maybe use an external program to omit the blank lines:

plot '< awk "{if (NF) print}" ./data.dat' u (bin($2, 0.2)):(1) smooth frequency

"awk" should be installed on every unix system, for windows systems google
for 'awk windows'.

either by defining some arrows covering the axes:

set arrow 1 from graph 0,0 to graph 0,1 lt 1 lw 2
set arrow 2 from graph 1,0 to graph 1,1 lt 2 lw 2

or by using 'multiplot' with fixed margins:

reset

set bmargin 2
set lmargin 7
set rmargin 7
set tmargin 2

set multiplot

unset xtics
set ytics nomirror
unset y2tics
set border 2 linetype 1 linewidth 2
plot sin(x) axes x1y1 linetype 1 notitle

unset xtics
unset ytics
set y2tics nomirror
set border 8 linetype 2 linewidth 2
plot 2.*cos(x) axes x1y2 linetype 2 notitle

set xtics nomirror
unset ytics
unset y2tics
set border 1 linetype -1 linewidth 1
plot sin(x) notitle

unset multiplot

as far as i know, no

this 'point' should be a 3-dim object, you could simulate this
by placing little 'plots' where you want to have cubes:

datafile.dat:

-1 -1 -1
-1  1 -1
-1  1  1
-1 -1  1
-1 -1 -1

1 -1 -1
1  1 -1
1  1  1
1 -1  1
1 -1 -1

plot script:

set xrange [-10:10]
set yrange [-10:10]
set zrange [-10:10]
splot 'datafile.dat' using 1:2:3 with lines linetype 1, \
'' using (0.1*$1+1.):(0.1*$2-2.):(0.1*$3+2.) w l lt 1, \
'' using (0.5*$1-3.):(0.5*$2+2.):(0.5*$3-2.) w l lt 1

It's gnuplot... it's not GPL-licensed, and there is no connection to GNU/FSF except the unfortunate coincidence of naming. (There's a FAQ about how the name gnuplot came to be, if you're curious.)

Yes... see the "Coloured axes" section near the bottom of http://gnuplot-tricks.blogspot.com/2009/05/gnuplot-tricks-many-say-that-it-is.html for an example.


> 2) Suppose I plot points in a 3D graph. Is there a point type representing a small cube, similar to the small square existing for 2D graphs? (I know a small square is possible in 3D, but I don't really like it.)

You can see all the point types for a given terminal with the 'test' command. As far as I know, there are no solid, 3D point types.


> 3) Suppose I plot points using crosses. Is there a way to change the thickness of the lines of the cross?

That is controlled via linewidth. If you want the line itself and the points to be different thicknesses, you'll have to plot the same data as points, then as a line. For example, "plot 'file.dat' with points lw 3, '' with lines lw 1" or see 'help linewidth'.

[Gnuplot-info] axis color, point type & point thickness

[Martin G. <mg...@lb...>]

Dear GNUPlot:

I have three questions:

1) Suppose I plot on the same graph a first curve using one color and axes xy1, and a second curve using another color and axes xy2. Is there a way to have y1 axis, tics & label of the same color as the first curve, and y2 axis, tics & label of the same color as the second curve? (Actually, by hand I know how to do the label and tics…but the axis?)

2) Suppose I plot points in a 3D graph. Is there a point type representing a small cube, similar to the small square existing for 2D graphs? (I know a small square is possible in 3D, but I don't really like it.)

3) Suppose I plot points using crosses. Is there a way to change the thickness of the lines of the cross?

Many thanks in advance for your precious help.

[Gnuplot-info] Broken histograms when using smooth frequency on data file with discontinuities

[David L. <lin...@ie...>]

Hello,

I would like to plot the distribution of a variable and I follow the
directions given in the "Gnuplot in Action" book:

I define a binning function:

bin(x,s) = s*int(x/s)

And then I use the plot command:

plot './data.dat' u (bin($2, 0.2)):(1) smooth frequency

However, the 'data.dat' file has a number of discontinuities in it
(i.e. blank lines). This causes the output to show several sets of
histograms, one for each continuous set of data.

Is there any workaround for this? I would like the histogram to show
the distribution in the whole file, and to ignore discontinuities.

Thanks in advance,

Re: [Gnuplot-info] gnuplot 4.5 wxt format not working

[Tatsuro M. <tma...@ya...>]

Hello

I have found the web page written in Japanese about wxt terminal on windows.

Please try to add the below

bind "Close" "if (GPVAL_TERM eq \'wxt\') exit gnuplot; else exit"

in the top of the your gnuplot script.

I have not tried myself so that I do not know the above will work or not.

[Gnuplot-info] gnuplot 4.5 wxt format not working

[bluebluesky <one...@ya...>]

Hi,

I just tried gnuplot 4.5 latest build,

For the attached two files plot.c and plotcm2 below,
/* Filename: plot.c */
#include <stdio.h>
int main()
{
    system("wgnuplot.exe plotcmd2 -");
    return 0;
}

#Filename: plotcmd2
set terminal wxt
plot [-10:10] sin(x)


When plot.c is compiled and executed in Windows,
a plot using terminal wxt will appear correctly.
But, when the plot window with a graph is closed by clicking
the 'x' on the upper right corner, the process wgnuplot.exe still
runs in the background.
How to make change to the program so that 
the plot window is closed, the process for wgnuplot.exe 
will also be closed?

