[Gnuplot-info] gnuplot

[Dmitrij J. <dmi...@gm...>]

Hello.
My name is Dmitry Jaworski, I am a student of physics at Warsaw
University. I am currently engaged in processing of experimental data
for my master's work.
The data-processing program I use is gnuplot. I would like to ask you
if it is possible, when fitting, to establish certain relationships
between parameters. For example: for the fitting, I use a function f
(x) = a + b * x and parameter 'a' must be > -3b (larger than -3b).
I'll be very grateful for the help.
Sincerely.
D J

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

then you are using an older version of gnuplot.

see
   help set terminal png
for the allowed options.

Re: [Gnuplot-info] Why I am having this error?

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

yes,
either for the whole plot

set terminal png fontscale 0.8

or for the x-tics

set xtics font ",10"

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

do you use both?

set xtics 2*60
set format x "%H:%M"

Re: [Gnuplot-info] summorizing data per day not working

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

'smooth frequency' makes the data monotonic, but x-values which are not
in the data file are not taken into account.
how should gnuplot know which x-intervals you prefer?

just add a dataline for each date you want to show up in the plot
with a y-value of 0 into the datafile.

[Gnuplot-info] 2-D color scatterplot using gnuplot v 4.0 patch 0

[Edward N. <edw...@gm...>]

I have a datafile with three columns:

x-value    y-value    color

where color is an integer representing a simple color (i.e. black, green,
red, etc.). I've looked through the documentation, looked at demos, forums,
and tried many variations of pm3d, splot, and plot with lt, but have been
unsuccessful. If anyone has any idea how to do this so that all the data can
remain in one file, your help would be greatly appreciated. Thanks in
advance.

It isn't quite clear what you want but you might be looking for the

And where in the documentation did it make you think that was the way to 
plot a datafile with gnuplot?

You're supposed to use that file as the argument to a 'plot' or 'splot' 
command.  You'll really have to start with the documentation before you 
jump off the deep end like that.

Hello Thomas

Many many thanks for this.  I will try to test your
patch this weekend and report back.

That's it, John. Thanks! Both of the pdfcairo and epslatex terminals produce good results from the Gnuplot terminal when I terminate the instructions with "set output".

Re: [Gnuplot-info] name of current script

the best place to set such a variable would be the
'load_file()' routine in 'misc.c'.

two lines need to be added there:

[Gnuplot-info] Gnuplot 2d density colours

[snapple2 <sna...@ho...>]

Hi, I new to gnuplot and have managed to plot my 2d data set on a scatter
graph but as there is so much data that the density relationship between the
two variables is lost into one big blob of colour....is there anyway of
creating a density colour ramp in order to show the density of plots within
my data? i;ve looked all over the internet and not had much luck. if anyone
is familar with ENVI i want to try and achieve the same affect as the 2d
density slice on that?..any help would be really appreciated

thanks

[Gnuplot-info] Problem with the gnuplot terminal

[Vic N. <vi...@no...>]

I am having a problem with the gnuplot terminal in Gnuplot 4.4.2.
I wonder if anyone has an idea why.

Here is the problem. First I apply gnuplot to a simple script file from
bash:
  $ gnuplot test_pdfcairo.np
The result is a good "test_pdfcairo.pdf".
The script file "test_pdfcairo.np" reads
  #!/usr/local/bin/gnuplot
  set term pdfcairo
  set output "test_pdfcairo.pdf"
  test

So far so good. Now I open the gnuplot terminal and execute the same
instructions from the terminal:
  $ gnuplot
      G N U P L O T
      Version 4.4 patchlevel 2
      ...
  gnuplot> set term pdfcairo
    Terminal type set to 'pdfcairo'
    Options are ' size 5.00in, 3.00in '
  gnuplot> set output "test_pdfcairo.pdf"
    an empty "test_pdfcairo.pdf" is created
  gnuplot> test
    supposedly "test_pdfcairo.pdf" is filled with the "test" pattern
Unfortunately the new "test_pdfcairo.pdf" is no good. When I try to
open it with Adobe Reader I get the message
  There was an error opening this document.
  The file is damaged and could not be repaired.

