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 --version output version and license message -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) -c <cmd> execute gnuplot command(s) (the default plot style is used) -m monochrome plot (valid only for PostScript) -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) -i ignore local command file './.muplotset' -I <file> specify an alternative command file instead of './.muplotset' Styles: l lines p points lp lines and points (default) pp circle points d dots b boxes g grid 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 could be a date: dt="%Y-%m-%d". u=<fmt> user specified format as defined in Gnuplot 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 col- umn 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 '$HOME/.muplotset' and './.muplotset', if existing, will be included at the beginning of the gnu- plot script. The command block between "#BEGIN" and "#END" in those files will be pasted to the end of the script. If you want that the global '$HOME/.muplotset' is ignored, create in your local directory a file named '.muplotset.noglobal'. In case you want to view the out- put, 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 for- mat 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, set MUPLOT_VIEWER="". EXAMPLES
1) On X-terminal view a multi-curve plot of data files with extension 'dat' muplot l "*.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 lp 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 data where the third column is a date of the form 'yyyy-mm-dd' cat example_counts_per_day.dat | muplot dt="%Y-%m-%d" - 3:1 REPORTING BUGS