BTW, if wxt terminal is changed to windows terminal,
wgnuplot.exe will be closed correctly. also, I  will not be able to use
pgnuplot.exe due to my GUI app.
thus, I want to see if it can work out with wgnuplot.exe

Thanks in advance.

a column is plotted without the 'matrix' option
using the line number and the data position (here:
the 5th entry, counts from 1) in the input line:

plot ... using 0:5

a row is plotted with the 'matrix' option using the

a specific data block (here: 5th line, counts from 0):

plot ... matrix using 1:3 every :::4::4

use an up-to-date version of gnuplot and store the 'old' value to a variable

plot 'datafilename' using 1:(temp=$2-y_old , y_old=$2 , temp)

Re: [Gnuplot-info] timefmt skip one data in format

your example data set doesn't contain the weekday.

nevertheless, you may skip the weekday (if it's numerical) by reading it as
e.g. month and overwriting it with the right month information afterwards:

set timefmt "%Y,%m,%m,%d,%H,%M"

Re: [Gnuplot-info] Plotting 3-dimensional tree

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

splot 'datafilename' with lines

should work, but let one data block (separated by one blank line) have more
than two points otherwise you will get cross isolines.

to have branches in different colors you should divide your data into
data sets (separated by double blank lines) and use the 'index' option
of the 'splot' command.

Re: [Gnuplot-info] epslatex and texfolders

[Patrik.Br. <pat...@gm...>]

Hello,

I solved the problem by generating standalone latex files and then eps
figures from the latex file. Use the following terminal:

set terminal epslatex standalone color

and the simply letting latex make a .ps file from that .tex-file. Include
the .ps-file like any other eps figure into you latex document.

I use Notepad++ which lets you run batch files that I have configured to do
all this automatically for me (including generating a pdf file at the same
time) using a shortcut. Very convenient. (I use windows)

[Gnuplot-info] Plotting 3-dimensional tree

[karlahund <kar...@we...>]

Hi everybody,

I'm trying to plot a 3-dimensional tree with thousands of branches. The
dataset looks like this:

startpointX startpointY startpointZ (new line)
endpointX endpointY endpointZ (new line)
(empty line)
otherStartpointX ...

The start- and endpoints should be connected by a line (so it's gonna look
like a tree at the end). One day it'll be important that some of the
lines/branches have different colors. 
I'm pretty new to gnuplot, so please excuse this probably easy question. 

Thanks in advance! Regards,
Karl

[Gnuplot-info] Possible to specify marker face color and marker edge color?

[Patrik.Br. <pat...@gm...>]

Hello, 

I have been working with Matlab alot, and plotting with Matlab has one
advantage; markers. Gnuplot gives me much more control, but there is one
thing I haven't figured out how to do yet, maybe someone knows. (I think
octave can do this too and since it uses gnuplot I figured it should be
possible)

I want to specify markers (points) with one edge color and another face
color. It is quite similar to the hollow markers that are found in gnuplot,
but without the transparent face/center. 

I have solved it by using two point types, like the following, but that
messes up the legend. Is it possible to define new point types as
combinations of existing point types? 

http://old.nabble.com/file/p32765413/mwe3.png 

reset
set terminal pngcairo size 200,200
set output 'mwe3.png'

set format x ''
set format y ''

# Line type with blue filled round markers
set style line 1 pt 7 lc 3 lt 1 ps 1

# Line type with light blue filled round smaller markers
set style line 2 pt 7 lc rgb "#abcdef" ps .6

# Plot same data twice with different point types
plot 'data.dat' using 1:2 with linespoints ls 1 t '1',\
	 '' using 1:2 with points ls 2 notitle
	 
unset output

data.dat:

1.0000    1.0000    1.7062    9.9417
2.0000    3.0000    3.7585    8.2323
3.0000    5.0000    5.4395    2.5743
4.0000    7.0000    7.3054    0.0440
5.0000    9.0000    9.7473    2.0102
6.0000   11.0000   11.6045    2.4656
7.0000   13.0000   13.1175    7.4214
8.0000   15.0000   15.3401    0.5689
9.0000   17.0000   18.8288   11.9895
10.0000   19.0000   19.9611    14.3540

Re: [Gnuplot-info] Problems with errorbar and border

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

you could download the gnuplot sources and change/add a few lines in
'graphics.c'.

the following patch is for the development version of gnuplot:

[Patrik.Br. <pat...@gm...>]

Hello, and thank you for the answer. Unfortunately I have a grid with a
dashed grid line at the top, and I don't want to hide that. I don't want to
set the grid in front of the errorbars either because that looks a little
strange for the other data.
