Hi I have a file that I want to bin.
I am using this code:

Hi,
I am trying to make a plot of an ASCII file using GNUplot, but I keep getting error msg:

GNUPLOT(1) General Commands Manual GNUPLOT(1)
NAME
gnuplot - an interactive plotting program
SYNOPSIS
gnuplot [X11 options] [options] [file ...]
DESCRIPTION
Gnuplot is a command-driven interactive plotting program.
If file names are given on the command line, gnuplot loads each file with the load command, in the order specified, and exits after the
last file is processed. If no files are given, gnuplot prompts for interactive commands.
Here are some of its features:
Plots any number of functions, built up of C operators, C math library functions, and some things C doesn't have like **, sgn(), etc.
User-defined constants and functions.
All computations performed in the complex domain. Just the real part is plotted by default, but functions like imag() and abs() and arg()
are available to override this.
Many presentation styles for plotting user data from files, including surface-fitting, error bars, boxplots, histograms, heat maps, and
simple manipulation of image data. There is an on-line demo collection at
http://gnuplot.info/demo
Nonlinear least-squares fitting.
2D and 3D plots with mouse-controlled zoom and rotation.
Shell escapes and command line substitution.
Load and save capability.
Support for a huge variety of output devices and file formats.
OPTIONS
-p, --persist lets plot windows survive after main gnuplot program exits.
-e "command list" executes the requested commands before loading the next input file.
-h, --help print summary of usage
-V show current version
X11 OPTIONS
Gnuplot provides the x11 terminal type for use with X servers. This terminal type is set automatically at startup if the GNUTERM environ-
ment variable is set to x11, or if the -display command line option is used. For terminal type x11, gnuplot accepts the standard X Toolkit
options and resources such as geometry, font, and background. See the X(1) man page for a description of common options. For additional X
options specific to gnuplot, type help x11 on the gnuplot command line.
ENVIRONMENT
A number of shell environment variables are understood by gnuplot. None of these are required.
GNUTERM
The name of the terminal type to be used by default. This can be overridden by the gnuplotrc or .gnuplot start-up files and, of
course, by later explicit "set terminal" commands.
GNUHELP
The pathname of the HELP file (gnuplot.gih).
HOME The name of a directory to search for a .gnuplot file.
PAGER An output filter for help messages.
SHELL The program used for the "shell" command.
FIT_SCRIPT
Specifies a gnuplot command to be executed when a fit is interrupted---see "help fit".
FIT_LOG
The name of the logfile maintained by fit.
GNUPLOT_LIB
Additional search directories for data and command files. The variable may contain a single directory name, or a list of directories
separated by ':'. The contents of GNUPLOT_LIB are appended to the "loadpath" variable, but not saved with the "save" and "save set"
commands.
GDFONTPATH
Several gnuplot terminal drivers access TrueType fonts via the gd library. This variable gives the font search path for these driv-
ers.
GNUPLOT_DEFAULT_GDFONT
The default font for the terminal drivers that access TrueType fonts via the gd library.
GNUPLOT_FONTPATH
The font search path used by the postscript terminal. The format is the same as for GNUPLOT_LIB. The contents of GNUPLOT_FONTPATH
are appended to the "fontpath" variable, but not saved with the "save" and "save set" commands.
GNUPLOT_PS_DIR
Used by the postscript driver to locate external prologue files. Depending on the build process, gnuplot contains either a builtin
copy of those files or simply a default hardcoded path. Use this variable to test the postscript terminal with custom prologue
files. See "help postscript prologue".
FILES
gnuplotrc
When gnuplot is run, it first looks for a system-wide initialization file named gnuplotrc. The standard location of this file
expected by the program is reported by the "show loadpath" command.
.gnuplot
After loading the system-wide initialization file, if any, Gnuplot looks for a private initialization file in the HOME directory.
It may contain any legal gnuplot commands, but typically they are limited to setting the preferred terminal and line types and
defining frequently-used functions or variables.
fit.log
The default name of the logfile output by the "fit" command.
