P = timeoptions
P = timeoptions('cstprefs')
P = timeoptions returns a list of available options for time plots with default values set. You can use these options to customize the time value plot appearance from the command line.
P = timeoptions('cstprefs') initializes the plot options you selected in the Control System Toolbox Preferences Editor. For more information about the editor, see Toolbox Preferences Editor in the User's Guide documentation.
This table summarizes the available time plot options.
| Option | Description |
|---|---|
| Title, XLabel, YLabel | Label text and style |
| TickLabel | Tick label style |
| Grid [off|on] | Show or hide the grid |
| XlimMode, YlimMode | Limit modes |
| Xlim, Ylim | Axes limits |
| IOGrouping [none|inputs|output|all] | Grouping of input-output pairs |
| InputLabels, OutputLabels | Input and output label styles |
| InputVisible, OutputVisible | Visibility of input and output channels |
| Normalize [on|off] | Normalize responses |
| SettleTimeThreshold | Settling time threshold |
| RiseTimeLimits | Rise time limits |
In this example, enable the normalized response option before creating a plot.
P = timeoptions; % Set normalize response to on in options P.Normalize = 'on'; % Create plot with the options specified by P h = stepplot(tf(10,[1,1]),tf(5,[1,5]),P);
The following step plot is created with the responses normalized.

getoptions, impulseplot, initialplot, lsimplot, setoptions, stepplot
