Function Graph Properties

This window appears when you want to add a new graph of a function (by clicking or Graphs | Add Function Graph) or edit the existing one (by clicking or Graphs | Edit Graph).

Name - a short description of the graph. It is shown in the Workspace window and in the Graph Info window.

Coordinates - functions can be plotted in any of the three coordinate systems: Cartesian (X, Y, Z), cylindrical (a, R, Z), or spherical (a, b, R). For more information see the Coordinate Systems section of this manual.

Function - function to be plotted. Use u, v, and t as independent variables. For more information on functions and syntax see the Expressions section.

Min U, Max U, Min V, Max V - define the domain of the independent variables (u and v). The domain of the t variable is the same for all graphs and can be defined in the Plot Options dialog.

Steps - determines the accuracy of the plotting. The more is the number of steps, the better is the accuracy. Sometimes it's useful to define a smaller number of steps, e.g. when you plot the graph with points. Number of points of the graph is equal to the number of steps plus 1.

Each graph has its own appearance parameters that can be specified in the Graph Appearance area.
