2.5D Function Graph

Main Steps Of Creating 2.5D Function Graphs

To create a 2.5D function graph, following these steps:

1. If graphs created before are 2D or 3D, select File->New->2.5D Graph from the menus, or click button in Standard toolbar.
2. If current coordinate system is 2.5D Cartesian, select Draw->2.5D Function Graph->Cartesian from the menus, or click button in Plot toolbar; If current coordinate system is polar, select Draw->2.5D Function Graph->Polar from the menus, or click button in Plot toolbar.
3. Set some necessary options in 2.5D Function Graph Properties dialogbox, and click OK button.

Examples:
Some 2.5D examples are provided. You can find them in a directory in your setup path, setuppath\samples\2.5D.

Cartesian Graphs

To create a function graph in 2.5D Cartesian coordinate system, following these steps:

1. If graphs created before are 2D or 3D, select File->New->2.5D Graph from the menus, or click button in Standard toolbar.
2. Select Draw->2.5D Function Graph->Cartesian from the menus, or click button in Plot toolbar to open 2.5D Function Graph Properties dialogbox.
3. Enter function name in Name field; select an item in Form drop-down listbox according to the form of your function; the default option of Coordinate drop-down listbox is Cartesian, don't change it.
4. Enter the expression of your function and the values of variables in other fields.
   Note: Steps VarName(VarName indicates a variable name such as x, u) in 2.5D Function Graph Properties dialogbox shows the number of intervals between the minimum value and the maximum value of a variable. A larger value will result in a smoother curve.
5. Click OK button.

Examples:
Some 2.5D examples are provided. You can find them in a directory in your setup path, setuppath\samples\2.5D.

Polar Graphs

To create a function graph in 2.5D polar coordinate system, following these steps:

1. If graphs created before are 2D or 3D, select File->New->2.5D Graph from the menus, or click button in Standard toolbar.
2. Select Draw->2.5D Function Graph->Polar from the menus, or click button in Plot toolbar to open 2.5D Function Graph Properties dialogbox.
3. Enter function name in Name field; select an item in Form drop-down listbox according to the form of your function; the default option of Coordinate drop-down listbox is Polar, don't change it.
4. Enter the expression of your function and the values of variables in other fields.
   Note: Steps VarName(VarName indicates a variable name such as x, u) in 2.5D Function Graph Properties dialogbox shows the number of intervals between the minimum value and the maximum value of a variable. A larger value will result in a smoother curve.
5. Click OK button.

Examples:
Some 2.5D examples are provided. You can find them in a directory in your setup path, setuppath\samples\2.5D.

Graphing Explicit Function

To create a graph of explicit function, you should select item one in Form drop-down listbox in 2.5D Function Graph Properties dialogbox.

Examples:
Some 2.5D examples are provided. You can find them in a directory in your setup path, setuppath\samples\2.5D.

Graphing Parametric Function

To create a graph of parametric function, you should select item two in Form drop-down listbox in 2.5D Function Graph Properties dialogbox.

Examples:
Some 2.5D examples are provided. You can find them in a directory in your setup path, setuppath\samples\2.5D.
