gnuplot development

Hi,

I'd like to call wgnuplot from C#.  First I made a file by using
"save" command.  That file has some commands for wgnuplot.

Next I wrote the C# code as:

Process.Start("wgnuplot.exe", "load 'command.gp'");

But it doesn't show me anything.
Does anyone has idea?

As a reference, I could call wgnuplot by the code:

Process.Start("wgnuplot.exe");

I would like to let wgnuplot do the sequence of the command.


I asked this question to the gnuplot people, not .NET people (yet)
because I think the command of DOS window will work for
Process.Start() function of C#.

>From DOS window, if I type:

wgnuplot.exe, load 'command.gp'

but this also doesn't work.  So I guess if I could know how to type in
DOS window to make wgnuplot do some commands, I also could call the
above C# command.  If anyone has an advice, please let me know.

Thank you very much,

Koto

Im having 2 problems. First, when gnuplot starts (Windows), it comes up in
Terminal font, and I have to change the font to Courier New so that I can
read the screen. Is there some way to save this setting as the default?
Second, im having trouble in the plot command with trying to figure out
where the file is expected to be. I have tried my documents, the directory
where the bin file is located, C:, others with no luck. Is there a way to
determine where it expects to see the data files, or is there a way to
provide a full pathname to the data file?
Thanks,
Ron

Hi,

I don't think you want to use set size square. If I've
understood you correctly all you need to do is to make
sure that your plot ranges are all the same. Go
through your data and find the largest ranges in x, y
and z and set these values for all plots using set
xrange. 

Hope this helped,

Gavin.

Hi,

Thanks for your work with this very nice tool.
Here I have checked some links, can you update your site or

On the "Gnuplot pages in French" section of page:
http://www.gnuplot.info/help.html

the link to: Gnuplot, traceur et grapheur: tutorial et traduction de  
la documentation de gnuplot 3.7.1;
http://logiciels-libres-cndp.ac-versailles.fr/gnuplot/
sould be
http://logiciels-libres-cndp.ac-versailles.fr/article.php3?id_article=70
Moreover there is no documentation translation, so the link should be called:
Gnuplot, traceur et grapheur: tutorial de gnuplot 3.7.1;

the link to: Gnuplot, LYX et LATEX: une bonne introduction
http://lea-linux.org/cached/index/Software-gnuplot3.html
should be
http://lea-linux.org/cached/index/Software-soft_texte-gnuplot3.html

the link to: Du bon usage de gnuplot: une large introduction
should be specified to: Du bon usage de gnuplot: une large  
introduction (gnuplot 3.6)

the link to: Traceur des fonctions en C++ avec gnuplot: Premiers pas  
avec gnuplot et plus
http://www.univ-pau.fr/Artouste/fr/composants/gnuplot/ManuelutilisateurGnuplot.htm
is dead. I did not find where this page went. I guess it is to be removed.

Hi,

I am drawing several plots like this:

set palette
set pm3d map
set size square
set terminal png
splot "plotXX.data"

Where XX is sequence number. Output are png files.

I would like to have the images of same size and to have the plots (map area)
same size as well, with exact position inside the image? In other words, I
would like to put the images into a sequence and create kind of animation. For
that I need the map to of the same size and on the same position in each
"animation frame".

Thanks for any hints,

Hello,
 I am working on a scientific paper and I have started plotting my data
using gnuplot.

I have come to a point where I don't know how go on. Neither in your nor in
other FAQs I found a clue to my problem:

I want to plot different exponential decay-curves (from
1H-NMR-Measurements). The data curves start from different data points and
decay nearly exponentially to zero. 
It is useful and common in this problem to normalize the curves to the first
data point, i.e. to divide every y-value by the first y-value. By doing
this, one gets exponential curves which start at y==1 and decay to y==0.
This is helpful because only the shape of the decay-curve is interesting,
not the absolute value.

One simple solution would be to type "using $1:($2/DP1)" where DP1 is a
variable formely defined as value of the first data point.
Unfortunately this doesn't help me, since I have more than 300 files to plot
and it has to be done in an automatic way.

Is there a way to read a certain value out of a set of Data (e.g. column 1,
row 1)?
Is there a different way to normalize the curves to the first data point?

Thank you in advance for your help.

Hi,

I want to create graphs for my homework assignment.  I have vectors in 
component form (ex. <0,1,0>).  I want to show 3D vectors by themselves, 
but I can't figure out how to do that.  I tried looking at 
arrowstyle.dem, but I don't understand how it works.

This is what I can do:

gnuplot> set arrow from 0,0,0 to 1,0,0
gnuplot> splot x

Now I can see the vector that I want, but the only way I can show it is 
by graphing an arbitrary function, which is not what I want. 

Also, the axes are shown at the sides of the graph instead of at the 
origin. 

My questions:

1) How can I show my vector(s) alone?



2) How do I make the axes show as the X-,Y-, and Z-axes (instead of 
showing at the edges of the graph)?



Thanks,
Michael

Hello,

I run with Windows XP SP2, I've installed the windows version og =
Gnuplot, but the text in the windows commands line is unreadable : bad =
policy, bad size; how can I modify that? I was looking for a =
WGNUPLOT.INI file, but no one to find!
Thanks for your help,

Is there any way to stop using gnuplot from using Helvetica font for line
labels when generating eps (apart from editing the output!) This causes a
freeze-up when you try to place a gnuplot eps file in Illustrator. The only
workaround I know of at present is to open the file explicitly and copy and
paste but this is a bit of a pain.

Hi,

I am using Gnu Plot 4.0 under WindowsXP.
I want to plot each group of data points in a data file with different
point style, but I don't know how to.
I've seperated each group of data points with double blank lines
according to the manual, but it seems doesn't work.
Please somebody help!

I downloaded gnuplot 4.1 from the repository, but as soon as I run
./prepare I get

mv Makefile.amt Makefile.am
automake: configure.in: required file `../config.guess' not found
automake: configure.in: required file `../config.sub' not found

Some part of the preparation process failed.

Is that a problem of my machine or a bug?

Thanks

The answer to your first question is to plot an
arbitrary function outside of the range of the plot;
i.e., splot -10 and then set zrange between 0 and 1 or
whatever.

The second question I'm not too sure about. In 2D
plots you can do the following:
set xzeroaxis lt -1
set yzeroaxis lt -1
unset border
set xtics axis
set ytics axis

This gives you what I think you want, but it only
works in 2D (I think) I don't know about 3D.

Hi,
I was looking at http://dynamicnetservices.com/~will/gnuplot/ 
<http://dynamicnetservices.com/%7Ewill/gnuplot/> which attempted to plot 
3D images using gnuplot. Im trying to plot 3D images too but they're 
more of objects rather than shapes. I was wondering how do you plot 
hemispheres or half hemispheres. What Im really attempting to plot is an 
image which looks something like 
http://www.resa.net/nasa/images/io/io%20core.JPG 
<http://www.resa.net/nasa/images/io/io%20core.JPG> using gnuplot.
Any ideas?
Thanks for your help.
Cheers
Astan

Thank you for your reply.

Can it be automatically done? Actually I generated the data file by
running some  clustering program on the raw data, so I don't know how
many clusters there are in the data file if I don't open and inspect it.
In the manual it says "Data separated by double blank records are
treated as if they were in separate data files" , so I think it should
be handled correctly. =20
Have anyone done this before?

Hi,
Try:

plot 'your_data_file' index 0 u 1:3 with points 1, '' index 1 u 1:3 w
points 2

and read more by typing 'help index' at gnuplot's prompt.

Good luck!
