Tra le features principali del programma:

- Unlimited number of 2D and 3D graphs can be plotted in one coordinate system using different colors and lighting conditions.
- Functions can be parametric, and can include a time variable - this feature allows creation of animated graphs and models.
- Support for three systems of coordinates: Cartesian, cylindrical and spherical.
- Graphs can be plotted using points, lines, and surfaces. In the last case you can also use a light source to create realistic surfaces.
- Many coordinate system appearance options (parameters of axes, grid, background, etc.).
- Ability to import and export data in several popular file formats (comma, tab, or space separated values).
- Ability to copy the plotted graphs and paste them into your own documents as a picture.
- Built-in expression calculator.
- Fully customizable user-friendly interface with support for MS Office 2000 ® and MS Office XP ® styles.
- Support for majority of the modern OpenGL video accelerators.
