FuncPlotter is a Java Swing application that can display two-dimensional plots of explicit functions in one variable (ie, functions of the form y = f(x), where f(x) is an arbitrary function composed from a set of common mathematical operations).

There have been no major improvements to the application since it was first released in 2006. If you're looking for an open-source application for plotting functions, you're likely to find a better application elsewhere.

Features

• Up to 20 functions can be plotted simultaneously. The colour of each plot can be specified.
• FuncPlotter can save a set of up to 20 functions to a file and can load files saved in this way. The files are saved either as XML or in a simple text format, allowing you to create and to edit files with a text editor.
• Multiple documents (sets of functions) can be open simultaneously in a tabbed window.
• Changes that are made to a document can be undone and redone.
• When the mouse cursor is over the plot area, the x and y coordinates at the cursor are displayed.
• Plots can be scrolled by clicking on buttons, rotating the mouse wheel, dragging the mouse or pressing keys.
• You can repeatedly scale a plot (zoom in and out) by a factor that can be independently selected for each of the x and y dimensions.
• Plots can be exported as an image file in PNG format.
