Coordinate System

Cartesian Graphs

To create a function graph in 2D Cartesian coordinate system, following these steps:

1. If graphs created before are 2.5D or 3D, select File->New->2D Graph from the menus, or click button in Standard toolbar.
2. Select Draw->2D Function Graph->Cartesian from the menus, or click button in Plot toolbar to open 2D 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 2D 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 2D examples are provided. You can find them in a directory in your setup path, setuppath\samples\2D.

Polar Graphs

To create a function graph in 2D polar coordinate system, following these steps:

1. If graphs created before are 2.5D or 3D, select File->New->2D Graph from the menus, or click button in Standard toolbar.
2. Select Draw->2D Function Graph->Polar from the menus, or click button in Plot toolbar to open 2D 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 2D 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.
