VoltageVerificationChart

Chart for visualizing and comparing measured and simulated voltage data over time

Since R2025a

Description

Use VoltageVerificationChart to create a chart for visualizing and comparing the measured and simulated voltage data over time inside a voltage plot.

Creation

Description

Note

To quickly create a VoltageVerificationChart object, use the plot method of the ECM object. By using this function, you avoid importing the namespace, using the full class name, or dealing only with name-value arguments when creating the object.

To use this object, at the MATLAB^® Command Window, run this command at least once each MATLAB session:

import simscape.battery.parameters.*; 

All properties are exposed as name-value arguments in this object.

chart = VoltageVerificationChart(MeasuredVoltage=measVolt,SimulatedVoltage=simVolt) creates a VoltageVerificationChart object that visualizes the measured and simulated voltage data over time specified in the MeasuredVoltage and SimulatedVoltage arguments.

chart = VoltageVerificationChart(___,PropertyName=Value) creates a VoltageVerificationChart object and sets Properties using one or more name-value arguments.

Input Arguments

measVolt — Measured voltage

timetable

Measured voltage to plot, specified as a timetable.

simVolt — Simulated voltage

timetable

Simulated voltage to plot, specified as a timetable.

Output Arguments

chart — Chart for visualizing the measured and simulated voltage

VoltageVerificationChart object

Chart for visualizing the measured and simulated voltage in a voltage plot, returned as a VoltageVerificationChart object.

Properties

SimulatedVoltageVisible — Visibility of simulation voltage

"on" (default) | on/off logical value

Visibility of the simulation voltage, specified as "off", "on", or as numeric or logical 1 (true) or 0 (false). A value of "on" is equivalent to true, and "off" is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

AxesVisible — Visibility of chart axes

"on" (default) | on/off logical value

Visibility of the chart axes, specified as "off", "on", or as numeric or logical 1 (true) or 0 (false). A value of "on" is equivalent to true, and "off" is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

InnerPosition — Chart size and location, excluding margins

[left bottom width height]

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.

OuterPosition — Chart size and location, including margins

[left bottom width height]

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.

Position — Chart size and location, excluding margins

[left bottom width height]

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.

PositionConstraint — Position to hold constant

'outerposition' | 'innerposition'

Position property to hold constant when adding, removing, or changing decorations, specified as one of the following 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.

Units — Position units

'normalized' (default) | 'inches' | 'centimeters' | 'characters' | 'points' | 'pixels'

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' (default)	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'	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.

Layout — Layout options

empty LayoutOptions array (default) | TiledChartLayoutOptions

Layout options, specified as a TiledChartLayoutOptions object. This property specifies options when an instance of your chart is a child of a tiled chart layout. If the instance is not a child of a tiled chart layout (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 setting the Tile and TileSpan properties on the TiledChartLayoutOptions object.

For example, this code places chart object c into the third tile of a tiled chart layout.

c.Layout.Tile = 3;

To make the chart span multiple tiles, specify the TileSpan property as a two-element vector. For example, this chart spans 2 rows and 3 columns of tiles.

c.Layout.TileSpan = [2 3];

Note

Tiled chart layouts are not supported for the axes returned by the getAxes method. Instead, you can place an instance of your chart into a tiled chart layout.

Visible — State of visibility

'on' (default) | on/off logical value

State of visibility, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

• 'on' — Display the chart.

• 'off' — Hide the chart without deleting it. You still can access the properties of chart when it is not visible.

Parent — Parent container

Figure object (default) | Panel object | Tab object | TiledChartLayout object

Parent container of the chart, specified as a Figure, Panel, Tab, or TiledChartLayout object.

HandleVisibility — Visibility of object handle

'on' (default) | 'off'

Visibility of the chart object handle in its parent's list of children, 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.

If the object is not listed in the Children property of the chart's parent object, then functions that get object handles by searching the object hierarchy or querying handle properties cannot return it. This includes get, findobj, gca, gcf, gco, newplot, cla, clf, and close.

Hidden object handles are still valid. Set the root ShowHiddenHandles property to 'on' to list all object handles, regardless of their HandleVisibility property setting.
