FuncPlotter is a combined Java application and applet for displaying two-dimensional plots of explicit functions in one variable.

FuncPlotter can display functions of the form y = f(x), where f(x) is an arbitrary function composed from a set of common mathematical operators.
Here are some key features of "FuncPlotter":

· It can be used either as a Java application or as a Java applet that is included in a page of HTML or XHTML.
· Up to 20 functions can be plotted simultaneously. The colour of each plot can be specified.
· When used as an application, 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 edit files with a text editor. (The ability to load and save files is not available in applet mode.)
· In application mode, up to 9 documents (sets of functions) can be open at once, each in its own window. You can switch quickly and easily between documents. However, the document windows are of fixed size and are overlayed: you cannot tile or cascade the windows. (Multiple windows are not available in applet mode, which uses only a single window.)
· 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.
· Plots can be zoomed in and out. Each of the x and y dimensions has its own independently selectable zoom factor.
· Plots can be exported as an image file in PNG format


Requirements:

· Java Runtime Environment

What's New in This Release: [ read full changelog ]

· The surrogate minus character (if there is one) is now used in the pop-up window that is displayed if an expression is too wide for the function list.
Other changes:
· In application mode, the configPath configuration property (ie, the system property specified by -Dapp.configPath) now accepts a list of directories separated by the system-dependent path separator instead of a single directory