Apparently there is nothing wrong with the pdfcairo terminal in
Gnuplot, but I cannot use the pdfcairo terminal from the
Gnuplot terminal.

I have the same problem with the epslatex terminal in Gnuplot.
When I run
  gnuplot> set term epslatex color colortext
  gnuplot> set output "test_epslatex_output.tex"
  gnuplot> test
the resulting "test_epslatex_output.tex" has no chance of working.
The crucial closing lines
      \gplbacktext
      \put(0,0){\includegraphics{test_epslatex_output}}%
      \gplfronttext
    \end{picture}%
  \endgroup
are missing. The "test_epslatex_output.tex" file is bad as well.
Many lines are missing at the end, and the image is incomplete.

Executing the same instructions from bash
  $ gnuplot test_epslatex.np
produces valid "test_epslatex_output.tex" and
"test_epslatex_output.eps" files. And the line
  input "test_epslatex_output"
in an appropriate LaTeX script produces the desired test picture.

Any ideas as to the cause of this problem would be greatly appreciated.

Whether or not you can plot dashed lines depends on the terminal.
 
For example I often use the epslatex terminal. The Gnuplot commands
   set term epslatex color colortext
   set output "test_epslatex_output.tex"
followed by "\input{test_epsoutput}" from in an appropriate LaTeX script produces a PDF of the epslatex test picture. Most of the lines in this picture are dashed or dotted. For example the lines 0 through 9 are all different and 9 of these are dashed and/or dotted. Here is the test picture.

On the other hand the commands set term pdfcairo set output "test_pdfcairo.pdf" produces a PDF file with only line type 0 dotted. There are no dashed lines possible. Here is the test picture.
 		 	   		  

Re: [Gnuplot-info] how to ignore missing lines ? (not sure of proper title for this)

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

"$0" is the line number and has nothing to do with the data,
the matching (or missing) entries are in "$1".

on a unix-like system combine the 3 files:

join -t ',' -a 1 C.csv A.csv | join -t ',' -a 1 - B.csv > X.csv

(on a windows system install the 'coreutils' to use the 'join' command)

and then plot using the new file:

plot "X.csv" using 0:2:xticlabels(1) with linespoints title "C", \
"" using 0:4 with linespoints title "A", \
"" using 0:6 with linespoints title "B"

or without connections across gaps:

plot "X.csv" using 0:2:xticlabels(1) with linespoints title "C", \
"" using 0:($4) with linespoints title "A", \
"" using 0:($6) with linespoints title "B"

[Gnuplot-info] name of current script

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

Hello all

It would be rather useful if the current filename was
available from within a gnuplot script.

This suggestion was raised in 2008 and 2009
respectively:

  http://groups.google.com/group/comp.graphics.apps.gnuplot/browse_thread/thread/2b34fa67a0365173/8f8c63c891f59aeb?lnk=gst&q=%22current+filename%22#8f8c63c891f59aeb
  http://groups.google.com/group/comp.graphics.apps.gnuplot/browse_thread/thread/781545ccfbaada56/ebffa12161a37fe3?lnk=gst&q=%22get+filename%22#ebffa12161a37fe3

And, AFAIK, has not been resolved.

One approach might be:

assume the file 'myfile.gp' contains the lines:

    myfile = GPVAL_LOAD_FILE
    print "myfile = ", myfile

then entering the command:

    load "myfile.gp"

would display either of the following -- the first
being a simple echo and the second being the canonical
file path:

    myfile = myfile.gp
    myfile = /path/to/myfile.gp

On termination, GPVAL_LOAD_FILE would be unset.

Another approach (probably too late) would have been
to have the 'call' command assign the filename to $0
in line with most other shell positional variable
conventions.

If there is a work-around, that would be good to know.

best wishes
Robbie

Re: [Gnuplot-info] how to break key and plotting

i had a look at the newest gnuplot version, 4.4.3,
"announce.4.4.3" says:

* NEW set key maxcolumns N maxrows M

so these command options are now the official version.
