StepPlot Properties

Access step plot properties

Since R2024b

StepPlot properties control the appearance and behavior of step plots created using stepplot. By changing property values, you can modify certain aspects of the plot.

sp = stepplot(sys);
sp.Characteristics.PeakResponse.Visible = "on";

For more information, see Customize Linear Analysis Plots at Command Line (Control System Toolbox).

Response

expand all

Model responses, specified as a StepResponse 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 StepResponse object has these properties.

Dynamic system, specified as a SISO or MIMO dynamic system model or an array of dynamic system models.

When you initially create a plot, Model matches the value you specify for sys.

Before R2026a: Specify the dynamic system using the Responses.SourceData.Model property.

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 size of the time step 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.

If you specify a step delay td using config, the function applies the step at t = t0+td.

Before R2026a: Specify time values using the Responses.SourceData.TimeSpec property.

Response configuration options, specified as a RespConfig object.

Before R2026a: Specify response configuration options using the Responses.SourceData.Config property.

LPV model parameter trajectory, specified as a matrix or a function handle.

  • For exogenous or explicit trajectories, specify Parameter as a matrix with dimensions N-by-Np, where N is the number of time samples and Np is the number of parameters.

    Thus, the row vector p(i,:) contains the parameter values at the ith time step.

  • For endogenous or implicit trajectories, specify p as a function handle of the form p = F(t,x,u) in continuous time and p = F(k,x,u) in discrete time that gives parameters as a function of time t or time sample k, state x, and input u.

    This option is useful when you want to simulate quasi-LPV models.

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

  • "on", 1, or true — Display the response in the plot.

Series index, specified as a positive integer or "none".

By default, the SeriesIndex property is a number that corresponds to the order in which the response was added to the chart, starting at 1. MATLAB® uses the number to calculate indices for automatically assigning color, line style, or markers for responses. The indices refer to the rows of the arrays stored in the ColorOrder and LineStyleOrder, and MarkerStyleOrder properties of the parent chart. Any responses in the chart that have the same SeriesIndex number also have the same color, line style, and markers.

A SeriesIndex value of "none" indicates that a response does not participate in the indexing scheme.

Multiple Responses

expand all

Since R2026a

Color order for creating responses, specified as a three-column matrix, where each row is an RGB triplet.

MATLAB assigns colors to responses according to their order of creation. The first response uses the first color, the second response uses the second color, and so on. If there are more responses than colors, then the cycle repeats.

You can change the color order for a chart object in either of these ways:

  • Set the ColorOrder property directly. In this case, you must specify the color array as a three-column matrix of RGB triplets. For example, the following command sets the color order to red, green, and blue.

    mychart.ColorOrder = [1 0 0;0 1 0;0 0 1];
  • Call the colororder function, specifying the chart object as the target. In this case, you can specify the colors using one of these methods:

    • Array of color names

      colororder(mychart,["red","green","blue"])
    • Array of hexadecimal codes

      colororder(mychart,["#FF0000","#00FF00","#0000FF"])
    • Palette name

      colororder(mychart,"gem12")

    For more information on setting color order, see colororder.

Since R2026a

Since R2026a

This property is read-only.

SeriesIndex value for the next response added to the chart, returned as a positive integer. This property is useful when you want to track how the responses cycle through the color, line, and marker styles. This property maintains a count of the objects in the axes that have a numeric SeriesIndex property value. MATLAB uses NextSeriesIndex to assign a SeriesIndex value to each new response. The count starts at 1 when you create the chart, and it increases by 1 for each response added to the chart.

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

  • "replace" — Delete existing responses and reset chart properties, except Position and Units, to their default values before displaying the new response.

  • "add" — Add new responses to the existing chart. Do not delete existing responses or reset axes properties before displaying the new response.

Position

expand all

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 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.

Units Description
'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.

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];

Visibility

expand all

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.

Parent

expand all

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

  • Figure

  • TiledChartLayout

  • UIFigure

  • UIGridLayout

  • UIPanel

  • UITab

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.
