You can specify an unlimited number of graphs which can be plotted using different colors and lighting conditions. It is possible to plot functions with 1 to 3 independent variables including a time variable for animation. 3D Grapher supports Cartesian, polar, cylindrical or spherical coordinates. You can rotate, move and scale the graphs using mouse or keyboard. The presentation-quality graphs can also be copied and pasted into your own documents.
