work on gnuplot!

(**) ob. sneer:  PHP, the public bathhouse orgy of
programming languages.

(***) ob scold: Shame on me!

Re: [Gnuplot-info] lines and points from discrete data

[BBands <bb...@gm...>]

Maybe I am misunderstanding, but gnuplot offers very powerful control
over tics and labeling. See help set xtics. This is sort of a common
problem in finance where we want trading days to be equidistant, not
calendar days. There is a simple example in my finance demo in the
demos directory.

Thanks to Hans who just pointed out that I wrote my requirements
incorrectly. What I meant was:
"However, I want the xtics to be equally spaced. So, 1000 should be _not_
further from 1200 than 1500 from 1550.

Re: [Gnuplot-info] lines and points from discrete data

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

Hi, thanks very much.

The problem with that solution is that it doesn't meet the following
requirement:
"However, I want the xtics to be equally spaced. So, 1000 should be
further from 1200 than 1500 from 1550."

So, for example, only the tics for 1000, 1200, 1500, 1550, 1600 and
1750 should show up.
Then the line graph for data.dat would have a point in 1000, 1500 and
1750. There would then be 3 points for data1.dat in 1550, 1600 and
1750.

I am sorry if I wasn't initially very explicit.

Cheers,

Looks like you're trying way too hard.  From what you said you wanted, a 
much simpler

	plot 'data.dat' u 1:2 w lp, 'data1.dat' u 1:2 w p

would have fit the bill.

Re: [Gnuplot-info] lines and points from discrete data

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

add the column with the x-values to the 'using' option:

plot 'data.dat' using 1:2:xtic(1) with linespoints, \
'data1.dat' using  1:2:xtic(1) with point

[Gnuplot-info] lines and points from discrete data

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

Hi,

I have the following:
data.dat
1000 5
1500 4
1750 9

data1.dat
1200 2
1550 8
1600 6

I want to plot data.dat as a line and data1 as points.
However, I want the xtics to be equally spaced. So, 1000 should be 
further from 1200 than 1500 from 1550.

I have tried:
set xtics (1000 1, 1200 2, 1500 3, 1550 4, 1600 5, 1750 6)
plot 'data.dat' using 2:xtic(1) with linespoints, 'data1.dat' using 
2:xtic(1) with points

but to no avail.

Any tips on how to get this done?

Cheers,

[Gnuplot-info] xticlabels()

[Juan-Francisco D. <mo...@gm...>]

Hi everybody,

I install gnuplot under CentOS 5.5 using yum. The version installed is :

gnuplot> show version

    G N U P L O T
    Version 4.0 patchlevel 0
    last modified Thu Apr 15 14:44:22 CEST 2004

    This is gnuplot version 4.0.  Please refer to the documentation
    for command syntax changes.  The old syntax will be accepted
    throughout the 4.0 series, but all save files use the new syntax.

When I try to use the xtic() function, gnuplot return:

gnuplot> plot "temp.txt" using 1:3:xtic(2) with boxes
                     undefined function: xtic

The instructions I use are:

gnuplot> set terminal png
gnuplot> set output "temp.png"
gnuplot> plot "temp.txt" using 1:3:xtic(2) with boxes

The question is: What xtic() function doesn't work?

I see that perhaps it's because the package it's not compile with this
option enable but reading the INSTALL file I can't see any option about
tics.

I hope someone can help me with this trouble.

Re: [Gnuplot-info] name of current script

[Robbie M. <ro...@ac...>]

Hello all

First up, thanks Vinod for your suggestion of a bash
wrapper script.

Please note the following corrections: exho is echo,
the OUT assignment (righthand-side) should be in
backticks (`) not single-quotes ('), --persist should
be -persist.

