Getting Started

Setting Plot Preferences and Properties

The Control System Toolbox provides three graphical user interfaces (GUIs) that give you control over the visualization of time and frequency plots generated by the toolbox:

• Toolbox Preferences
• Tool Preferences
• Plot Properties

Preferences refer to global options that you can save from session to session or to any LTI Viewer or SISO Design Tool that you open during a single session. Properties are options that apply only to the current window. This section gives an overview of the three GUI's; see the online help system for a complete descriptions

Although you can set plot properties in any response plot, you can use the Toolbox Preferences Editor to set properties for any response plot the Control System Toolbox generates. This figure shows the inheritance hierarchy from toolbox preference to plot properties.

You can activate preference and plot editors by doing the following:

• Toolbox preferences -- Select Toolbox Preferences under File in either the LTI Viewer or the SISO Design Tool.
• Tool preferences -- Select SISO Tool Preferences under Edit for the SISO Design Tool and Viewer Preferences under Edit in the LTI Viewer.
• Plot properties -- Double-click on any response plot created by the Control System Toolbox or select Properties from the right-click menus.

For a complete discussion of how to use property and preference editors, see Customization" in the online help under Control System Toolbox.
