Thanks for the hint with the color. In my script I had concatenated x, y, z in
the wrong direction such that size(color,1) was not the same as size(x,1).

I don't get the errors due to an empty color spec though.
Strangely on a different computer I sometimes still get the gnuplot errors.
Could it be there is some check missing about the color vector fitting to  the
data?
It  would  be nice if the gnuplot error were more meaningfull to help find the
cause for it.


I couldn't get the hg sources compile because my autoconf is 2.59 and lowering
the requirement in configure.in caused configure to be unhappy about  my  g77.
Since  I  for  now  I  don't need them I'll wait for a new release including a
configure already.

Thanks for the help

[Gnuplot-info] broken gnuplot pipe with coloured scatter3 from octave

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

Hello!


Because the thread below says it's a gnuplot issue I post this here as well:

In octave I'm having troubles with coloured sactter3. If I do:

x=rand(100,1)
y=rand(100,1)
z=rand(100,1)

scatter3 (x, y, z); 
scatter3 (x, y, z, [], 'b');
scatter3 (x, y, z, z);
scatter3 (x, y, z, 50);
all is fine (just the spotsize is not changed) but with:

scatter3 (x, y, z, 50, [], 's');
scatter3 (x, y, z, 50, []);

 I get this multiple times:
gnuplot> 0.148456192084311 0.601135888459943 0.284623384973014
         ^
         line 400: invalid command


gnuplot> e
         ^
         line 400: invalid command

with:

gnuplot_binary ("tee octave.gp | gnuplot ");

I get:

tee: standard output: Broken pipe
tee: write error

and some time later the gnuplot errors again.

Same problem with:

cat octave.gp | gnuplot

Inside gnuplot:

load "octave.gp"

 "#000000"lc rgb "#000000"lc rgb "#000000" ;
                                                                                                                         ^
         "octave.gp", line 3088: duplicated arguments in style specification


There's a thread about some similar issue:
https://www-old.cae.wisc.edu/pipermail/bug-octave/2007-May/002308.html
assuming it's a gnuplot problem but since the other scatter3 commands work I'm not sure about that.
I also sometimes get a proken pipe error when quitting less showing the 100 random numbers.
I've octave 3.0.5, gnuplot 4.3 patchlevel 0, LFS
octave.gp.bz2 is attached. I wonder why there are so many splot commands in it. It seems to me it's supposed to plot the data mutiple times.

Many thanks for any help or hints.

Re: [Gnuplot-info] Angstroms symbol in Gnuplot

[sgiani <sam...@gm...>]

Dear Thomas,

thanks a lot for the suggestion, it pointed me towards the good direction, I
am satisfied of the result but there is still something I can't understand.

First of all I would like to point out that in your example,


> set xlabel 'Wavelength (\305)'
> 
the "\305" should be between brackets "{\305}"

The rest of the problem, as much as I could deduce, lies probably in the
type of font one uses: in facts I would like to use LaTeX font cmr10.ttf,
and it seems iso_8859_1 encoding it is not totally supported.

I tried to experiment some of the characters listed on the standard
(http://en.wikipedia.org/wiki/ISO_8859-1) within the
> set term png enhanced font "cmr10"
settings

For some amongs them I get the corresponding glyph (as they are called in
the jergon ;-) ), but for others just an empty square box. I tried also the
usual Symbol.ttf font but same story.

Hereafter i post a possible workaround, mixing the font that I desire for
labels (cmr10.ttf) and another that allows me to display the Angstrom
caracter \305 (luxirr.ttf):

> set term png enhanced font "cmr10"
> set xlabel 'Wavelength ({/luxirr.ttf \305})'

Greetings from Switzerland, the land of the constructive compromises! Sam

instead of 'title' just use 'label'.

for terminals with 'enhanced' option you could use
'{/Symbol \136}'

Re: [Gnuplot-info] Angstroms symbol in Gnuplot

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

you don't need a special file.
define GDFONTPATH and then give the filename
(without extension) as font name when setting the
terminal to png.