I reworked the original script and tested it on Linux
plus Gnuplot 4.2 patchlevel 6:

--- src begin / bash --------

#! /bin/bash

# usage message (optional)

case "$1" in
    --help|--hel|--he|--h|-help|-hel|-he|-h|"-?")
        SCRIPT=$(basename "$0")
        echo "    usage: $SCRIPT <gnuplot-cmds>   create LOADFILE string
and load gnuplot-cmds file"
        echo "           $SCRIPT --help           show this message and exit"
        exit 0
        ;;
    "")
        SCRIPT=$(basename "$0")
        echo "$SCRIPT: gnuplot file name required (try --help for usage)"
        exit 2
esac

# active code

ARG1=$(basename "$1")                   # adapt these next two lines to
your needs
ARG1="$PWD/$ARG1"
echo "LOADFILE = \"$ARG1\"; load '$1'" | gnuplot -persist

----src end -----------------

And tested it with the following gnuplot code:

--- src begin / gnuplot -----

set title "source : " . LOADFILE        # 'LOADFILE' is set by invoking
script
plot sin(x)

--- src end -----------------

best wishes
Robbie

[Gnuplot-info] Enhance text mode, Symbol &

[Marco <mca...@gm...>]

Dear all,

I'm trying to insert the symbol & in a figure but it seems that this is the only
symbol not allowed.

I tried 

[...]
set encoding utf8 or set encoding iso_8859_1

[...]
plot '../PLOT_MB_data/Igap_diff_He' using 2:1 with points title "{/=14 Adiabatic
ic {\046} bus    }" ls 1

or alternatively
plot '../PLOT_MB_data/Igap_diff_He' using 2:1 with points title "{/=14 Adiabatic
ic {/Symbol &} bus    }" ls 1

but nothing works.

This seems strange to me since all the other symbols I tried (\044 \045 and
other) worked well.
Is it a bug?

Please let me know,
Marco

[Gnuplot-info] typography, usability and design with gnuplot

[Jonas S. <ne...@jo...>]

hi,

i want to generate plots with gnuplot and embed them in LaTeX.
Do you have hints for nice settings, that improve the look?

Do you know standards, i should read?

For example DIN 461 about plots in coordinate systems. 

I want that the plots integrate nice in the text body. So i
have to get same font and line thickness in the plot. 

Do you know examples of very well designed plots?

kind regards,

[Gnuplot-info] clustered bar graphs with yerrorbars

[Navin <rus...@ya...>]

Hi All, 

I have data of the form 

0    C        lower  higher          H      lower  higher
AAA 0.002677  0.0024 0.0028    0.002888    0.0026  0.0030
GGG 0.002677  0.0024 0.0028    0.002888    0.0026  0.0030


I wanted to make a clusted bar plot using gnuplot in which column C and H are
clustered together and the lower and high column are the lower and higher limits
of the yerrorbars. 


I have tried playing around with sample files for clustered bar plots available
on the internet but did not succeed. ANy help would be greatly appreciated. 

Thanks, 

Navin

You should probably start by updating from your rather far out-of-date 
version of gnuplot.  You're almost 7 years behind the bus!  A lot has 
happened since then.

Once that is settled, consider being more specific.  What did you 
actually try, and how exactly was it unsuccessful?

That may not be the right tool for the job.  gnuplot is a plotting 
program, not a data processing engine.  It does offer some data 
processing as an aid for the plotting work, but it's not supposed to 
replace an actual data management tool.

No.  But you can re-define your parameters such that such relations are 
automatically taken care of.

So fit

	f(x)= (a_internal**2-3b) + b * x

then extract the actual a from sqrt(a_internal)
I'll be very grateful for the help.

[vinodkgul <vin...@ya...>]

Hi,

You can use the shell scrip As follows:
1st file--> gnuplot_file_print.sh
exho $1
OUT='echo $1 | cut -d "." -f1'
echo "set label 101 ' Path: `pwd` Filename : $OUT' ; load '$1' " |gnuplot
--persist

say test.gnu is the file containing the plot commands then from prompt use
following :

sh gnuplot_file_print.sh test.gnu
