InitialPlot properties control the appearance and behavior of initial condition plots created using the initialplot function. By changing property values, you can modify certain aspects of the plot.

ip = initialplot(sys);
ip.TransientTime.Visible = "on";

Response

expand all

Model responses, specified as an InitialResponse object or an array of such objects. Use this property to modify the dynamic system model or appearance for each response in the plot. Each InitialResponse object has these properties.

Source data for the response, specified as a structure with these fields.

Dynamic system, specified as a SISO or MIMO dynamic system model or array of dynamic system models. You can only use these types of state-space model:

  • Continuous-time or discrete-time numeric ss models.

  • Generalized or uncertain LTI models, such as genss or uss models. (Using uncertain models requires Robust Control Toolbox™ software.)

    • For tunable control design blocks, the function evaluates the model at its current value for both plotting and returning response data.

    • For uncertain control design blocks, the function plots the nominal value and random samples of the model. When you use output arguments, the function returns response data for the nominal model only.

  • Sparse state-space models, such as sparss and mechss models. You must specify final time tFinal for sparse state-space models.

  • Linear time-varying (ltvss) and linear parameter-varying (lpvss) models.

If sys is an array of models, the function plots the responses of all models in the array on the same axes.

Time steps at which to compute the response, specified as one of these values:

  • Positive scalar tFinal— Compute the response from t = 0 to t = tFinal.

  • Two-element vector [t0 tFinal] — Compute the response from t = t0 to t = tFinal. (since R2023b)

  • Vector Ti:dt:Tf— Compute the response for the time points specified in t.

    • For continuous-time systems, dt is the sample time of a discrete approximation to the continuous system.

    • For discrete-time systems with a specified sample time, dt must match the sample time property Ts of sys.

    • For discrete-time systems with an unspecified sample time (Ts = -1), dt must be 1.

  • [] — Automatically select time values based on system dynamics.

When you specify a time range using either tFinal or [t0 tFinal]:

  • For continuous-time systems, the function automatically determines the step size and number of points based on the system dynamics.

  • For discrete-time systems with a specified sample time, the function uses the sample time of sys as the step size.

  • For discrete-time systems with unspecified sample time (Ts = -1), the function interprets tFinal as the number of sampling periods to simulate with a sample time of 1 second.

Express t using the time units specified in the TimeUnit property of sys.

Baseline input signal value, specified as a scalar or vector.

  • For single-input systems, Bias is a scalar value.

  • For multi-input systems, Bias is a vector of length Nu, where Nu is the number of input channels. Each vector value corresponds to the signal value in that input channel. The functions compute the responses one input channel at a time.

  • For state-space models with offsets, set Bias = 'u0' to set the baseline signal to the offsets u0, u0(t) of the LTV model, or u0(t,p) of the LPV model. For LTV and LPV models, this is the u0 output of the data function. The total input signal is then u0 + u(t).

  • Operating condition obtained using findop.

  • Response configuration, specified as a RespConfig object. (since R2025a)

  • "on", 1, or true — Display the real component.

  • "off", 0, or false — Hide the real component.

The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Dependencies

  • This property applies only when ComplexViewType is "realimaginary".

  • This property is ignored for purely real systems.

Since R2025a

Option to display the imaginary component of responses for complex systems, specified as one of these logical on/off values:

  • "on", 1, or true — Display the imaginary component.

  • "off", 0, or false — Hide the imaginary component.

The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Dependencies

  • This property applies only when ComplexViewType is "realimaginary".

  • This property is ignored for purely real systems.

Chart Layout

expand all

Parent container of the chart, specified as one of these objects:

  • Figure

  • TiledChartLayout

  • UIFigure

  • UIGridLayout

  • UIPanel

  • UITab

Chart visibility, specified as one of these logical on/off values:

  • "on", 1, or true — Display the chart.

  • "off", 0, or false — Hide the chart without deleting it. You can still access the properties of chart when it is not visible.

The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Visibility of the chart object handle in the list of children for its parent, specified as one of these values:

  • 'on' — Chart object handle is always visible.

