KmPlot
KmPlot is a mathematical function plotter for the KDE Desktop. It has a powerful built-in parser. The graphs can be colorized and the view is scalable, so that you are able to zoom to the level you need. Users can plot different functions simultaneously and combine them to build new functions. It 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
- Plotting derivatives and integral functions.
