Function Grapher is an easy-to-use software for 2D, 2.5D and 3D function graphing, animation and table data visualization. 2D and 2.5D function graphs can be plotted in Cartesian and polar coordinate systems,and 3D function graphs can be plotted in Cartesian,cylindrical and spherical coordinate systems.

functions, and looping. However the real power is in the ability to add custom functions through method calls. When a custom function is encountered in a script an event is triggered, telling you which function was used and makes the parameters to the function available for retrieval and handling in your code. When you set the return value of your function, script execution resumes. There are events that allow a trace debugger to be built, variables