  • 'off' — Chart object handle is invisible at all times. This option is useful for preventing unintended changes to the chart by another function. To temporarily hide the handle during the execution of that function, set the HandleVisibility to 'off'.

  • 'callback' — Chart object handle is visible from within callbacks or functions invoked by callbacks, but not from within functions invoked from the command line. This option blocks access to the object in the Command Window, but it allows callback functions to access it.

Position units, specified as a value from the following table. To change the position of the chart in specific units, set the Units property before specifying the Position property. If you specify the Units and Position properties in a single command (using name-value pairs), be sure to specify Units before Position.

UnitsDescription
'normalized'Normalized with respect to the parent container, which is typically the figure, panel, or tab. The lower left corner of the container maps to (0,0), and the upper right corner maps to (1,1).
'inches'Inches
'centimeters'Centimeters
'characters'

Based on the default font of the graphics root object:

  • Character width = width of letter x.

  • Character height = distance between the baselines of two lines of text.

'points'Typography points. One point equals 1/72 inch.
'pixels'

On Windows® and Macintosh systems, the size of a pixel is 1/96th of an inch. This size is independent of your system resolution.

On Linux® systems, the size of a pixel is determined by your system resolution.

Chart size and location, including the margins for decorations such as axis labels and tick marks. Specify this property as a vector of form [left bottom width height]. The values are in the units specified by the Units property.

  • left — Distance from the left edge of the parent container to the outer-left edge of the chart that includes the margins. Typically, the parent container is a figure, panel, or tab.

  • bottom — Distance from the bottom edge of the parent container to the outer-bottom edge of the chart that includes the margins.

  • width — Width of chart, including the margins.

  • height — Height of chart, including the margins.

Note

Setting this property has no effect when the parent of the chart is a TiledChartLayout.

Chart size and location, excluding the margins for decorations such as axis labels and tick marks. Specify this property as a vector of form [left bottom width height]. The values are in the units specified by the Units property.

  • left — Distance from the left edge of the parent container to the inner-left edge of the chart that excludes the margins. Typically, the parent container is a figure, panel, or tab.

  • bottom — Distance from the bottom edge of the parent container to the inner-bottom edge of the chart that excludes the margins.

  • width — Width of the chart, excluding the margins.

  • height — Height of the chart, excluding the margins.

Note

Setting this property has no effect when the parent of the chart is a TiledChartLayout.

Chart size and location, excluding the margins for decorations such as axis labels and tick marks. Specify this property as a vector of form [left bottom width height]. This property is equivalent to the InnerPosition property.

Note

Setting this property has no effect when the parent of the chart is a TiledChartLayout.

Position property to hold constant when adding, removing, or changing decorations, specified as one of these values:

  • 'outerposition' — The OuterPosition property remains constant when you add, remove, or change decorations such as a title or an axis label. If any positional adjustments are needed, MATLAB® adjusts the InnerPosition property.

  • 'innerposition' — The InnerPosition property remains constant when you add, remove, or change decorations such as a title or an axis label. If any positional adjustments are needed, MATLAB adjusts the OuterPosition property.

Note

Setting this property has no effect when the parent of the chart is a TiledChartLayout.

Layout options, specified as a TiledChartLayoutOptions object or GridLayoutOptions object. This property specifies options when an instance of your chart is a child of a tiled chart layout or gridded layout. If the instance is not a child of one of these layouts (for example, it is a child of a figure or panel), then this property is empty and has no effect. Otherwise, you can position the chart within the layout by configuring the layout options.

This code places chart object c into the third tile of a tiled chart layout and makes the chart span 2 rows and 3 columns.

c.Layout.Tile = 3;
c.Layout.TileSpan = [2 3];

This code places chart object c into row 2 of a gridded layout and makes the chart span columns 3 and 4.

c.Layout.Row = 2;
c.Layout.Column = [3 4];

Properties to reset when adding a new plot to the chart, specified as one of these values:

  • 'add' — Add new plots to the existing chart. Do not delete existing plots or reset axes properties before displaying the new plot.

  • 'replace' — Delete existing plots and reset chart properties, except Position and Units, to their default values before displaying the new plot.
