KmPlot

Other languages:

KmPlot is a mathematical function plotter.

It is part of the KDE Education Project.

KmPlot has built in a powerful parser. High precision printouts with correct metric scale are very useful as worksheets in math and science lessons.

It can plot different functions simultaneously and combine their function terms to build new functions. It supports functions with parameters. You can change the parameters by moving a slider and see how the plot will change.

Features

powerful mathematical parser
precise metric printing
different plot types:
- Cartesian
- parametric
- polar
- implicit
- differential
highly configurable visual settings (plot line, axes, grid)
export to bitmap format (BMP and PNG) and scalable vector graphics (SVG)
save/load complete session in readable xml format
trace mode: cross hair following plot, coordinates shown in the status bar
support zooming
ability to draw the 1st and 2nd derivative and the integral of a plot function
support user defined constants and parameter values
various tools for plot functions:
- find minimum/maximum point
- get y-value and draw the area between the function and the y-axis

Example Plots

x(t)=0.5(t-2sin t) y(t)=2(1-2cos t)	rf(x)=x
x(t)=5sin(3t) y(t)=3cos(5t)	f(x)=3sin x g(x)=5cos(2x-pi/2) h(x)=f(x)+g(x)
