To create a graph, particularly a math graph, Function Grapher is a good choice. It's easy to use and powerful, can graph function and table data in 2D,2.5D and 3D.

Function Grapher Main Features:

---

Ability to graph functions in 2D and 3D. By extending the third dimension, you can create a graph of 2D function in 2.5D.

Ability to graph functions of 2D in Cartesion and polar coordinate system; ability to graph functions of 3D in Cartesion , cylindrical and spherical coordinate system.

Ability to create a graph of regular table data in 2D, 2.5D and 3D.

Ability to set and modify the color, material, model style and smoothness of 2.5D and 3d math graphs.

Ability to custome the appearance of axis and the parameters of light.

Ability to save graphs as pgp format or bmp format.

Ability to cut, copy, paste and delete graph(s).

Ability to move, zoom and rotate graphs.

Ability to plot graphs view from the front, right and top.
