KMPLOT(1) KDE User's Manual KMPLOT(1)
NAME
kmplot - mathematical function plotter
SYNOPSIS
kmplot [-f, --function argument] [file] [KDE Generic Options] [Qt(TM) Generic Options]
DESCRIPTION
KmPlot is a mathematical function plotter for KDE. It has a powerful built-in parser. You can plot different functions simultaneously and
combine them to build new functions.
KmPlot supports parametric functions and functions in polar coordinates. Several grid modes are supported. Plots may be printed with high
precision in the correct scale.
KmPlot also provides some numerical and visual features, like filling and calculating the area between the plot and the first axis, finding
maximum and minimum values, changing function parameters dynamically and plotting derivatives and integral functions.
KmPlot is part of the KDE edutainment module.
OPTIONS
-f, --function argument
Initial function to plot
file
File to open
SEE ALSO
More detailed user documentation is available from help:/kmplot (either enter this URL into Konqueror, or run khelpcenter help:/kmplot).
There is also further information available at the KDE edutainment website[1].
