JFunctionViewer

JFunctionViewer is a Java-based application designed to help users plot mathematical functions of limited complexity. It requires no installation and can run on any system that has Java installed.

One of the advantages of using this application is that it requires no installation, though you need to make sure Java Runtime Environment is installed on your PC. You can launch it from any location, and it will leave no traces behind.

Since it is a Java-based utility, it can be run on multiple platforms, which is a big plus if you often switch between computers running different operating systems.

Once you launch the application, everything should be more or less self-explanatory. You will see two windows, one for entering functions and one for viewing the generated graphs.

You can insert multiple mathematical functions and assign a specific color to each one so as to make them easier to tell apart. It is possible to hide any of them from the graph at any time.

The graph window can be resized freely, and users can also change the background, grid and axis color. Last but not least, you can define the plotting area.

When you’ve added all your functions and fine-tuned everything, you can just access the File menu to save your work. You can either export it to a JFV XML file, which can be edited later, or a PNG image file.

JFunctionViewer is a good choice for users who are looking for a relatively simple application that can help them plot mathematical functions. It is lightweight and does not require installation, while also providing users with a quick guide that can help them understand its features.
