Location of the gauge needle, specified as any numeric value.

Changing the Limits property value has no effect on the Value property setting.

Example: 60

Minimum and maximum gauge scale values, specified as a two-element numeric array. The first value in the array must be less than the second value.

If you change Limits such that the Value property is less than the new lower limit, or more than the new upper limit, then the gauge needle points to a location off the scale.

For example, suppose Limits is [0 100] and the Value property is 20. If the Limits changes to [50 100], then the needle points to a location off the scale, slightly less than 50.

Orientation of the gauge, specified as one of the following:

'north'
'south'
'east'
'west'

Direction of the gauge scale, specified as one of the following:

Scale colors, specified as one of the following arrays:

RGB triplets and hexadecimal color codes are useful for specifying custom colors.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB^® uses in many types of plots.

Each color of the ScaleColors array corresponds to a colored section of the gauge. Set the ScaleColorLimits property to map the colors to specific sections of the gauge.

If you do not set the ScaleColorLimits property, MATLAB distributes the colors equally over the range of the gauge.

Scale color limits, specified as a n-by-2 array of numeric values. For every row in the array, the first element must be less than the second element.

When applying colors to the gauge, MATLAB applies the colors starting with the first color in the ScaleColors array. Therefore, if two rows in ScaleColorLimits array overlap, then the color applied later takes precedence.

The gauge does not display any portion of the ScaleColorLimits that fall outside of the Limits property.

If the ScaleColors and ScaleColorLimits property values are different sizes, then the gauge shows only the colors that have matching limits. For example, if the ScaleColors array has three colors, but the ScaleColorLimits has only two rows, then the gauge displays the first two color/limit pairs only.

Major tick mark locations, specified as a vector of numeric values or an empty vector. If you do not want to show major tick marks, specify this property as an empty vector.

Tick locations that are outside the range of the Limits property do not display.

MATLAB removes duplicate tick values. However, if a major tick falls on the same value as a minor tick, only the major tick displays.

Setting the MajorTicks property sets the MajorTicksMode property to 'manual'.

Major tick creation mode, specified as one of the following:

Major tick labels, specified as a cell array of character vectors, string array, or 1-D categorical array. If you do not want to show tick labels, specify this property as an empty cell array. If you want to remove a label from a specific tick mark, specify an empty character vector or empty string scalar for the corresponding element in the MajorTickLabels array. If you specify this property as a categorical array, MATLAB uses the values in the array, not the full set of categories.

If the length of the MajorTickLabels array is different from the length of the MajorTicks vector, MATLAB ignores the extra entries of the longer array. If there are extra labels, they are ignored. If there are extra tick marks, they display without labels.

Setting MajorTickLabels changes the MajorTickLabelsMode value to 'manual'.

Major tick labels mode, specified as one of the following:

Minor tick mark locations, specified as a vector of numeric values or an empty vector. If you do not want to show minor tick marks, specify this property as an empty vector.

Tick locations that are outside the range of the Limits property do not display.

MATLAB removes duplicate tick values. However, if a minor tick falls on the same value as a major tick, only the major tick displays.

Setting the MinorTicks property value sets the MinorTicksMode property value to 'manual'.

Minor tick creation mode, specified as one of the following:

Font name, specified as a system supported font name. The default font depends on the specific operating system and locale.

If the specified font is not available, then MATLAB uses the best match among the fonts available on the system where the app is running.

Example: 'Arial'

Font size, specified as a positive number. The units of measurement are pixels. The default font size depends on the specific operating system and locale.

Example: 14

Font weight, specified as one of these values:

Not all fonts have a bold font weight. For fonts that do not, specifying 'bold' results in the normal font weight.

Font angle, specified as 'normal' or 'italic'. Not all fonts have an italic font angle. For fonts that do not, specifying 'italic' results in the normal font angle.

Font color, specified as an RGB triplet, a hexadecimal color code, or one of the options listed in the table.

RGB triplets and hexadecimal color codes are useful for specifying custom colors.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots.

Background color, specified as an RGB triplet, a hexadecimal color code, or one of the color options listed in the table.

RGB triplets and hexadecimal color codes are useful for specifying custom colors.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots.

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.

To make your app start faster, set the Visible property to 'off' for all UI components that do not need to appear at startup.

Operational state of gauge, 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.

Tooltip, specified as a character vector, cell array of character vectors, string array, or 1-D categorical array. Use this property to display a message when the user hovers the pointer over the component at run time. The tooltip displays even when the component is disabled. To display multiple lines of text, specify a cell array of character vectors or a string array. Each element in the array becomes a separate line of text. If you specify this property as a categorical array, MATLAB uses the values in the array, not the full set of categories.

Context menu, specified as a ContextMenu object created using the uicontextmenu function. Use this property to display a context menu when you right-click on a component.