an example:

i want to use luxi roman regular, the font file is there:

/usr/share/fonts/truetype/luxirr.ttf

in the shell i set:

export GDFONTPATH=/usr/share/fonts/truetype

and in gnuplot:

set encoding iso_8859_1
set xlabel "Wavelength (\305)"
set term png enhanced font luxirr
set output 'test.png'
plot x
set output

Re: [Gnuplot-info] How to install/start gnuplot in vista

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

there should be a file named 'README.Windows' in this folder, with
the information how to install.

the executable files are in ....\gnuplot\bin

Re: [Gnuplot-info] how to draw a sphere that looks like a round sphere

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

oh, what's that?
seems that there is an offset somehow reciprocal to the axis length.

this simple example shows the problem:

set view equal xyz
set xrange [-0.2:0.2]
set yrange [-1:1]
set zrange [-1:1]
splot sin(x**2+y**2)

has to do something with the calculation of 'xcenter3d', 'ycenter3d'
and 'zcenter3d' in 'graph3d.c'.
i'll try to find out how it works...

Re: [Gnuplot-info] how to draw a sphere that looks like a round sphere

[Zhong R. <re...@uc...>]

Thank you Thomas,

It works well for me.  One additional question: how does
gnuplot decide the rotation center of a 3D object?  For
example, if I do 'splot 0.2*cos(u)*cos(v), cos(u)*sin(v),
sin(u)', the 3D oval swings from one side of my window to the
other when I rotate it.  If I do 'splot 0.1*cos(u)*cos(v),
cos(u)*sin(v), sin(u)', the object swings in and out of the
window.  Can I specify a rotation center?

Re: [Gnuplot-info] gnuplot graph setup help

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

set xdata time

it makes no sense to plot 'Date' and 'Time', these values are on the x-axis.
and, plotting a string ('Name') makes no sense, too.

more information you can find in the manual:

or use the 'help' command within gnuplot:
help timefmt
help set xdata

Can you advise how can we plot them in 2d ( probably with time in x axis and
data in y axis ) .


Thanks

Re: [Gnuplot-info] 3d plot with color dots

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

if you are able to generate a rbg-value from the data in the 4th column,
then it can be done:

[Gnuplot-info] how to draw a sphere that looks like a round sphere

[Zhong R. <re...@uc...>]

The sphere I draw in parametric mode looks flattened in z
direction, even I use 'set view equal xyz'.

I managed to use 'set view equal xy' and 'set view' to change
scale and scale_z.  My sphere is now close to round.  The
problem is that its vertical size keeps changing when I spin
the sphere or resize the window.

Could someone give a hint?  There must be a simple option to
make a sphere a perfect sphere no matter how you look at it.

Re: [Gnuplot-info] Plot questions

[joachim h. <jh...@jo...>]

Yes, no problems with Unix commands on OSX. It was a bit complicated,  
because I have the line number as a variable which is changing in a  
reread loop after pausing a while. I got this with (the variable "a"  
is the line number)
command = sprintf("head -n %d $myfile | awk '{print $1}'", a)
zeit = system(command)
Now I could say
print zeit
and the first column of the line is printed in the Terminal window.
When I tried to see this in the plot window with
set label 1 zeit at ...
or
plot ... title zeit
it prints indeed, but it doesn't overwrite the previous print when the  
plot is reread. Instead it prints the values one under each other. I  
don't know if this can be achieved?

Thanks again -

	joachim

Re: [Gnuplot-info] X2-axis labeling for Splot

[M. S. <mir...@gm...>]

Yes, yes, I am aware of this feature mentioned in the documentation,
nevertheless I actually hoped that the axes could be hidden by the object
being plotted.

It is probably not common in scientific use but it could look pretty just
for visualisation needs.

For example, I have tried to produce following figure using gnuplot:
http://www.nabble.com/file/p23659362/img.gif 

The sphere could be coloured using pm3d and the axes are shown just for
comparison and demonstration of the corresponding dimensions.

