Z-Plot is a free software program that allows you to visualize a multitude of mathematical functions and curves. The software has a powerful mathematical formula interpreter, that also allows the user to handle complex numbers easily. The display can be switched from 2D to 3D mode. Additionally, diagrams can be made from data tables.

Features:

* 3D/2D display that be rotated and scaled freely
* The common mathematical functions are supported
* Calculating with complex numbers is supported by any mathematical operation. Additionally, it is possible to determine the real part, imaginary part, argument and absolute value of complex expressions.
* Chose between linear and logarithmic axes scaling.
* Integrated calculator including numerical integral and differential calculus
* Make diagrams from a spreadsheet
* With detailed online help.