Location and size of the gauge relative to the parent container, specified as the vector, [left bottom width height].

All measurements are in pixel units.

The Position values are relative to the drawable area of the parent container. The drawable area is the area inside the borders of the container and does not include the area occupied by decorations such as a menu bar or title.

Example: [100 100 100 20

Inner location and size of the gauge, specified as [left bottom width height]. Position values are relative to the parent container. All measurements are in pixel units. This property value is identical to the Position property.

This property is read-only.

Outer location and size of the gauge, returned as [left bottom width height]. Position values are relative to the parent container. All measurements are in pixel units. This property value is identical to Position property.

Layout options, specified as a GridLayoutOptions object. This property specifies options for components that are children of grid layout containers. If the component is not a child of a grid layout container (for example, it is a child of a figure or panel), then this property is empty and has no effect. However, if the component is a child of a grid layout container, you can place the component in the desired row and column of the grid by setting the Row and Column properties on the GridLayoutOptions object.

For example, this code places a semicircular gauge in the third row and second column of its parent grid.

g = uigridlayout([4 3]);
gauge = uigauge(g,'semicircular');
gauge.Layout.Row = 3;
gauge.Layout.Column = 2;

To make the gauge span multiple rows or columns, specify the Row or Column property as a two-element vector. For example, this gauge spans columns 2 through 3:

gauge.Layout.Column = [2 3];

Object creation function, specified as one of these values:

For more information about specifying a callback as a function handle, cell array, or character vector, see Callbacks in App Designer.

This property specifies a callback function to execute when MATLAB creates the object. MATLAB initializes all property values before executing the CreateFcn callback. If you do not specify the CreateFcn property, then MATLAB executes a default creation function.

Setting the CreateFcn property on an existing component has no effect.

If you specify this property as a function handle or cell array, you can access the object that is being created using the first argument of the callback function. Otherwise, use the gcbo function to access the object.

Object deletion function, specified as one of these values:

For more information about specifying a callback as a function handle, cell array, or character vector, see Callbacks in App Designer.

This property specifies a callback function to execute when MATLAB deletes the object. MATLAB executes the DeleteFcn callback before destroying the properties of the object. If you do not specify the DeleteFcn property, then MATLAB executes a default deletion function.

If you specify this property as a function handle or cell array, you can access the object that is being deleted using the first argument of the callback function. Otherwise, use the gcbo function to access the object.

Callback interruption, 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.

This property determines if a running callback can be interrupted. There are two callback states to consider:

MATLAB determines callback interruption behavior whenever it executes a command that processes the callback queue. These commands include drawnow, figure, uifigure, getframe, waitfor, and pause.

If the running callback does not contain one of these commands, then no interruption occurs. MATLAB first finishes executing the running callback, and later executes the interrupting callback.

If the running callback does contain one of these commands, then the Interruptible property of the object that owns the running callback determines if the interruption occurs:

Callback queuing, specified as 'queue' or 'cancel'. The BusyAction property determines how MATLAB handles the execution of interrupting callbacks. There are two callback states to consider:

The BusyAction property determines callback queuing behavior only when both of these conditions are met:

Under these conditions, the BusyAction property of the object that owns the interrupting callback determines how MATLAB handles the interrupting callback. These are possible values of the BusyAction property:

This property is read-only.

Deletion status, returned as an on/off logical value of type matlab.lang.OnOffSwitchState.

MATLAB sets the BeingDeleted property to 'on' when the DeleteFcn callback begins execution. The BeingDeleted property remains set to 'on' until the component object no longer exists.

Check the value of the BeingDeleted property to verify that the object is not about to be deleted before querying or modifying it.

Parent container, specified as a Figure object created using the uifigure function, or one of its child containers: Tab, Panel, ButtonGroup, or GridLayout. If no container is specified, MATLAB calls the uifigure function to create a new Figure object that serves as the parent container.

Visibility of the object handle, specified as 'on', 'callback', or 'off'.

This property controls the visibility of the object in its parent's list of children. When an object is not visible in its parent's list of children, it is not returned by functions that obtain objects by searching the object hierarchy or querying properties. These functions include get, findobj, clf, and close. Objects are valid even if they are not visible. If you can access an object, you can set and get its properties, and pass it to any function that operates on objects.

This property is read-only.

Type of graphics object, returned as 'uisemicirculargauge'.

Object identifier, specified as a character vector or string scalar. You can specify a unique Tag value to serve as an identifier for an object. When you need access to the object elsewhere in your code, you can use the findobj function to search for the object based on the Tag value.

User data, specified as any MATLAB array. For example, you can specify a scalar, vector, matrix, cell array, character array, table, or structure. Use this property to store arbitrary data on an object.

If you are working in App Designer, create public or private properties in the app to share data instead of using the UserData property. For more information, see Share Data Within App Designer Apps.