So, I suppose according to your reply that there is no way how to achieve it
automatically? I mean without the need to e.g. simulate the axes by "set
arrow" command and place the labels and {x|y|z}tics by hand...

Re: [Gnuplot-info] Plot questions

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

you could read in the 1st column on a per-line basis
using unix (do these exist on a mac?) commands:

s=system('head -n 1 datafilename | tail -n 1 | awk "{print \$1}"')
or
s=system('head -n 2 datafilename | tail -n 1 | awk "{print \$1}"')

you read up to the line you want to get the data from (head),
then you take the last line only (tail), and extract the 1st value (awk).

then you may use the variable 's' for setting a label
set label 1 s at .....
or setting the plot key
plot 'datafilename' using ... title s ...

Re: [Gnuplot-info] Plot questions

[joachim h. <jh...@jo...>]

I'm not sure how complicated it will be to upgrade to 4.3-cvs. I'm on  
OSX and had some difficulties to install gnuplot. Compiling from  
sources gave some errors I didn't understand, so I went to the  
darwinports. This worked, but I'm not sure if I can install 4.3 via  
Darwinports.
For the moment it would be sufficient to print my first column in the  
Terminal window. Can I do this with gnuplot 4.2? I tried 'print $1'  
but this doesn't work.
Thanks -

[Gnuplot-info] Border issue

[M. S. <mir...@gm...>]

Hi, I have examined recently following simple sequence of gnuplot commands:

set ticslevel 0
set border 31
splot [-1:1][-1:1][0:2] 1

According to the documentation, only the bottom and left vertical border
lines should be displayed but the resulting graph contains also some
fragments of the other three vertical border lines.

Is there any way how to get rid of them? It seems that the "set border"
command has no effect on it at all except the "set border 0" case.

Re: [Gnuplot-info] X2-axis labeling for Splot

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

there are no 2nd x and y axes for 'splot', see
http://www.gnuplot.info/docs/node67.html

x2tics and y2tics don't make much sense, they would be hidden
by the object plotted.
and, in order to have the axis tics and labels visible all the time,
the tics are always drawn at the axes which are in front.
depending on the viewing angles - e.g. for a plot rotated by
180° - these may be the 2nd axes.

Re: [Gnuplot-info] Plot questions

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

the caret is below the 1st 'y' of the 'title my_key', isn't it?
i can reproduce this behaviour here with gnuplot 4.2.

sorry, i forgot to mention, you need gnuplot 4.3-cvs. version
4.2 doesn't have those the operators '=' and ',' in expression
syntax. you need to upgrade to version 4.3.

Re: [Gnuplot-info] Plot questions

[joachim h. <jh...@jo...>]

Thanks. 'unset colorbox' does its job. But with you suggestion  
regarding getting a data value as a key I get the following:

gnuplot> plot "/Joachim/ShellSkripte/00gnuplot/Ganze1_12pms.txt"  
every ::1::1 using (my_key=sprintf("%d",$1),0/0):(0/0) notitle, "/ 
Joachim/ShellSkripte/00gnuplot/Ganze1_12pms.txt" every ::a::a using  
3:2 with imp title my_key linecolor palette frac 0, "/Joachim/ 
ShellSkripte/00gnuplot/Ganze1_12pms.txt" every ::a::a using 6:5 with  
imp title my_key linecolor palette frac .333333, "/Joachim/ 
ShellSkripte/00gnuplot/Ganze1_12pms.txt" every ::a::a using 9:8 with  
imp title my_key linecolor palette frac .666666
                                                                                            ^
          "/tmp/gnupl005512.txt", line 7: ')' expected
(no newlines in the terminal output; just in this email)

Am I doing something wrong?  No idea which ')' I am missing.

[Gnuplot-info] X2-axis labeling for Splot

[M. S. <mir...@gm...>]

Hello,
I am currently trying to figure out how to set a text label together with
tics labels for the second x/y axis in the case of a three dimensional plot
generated by splot. Of course it could be done manually using e.g. the "set
label" command but I would prefer some more systematic solution.

Any suggestions?

Thanks in advance
