What was the x range?  What version of gnuplot ("show version long" 
output would be nice) is this?

> I can't believe this is not defined ! 

It very well might be.  Let me show you why:

gnuplot> print gamma(101)
9.33262154439422e+157
gnuplot> print gamma(101)**2

gnuplot> print gamma(101)**2
                ^
          undefined value

gamma is a *rapidly* growing function, and your computer has a finite 
range of values it can represent.

[Gnuplot-info] All points y value undefined...

[Julien D. <Jul...@da...>]

Hi everyone,
I am trying to plot the gamma function, and have this error message....

gnuplot> plot 0.6*gamma(101)*gamma(100.6-x)/ 
(gamma(100+0.6+1)*gamma(100-x+1))
                                                                              ^
          all points y value undefined!


I can't believe this is not defined ! I don't understand the error  
message. help???

[Gnuplot-info] How to pronounce gnuplot?

[Banlu K. <ob...@gm...>]

Dear list,

How do I pronounce gnuplot?

Thanks!

Re: [Gnuplot-info] special plot need -- splot matrix from not-that-regularly organized data file

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

if you would do a normal 'splot', selection of data section using 'every'
would work, but with 'matrix' gnuplot tries to figure out what the
dimensions
of the matrix are, and there it fails due to those non-data lines (e.g. 'k =
1').

Re: [Gnuplot-info] binary pipes in windows

Please use console mode of gnuplot (gnuplot.exe but not pgnuplot.exe+wgnuplot.exe) on CVS release
(4.3) for binary data via pipe.

The CVS  binary for windows available at

I got exactly the opposite on vista 32bit, mono is ok, color is empty. 

On linux, both are correct.

[Gnuplot-info] binary pipes in windows

[franco b. <fra...@gm...>]

I'd like to generate plots on the fly, from c and fortran programs. 
Up to now, in linux, I have found no problem at all. 
In windows using cygwin, everything ok. 
When using pgnuplot, I discovered that binary pipes are not properly
handled. The following program produces a weird plot
when used as a pipe, while I can write data to a file and plot them without
problems. 

Notice that I tried to open the pipe in "binary" (is the distinction between
binary and text files still present in wondows?) but the result is the same.
I'm wondering whether pgnuplot correctly handles binary data... 

#include <stdio.h>
#define N 100
main(){
  int i;
  float x[N];
  FILE *gp;

  for(i=0; i<N; i++) {
    x[i] = (float) i/N;
    x[i] = x[i]*x[i];
  }
  gp = popen("pgnuplot", "w");
//  gp = fopen("datafile.dat", "wb");
  fprintf(gp, "plot '-' binary array=%d format='%%float' w l\n", N);
  fwrite(x, sizeof(float), N, gp);
  fflush(gp);
  getchar();
  fclose(gp);
}

Re: [Gnuplot-info] special plot need -- splot matrix from not-that-regularly organized data file

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

Thanks all for your great help, the modification into comments is trivial
and I will do that!

So actually the problem boils down to how gnuplot see a data file. In my
naive imagination, it recognizes line separators(if there exists this in
linux), and thus it could count how many lines it is instructed to read in
and how the readin data should be organized and displayed. Following this
logic, it seems to me not a big problem to splot continuously the data file
I presented. But it does not work out as I expected, can anybody clarify
this for me?

Re: [Gnuplot-info] special plot need -- splot matrix from not-that-regularly organized data file

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

turn all non-data lines into comments by adding a '#' in front
and plot with

splot 'file' matrix ind 0 w l, '' matrix ind 1 w l, ...


otherwise, you need gnuplot 4.3-cvs.
the first plot goes into a table:

set table
set out 'table'
splot 'file' every 2:1:1:1:3:1, '' every 2:1:5:1:8:1, ...
set out

see 'help every', the 1st block ('d channel') in your
data file is empty, the 2nd contains the data from 'k=1'
to 'k=whatever', the 3rd ('m channel') is empty, the
4th contains data, that's why we take every 2nd
block.
inside one block data lines are selected from 1 to 3,
5 to 8, a.s.o.

and this table is then read in again:

set xrange [0:2]
splot 'table' matrix ind 0, '' matrix ind 1, ...

the warnings are due to the 'i' at the end of each data line
in 'table'.

Re: [Gnuplot-info] 3D plot with gnuplot?

