kmplot 4:3.5.2-0ubuntu9 (powerpc binary) in ubuntu dapper

 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.
 .
 This package is part of the official KDE edutainment module.
