TrafficObjects 1.0.7 (Default branch)
04-07-2008
TrafficObjects periodically fetches data from remote databases and files and enables users to graphically create realtime streaming charts for monitoring and data mining. Plot data is fetched from databases such as Oracle, PostgreSQL, Microsoft SQL Server, Sybase, MySQL, etc. Data can also be fetched from text files such as CSV, Tabular, and PostgreSQL Log files.

MUPLOT(1) User Commands MUPLOT(1) 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 --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