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

just an idea how it could be done:

set parametric
set xyplane at 0.0
set xrange [-10:10]
set yrange [-10:10]
set urange [-8:8]
set vrange [-8:8]
splot u,v,sin(sqrt(u**2+v**2))/sqrt(u**2+v**2), \
u,10,sin(sqrt(u**2+0**2))/sqrt(u**2+0**2), \
-10,v,sin(sqrt(0**2+v**2))/sqrt(0**2+v**2)

[Gnuplot-info] special plot need -- splot matrix from not-that-regularly organized data file

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

I have a data file organized as the following

d channel ...

k = 1
0.34  0.89   0.99
0.23  0.67  0.02
0.65  0.99  0.45
k=2
0.45  0.78  0.99
0.23  0.78  0.86
0.12  0.43  0.23
...

m channel ...

k=1
...

I need to skip the first 3 lines then splot the first set of data forming 3
by 3 matrix, and then skip a line, splot the second set of data forming 3 by
3 matrix again ... How can I do that?

If I use splot 'file' ev 4:6 matrix , then it complains that
Matrix does not represent a grid,

Can anybody explain where the above command goes wrong?

Thank you very much!!

Re: [Gnuplot-info] special plot need -- continuously plot 2D graphs from one data file

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

either with gnuplot 'animate' option for the 'gif' terminal

http://www.gnuplot.info/docs/node378.html

or - if your gd library doesn't support this - externally
with e.g. 'gifsicle':

set term gif
set out "| gifsicle -m -o out.gif -d 100 --multifile -"
# do all the plot commands
plot ...
plot ...
# at the end close the sequence
set out

Re: [Gnuplot-info] special plot need -- continuously plot 2D graphs from one data file

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

Thanks so much! this is very promising and I will definite have a try.

By the way, how about generating the sequence of plots into .gif file, or
animated file

Re: [Gnuplot-info] special plot need -- continuously plot 2D graphs from one data file

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

you could use the 'reread' command:

[Gnuplot-info] special plot need -- continuously plot 2D graphs from one data file

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

I have a data file with thousands of blocks of data, I can use plot 'file' u
2:3 index 1:1 to plot say the 1st block of data, I need to continuously plot
the 2nd, 3rd .... of data on the same figure, cleaning the previous one when
drawing the present one, till it reaches the end of the file. Between two
plots, there should be an adjustable delay so as to give some visual effect.
This is very helpful for me to track the evolution of the process.
Meanwhile, if this animation could be saved as say .gif file, it would be
great! I don't know whether it is possible to realize in gnuplot. Thanks for
sharing your advices ..

Re: [Gnuplot-info] Draw vertical line at a specified date

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

you could use the specific dates to generate an alternating function
which switches between two values which are outside your y-range.
an example:

set xdata time
set timefmt "%d.%m.%Y %H:%M"
set yrange [0:7]
set clip two
plot '-' us 1:3 w lp, '-' us 1:(3.5+4.0*(-1)**($0+1)) w steps
01.01.2009 15:30 1
02.01.2009 16:30 2
03.01.2009 17:30 3
04.01.2009 18:30 4
05.01.2009 19:30 5
06.01.2009 20:30 6
e
01.01.2009 23:00
01.01.2009 23:00
03.01.2009 23:00
05.01.2009 23:00
05.01.2009 23:00
e

Re: [Gnuplot-info] tics without name

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

set xtics format " "
or
set ytics format " "
depending on how you arrange your plots.
it may be necessary to adjust some margins.

[Gnuplot-info] tics without name

Hi,
I plotted a multigraph. I want to keep the tics but remove the tics label
(numbers)
Is there a way to do it?
Thanks

[Gnuplot-info] plot matrix as many graphs with different colors

[Torquil M. S. <to...@gm...>]

Hi!

I'm am plotting many graphs in one plot, by using

plot 'data.txt' matrix using ($1/M):($3) notitle with lines

where M is the number of data points in one of the directions (but that 
is not important here). The M is necessary to normalize the axis scale 
in the x-direction.

I get one graph in the plot for each line in the data file. The data 
file is simply of the form

N N N N N N
N N N N N N
N N N N N N
.
.

But I would like each graph to have a different colour. Does anyone know 
how to do this? The best thing would be if the colours are chosen 
automatically.

Best regards
Torquil Sørensen
