PYXPLOT(1) General Commands Manual PYXPLOT(1) NAME
pyxplot - a commandline data processing, graph plotting, and vector graphics suite. SYNOPSIS
pyxplot [file ...] DESCRIPTION
PyXPlot is a multi-purpose command-line tool for performing simple data processing and for producing graphs and vector graphics. The cen- tral philosophy of PyXPlot's interface is that common tasks -- for example, plotting labelled graphs of data -- should be accessible via short, simple and intuitive commands which require minimal typing to produce a first draft result. At the same time, these commands also take a sufficient range of optional arguments and settings to allow these figures to be subsequently fine-tuned into a wide range of dif- ferent styles, appropriate for inclusion in reports, talks or academic journals. As well as being a graph-plotting package, PyXPlot also has facilities for fitting mathematical functions to data, for numerically solving simple systems of equations, and for converting datafiles between different formats. Its mathematical environment can interpolate datasets, integrate and differentiate them, and take Fourier transforms. PyXPlot's ability to keep track of the physical units in which data are expressed, and to convert data between different units of measurement, mean that it can be used as a powerful desktop calculator. PyXPlot's interface bears some striking similarities to that of Gnuplot. Specifically, the commands used for plotting simple graphs in the two programs are virtually identical, though the syntax used for more advanced plotting often differs and PyXPlot's mathematical environ- ment is hugely extended over that of Gnuplot. This means that Gnuplot users will have a head start with PyXPlot: simple Gnuplot scripts will often run in PyXPlot with minimal modification. A number of examples of the graphical output which PyXPlot can produce may be found on the PyXPlot website: <http://www.pyxplot.org.uk/>.

kst -- plots scientific data SYNOPSIS
kst kst [ -F DATASOURCE ] [ -f STARTFRAME ] [ -n NUMFRAMES ] [ -s FRAMESPERSAMPLE [ -a ] ] kstfile kst datasource [ -f STARTFRAME ] [ -n NUMFRAMES ] [ -s FRAMESPERSAMPLE [ -a ] ] [ -P PLOTNAME ] [ -A] [ -d ] [ -l ] [ -b ] [ -x FIELD ] [ -e FIELD ] [ -r RATE ] [ -y FIELD ] [ -p FIELD ] [ -h FIELD ] [ -z FIELD ] [ --png filename ] [ --print filename [ --landscape | --portrait ] [ --Letter | --A4 ] ] DESCRIPTION
kst is a graphical data plotting tool, which includes the ability to plot live data (contiuously update the plot as new data becomes avail- able). kst may be run entirely from within its GUI, in which case no command line arguments are needed. kst has a powerful wizard for easily set- ting up new plots. In the second invocation, kst loads pre-saved plot specifications from the file kstfile and optionally may override some of the settings in that file. In the third invocation, kst displays plots of the data as directed in the default manner. Additional datasources may be specified on the command line with options for that datasource following it. Command line options generally apply to all subsequent options unless later overridden. OPTIONS
-A plot all curves in separate plots -a average frames (simple mean) when plotting with -s. --A4 use A4 sized paper for printing. Requires --print. -b plot as bargraphs. -d use points when plotting curves. -e FIELD use FIELD as the magnitude of error bars applied to the next plot. -F datasource override the datasource indicated in the kstfile and instead use datasource. -f STARTFRAME begin plotting at STARTFRAME frames into the data. Set to -1 to start at NUMFRAMES from the end of the data. -h FIELD plot FIELD as a histogram. -l use lines when plotting curves. --landscape use landscape orientation for printing. Requires --print. --Letter use US Letter sized paper for printing. Requires --print. -n NUMFRAMES plot at most NUMFRAMES frames of data. Set to -1 to indicate all of the data. -P PLOTNAME plot all plots in the plot named PLOTNAME. -p FIELD plot FIELD as a power spectrum plot. --png filename render to a portable network graphics (png) image with file name filename and quit. --portrait use portrait orientation for printing. Requires --print. --print filename print the plot to file filename and quit. -s FRAMESPERSAMPLE plot every FRAMESPERSAMPLE frames when plotting. -x FIELD use FIELD as the X-axis vector. -y FIELD plot FIELD as an XY plot. -z FIELD plot FIELD as an image. EXAMPLES
Plot all data in column 2 from data.dat. kst data.dat -y 2 Same as above, except only read 20 lines, starting at line 10. kst data.dat -f 10 -n 20 -y 2 also read col 1. One plot per curve. kst data.dat -f 10 -n 20 -y 1 -y 2 Read col 1 from data2.dat and col 1 from data.dat kst data.dat -f 10 -n 20 -y 2 data2.dat -y 1 Same as above, except read 40 lines starting at 30 in data2.dat kst data.dat -f 10 -n 20 -y 2 data2.dat -f 30 -n 40 -y 1 Specify the X vector and error bars: Plot x = col 1 and Y = col 2 and error flags = col 3 from data.dat kst data.dat -x 1 -e 3 -y 2 Get the X vector from data1.dat, and the Y vector from data2.dat. kst data1.dat -x 1 data2.dat -y 1 Placement: Plot column 2 and column 3 in plot P1 and column 4 in plot P2 kst data.dat -P P1 -y 2 -y 3 -P P2 -y 4 BUGS
Please report bugs to either the kst mailing list at kst@kde.org or to the kde bugzilla under the kst product at http://bugs.kde.org/. If you can run kst, you can easily report bugs by selecting Bug Report Wizard from the Help menu. AUTHOR
