[Gnuplot-info] Question

[Nicolas B. <ng...@mi...>]

Hi! First, I'd like to congratulate gnuplot developers for such a
versatile program! It's amazingly simple andd useful!

My question (that I couldn't find in the FAQ) is: "How do I store the
output of a "fit" in a  file?, i.e. the fitting parameters, chi2, etc.?

Thanks, Nicolas Busca.

[Tia G. <ti...@ho...>]

Hey,
I am working on using gnuplot in a source code I am modifying. However, in 
your documentation I couldn't find anything, which said how to pass an array 
of pointers into gnuplot. For example: I want to pass int *hist[..]; into 
gnuplot so as to plot a graph using the address of each cell (0,1,2,3....) 
as the x-axis and the value contained in each as the y-axis. Should I stream 
the array into a text/binary file and then use the program?
I would appreciate your help,
Thanks
-Tia.

[Gnuplot-info] Question

[Brian S. <gr...@st...>]

Hello: 

 

I have a datafile that I wish to plot.  When I write the syntax, I get a
message that the file is as follows: 

 

Util C:  No such file or directory. 

 

I placed the file in the same directory as GNU Plot.  Also the original file
is a txt file but rename it as a .dat file. 

 

Thanks Brian

seems like you are doing on ms-windows.
the data file should be in your current directory, i think, 
not the same directory as gnuplot binary.
or, try telling the full path name of the data file, like

gnuplot> plot "c:\the\directory\file.dat" us 1:2

anyway you need to tell your OS and the exact situation and
command you wrote to get the error.

Hi,

I have about a million points in excel that I'm trying to plot.

How would I go about doing this?

What would make a file "removable"?

Dear Nicolas,
running gnuplot, help fit is your friend ;-). I could even have said RTFM.=

gnuplot >
gnuplot > help fit

Examples:
       f(x) =3D a*x**2 + b*x + c
       g(x,y) =3D a*x**2 + b*y**2 + c*x*y
       FIT_LIMIT =3D 1e-6
       fit f(x) 'measured.dat' via 'start.par'
       fit f(x) 'measured.dat' using 3:($7-5) via 'start.par'
       fit f(x) './data/trash.dat' using 1:2:3 via a, b, c
       fit g(x,y) 'surface.dat' using 1:2:3:(1) via a, b, c

 After each iteration step, detailed information about the current state
 of the fit is written to the display.  The same information about the
 initial and final states is written to a log file, "fit.log".  This file
 is always appended to, so as to not lose any previous fit history;  it
 should be deleted or renamed as desired. By using the command=20
 `set fit logfile`, the name of the log file can be changed.

info gnuplot in a shell environment may also help.
Take care
