JFunctionViewer

JFunctionViewer is a versatile and straightforward OpenSource function plotter that offers an outstanding user experience. To start using JFunctionViewer, all you need to do is click the "Start" menu item on the left, and you're off to the races.

While the web-based version restricts saving or loading files to disk, this isn't so much of an issue since JFunctionViewer offers a host of other features to enhance your work. Here are some of the key features that make JFunctionViewer stand out from other plotter apps:

- Plotting of functions
- Save plotted functions as an image (please note that the applet cannot do this)
- Save and load functions in an XML-format to and from disk
- Plotting of functions with parameters, such as sin(a+x) or a*sqrt(x+shift)
- Trace functions, enabling users to see the y value for a given x value.

Overall, JFunctionViewer is an excellent tool for anyone who wants to create and plot functions with ease. The extensive list of features, along with its user-friendly interface, make JFunctionViewer a must-have for students, teachers, and anyone who needs quality graphing and plotting software.
