NAME

muplot - plot a multi-curve figure from multiple data by using Gnuplot

SYNOPSIS

muplot [ OPTION ]... [ STYLE ] [ FILE ] [ AXES ] [ FILE ] [ AXES ] ...

DESCRIPTION

Muplot is a simple, non-interactive gnuplot-wrapper to plot a multi-curve figure from multiple data (files). It can produce PostScript, PDF, PNG or JPEG output file formats.

OPTIONS

--help |-H

display help

	-h		display short help
	-V		print program version number
	-s		create PostScript-file
	-S		send PostScript output to STDOUT (the same as ’-s -o -’)
	-n		create PNG-file
	-j		create JPEG-file
	-p		create PDF-file (requires the gnuplot "pdfcairo" driver)
	-X		don’t set the terminal to ’x11’ (use gnuplot’s default instead)
	-r0		reload data files continuously (default 8640:10)

-r <N:dt>

reload data files continuously by the specified config values

-c <cmd>

execute gnuplot command(s) (using the default plot style)

	-m		monochrome plot (valid for PostScript or PDF)
	-l		set plot size to 800x600 (valid for PNG and JPEG)
	-o		base name of the output file
	-q		quiet mode (all messages except errors to be suppressed)

-F <str>

input-data field separator (default is a single space character)

-i

ignore local command file ’./.muplotset’

-I <file>

specify an alternative command file instead of ’./.muplotset’

-U

do not sort the file list

-T <dir>

use this directory for temporary/working output files

Styles/Settings:

	lp		lines and points
	l		lines
	p		points
	pp		circle points
	nn		various points (types)
	d		dots
	b		boxes
	g		grid
	nk		do not plot keys (skip file names lables)
	e		errorbars - default used columns are 1:2:3 (x:y:yerror)
	a		fields with arrows; The data file has a special format in this case. Use ’prefield’ to prepare such data files.

dt=<fmt>

date/time series with the specified format; For example: dt="%H:%M.%S@%H:%M" where the first part, in front of "@", defines the data format, and the second part defines the format that will be used for tic labels. Here, hours and minutes are separated by ‘:’, respectively minutes and seconds by ‘.’ Another example is date and time stamp: dt="%Y-%m-%d %H:%M:%S"

plot 3-d data using 1:2:3

u=<fmt>

user specified plot style format (as defined in Gnuplot); For example: u="points pointtype 2 pointsize 3"; To see the present terminal and palette capabilities of gnuplot use the command ’muplot -c test’.

s=<opt>

user specified setting (as defined in Gnuplot); For example: s="logscale x"

Axes:

x:y,x:y-z

columns in the file defining the x/y-axes of the curve(s); Default are 1:2 or 1:2:3 for data with errors. In case that only one column is provided the default axes are 0:1 - the x-axis will be a simple index then.

File(s) could be a single file name whereas ’-’ means <stdin>, many files enclosed in ’’ or "" like "file1 file2 file3", or any valid shell pattern as for example "*.dat". The files ’$HOME/.muplotset’ and ’./.muplotset’, if existing, will be included at the beginning of the gnuplot script. The command block between "#BEGIN" and "#END" in those files will be pasted to the end of the script. If you want that the global ’$HOME/.muplotset’ is ignored, create in your local directory a file named ’.muplotset.noglobal’. In case you want to view the output, define the env variable MUPLOT_VIEWER and export it, for example:

MUPLOT_VIEWER="xpdf -z page"; export MUPLOT_VIEWER

Then the program will prompt you to view the plot, and after confirmation the viewer will present the graphics. If the postscript file format is chosen (’-s’ option), and MUPLOT_VIEWER is not defined, the viewer is preset to ’gv’, and per default you are prompted to view the output. To disable this behavior use the command "unset MUPLOT_VIEWER".

EXAMPLES

1) On X-terminal view a multi-curve plot of all data-files with extension ’dat’

muplot "*.dat"

2) Print a sinus curve in black-and-white color on a PostScript-printer

muplot -m -S -c "set title ’Function f(x)=sin(x)’; plot sin(x);" | lpr

3) Plot data from file "example.dat" using columns 1:2, 3:4, and 3:5 as x/y-axes in the multi-curve plot; a PostScript-file with the name "example.ps" is automatically created.

muplot -s example.dat 1:2,3:4-5

4) Create graphics in PDF-format reading data from file "example.1.dat" (columns 1:2), and from file "example.2.dat" (columns 3:4)

muplot -p lp example.1.dat 1:2 example.2.dat 3:4

5) View file where the first column is data, and the third and forth columns are date of the form ’yyyy-mm-dd’ and time in the form ’hh:mm:ss’

cat example_counts_per_second.dat | muplot dt="%Y-%m-%d %H:%M:%S" - 3:1

6) Plot 3-dimensional data from file "example_3d.dat" using the 1,3, and 5-th data columns with dots-plot-style, enabling grid, setting the xrange to [0:10], disabling keys and defining a plot-title

muplot nk g d 3d s="xrange [0:10]" s="title ’This is a 3-d plot’" example_3d.dat 1:3:5

7) Replot data 1000 times every 5 seconds and write temporary created files in the ’/tmp’ directory; This scenario is useful in case of growing or otherwise changing over time data-file

muplot -T /tmp -r 1000:5 example.dat
