BubbleLegend Properties

Bubble legend appearance and behavior

Since R2020b

BubbleLegend properties control the appearance and behavior of a BubbleLegend object. By changing property values, you can modify certain aspects of the legend. Use dot notation to query and set properties.

blgd = bubblelegend;
blgd.Style = 'telescopic';

Position and Layout

expand all

Location with respect to the axes, specified as one of the location values listed in this table.

ValueDescription
'north'Inside top edge of the axes.
'south'Inside bottom edge of the axes.
'east'Inside right edge of the axes.
'west'Inside left edge of the axes.
'northeast'Inside top-right corner of the axes.
'northwest'Inside top-left corner of the axes.
'southeast'Inside bottom-right corner of the axes.
'southwest'Inside bottom-left corner of the axes.
'northoutside'Above the axes.
'southoutside'Below the axes.
'eastoutside'To the right of the axes.
'westoutside'To the left of the axes.
'northeastoutside'Outside top-right corner of the axes.
'northwestoutside'Outside top-left corner of the axes.
'southeastoutside'Outside bottom-right corner of the axes.
'southwestoutside'Outside bottom-left corner of the axes
'layout'A tile in a tiled chart layout. To move the legend to a different tile, set the Layout property.
'none'A location determined by the Position property. Use the Position property to specify a custom location.

Custom location and size, specified as a four-element vector of the form [left bottom width height]. The first two values, left and bottom, specify the distance from the lower left corner of the figure to the lower left corner of the legend. The last two values, width and height, specify the legend dimensions. The Units property determines the position units.

If you specify the Position property, then MATLAB® automatically changes the Location property to 'none'.

Example: bubblelegend('Position',[0.2 0.6 0.1 0.2])

Note

Setting this property has no effect when the parent container is a TiledChartLayout object.

Position units, specified as one of the values in this table.

UnitsDescription
'normalized' (default)Normalized with respect to the container, which is usually the figure. The lower-left corner of the figure maps to (0,0) and the upper-right corner maps to (1,1). Resizing the figure updates the values of the Position vector.
'inches'Inches.
'centimeters'Centimeters.
'characters'

Based on the default system font character size.

  • Character width = width of letter x.

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

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

Pixels.

  • On Windows® systems, a pixel is 1/96th of an inch.

  • On Macintosh systems, a pixel is 1/72nd of an inch.

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

All units are measured from the lower-left corner of the container window.

This property affects the Position property. If you change the units, then it is good practice to return it to its default value after completing your computation to prevent affecting other functions that assume Units is the default value.

If you specify the Position and Units properties as Name,Value pairs when creating the object, then the order of specification matters. If you want to define the position with particular units, then you must set the Units property before the Position property.

Layout options, specified as a TiledChartLayoutOptions object. This property is useful when the legend is in a tiled chart layout.

To position the legend within the grid of a tiled chart layout, set the Tile property on the TiledChartLayoutOptions object. For example, consider a 3-by-3 tiled chart layout. The layout has a grid of tiles in the center, and four tiles along the outer edges. In practice, the grid is invisible and the outer tiles do not take up space until you populate them with axes or other objects.

Diagram of a 3-by-3 tiled chart layout.

This code places the legend lgd in the third tile of the grid..

lgd.Layout.Tile = 3;

To place the legend in one of the surrounding tiles, specify the Tile property as 'north', 'south', 'east', or 'west'. For example, setting the value to 'east' places the legend in the tile to the right of the grid.

lgd.Layout.Tile = 'east';

If the legend is not a child of a tiled chart layout (for example, if it is a child of the figure) then this property is empty and has no effect.

Labels

expand all

Legend title, returned as a legend text object. To add a legend title, set the String property of the legend text object. To change the title appearance, such as the font style or color, set legend text properties. For a list, see Text Properties.

blgd = bubblelegend;
blgd.Title.String = 'My Legend Title';
blgd.Title.FontSize = 12;

Alternatively, call the bubblelegend function and specify the title as the first argument. You can also create or change aspects of the title with the title function.

blgd = bubblelegend('My Legend Title');
title(blgd,'A Different Title','FontSize',12)

Limit labels, specified as a two- or three-element cell array of character vectors or string array. The first label appears next to the smallest bubble in the legend, and the last label appears next to the largest bubble. If you specify three labels, the second label does not display when the legend is horizontal or if the legend only has two bubbles. This table shows some common scenarios.

ExampleResult

Create a vertical legend with three bubbles, and specify three limit labels.

blgd = bubblelegend;
blgd.LimitLabels = {'Shortage','Abundance','Surplus'};

Vertical legend displaying all three labels.

Create a telescopic legend with three bubbles, and specify three limit labels.

blgd = bubblelegend('Style','telescopic');
blgd.LimitLabels = {'Shortage','Abundance','Surplus'};

Telescopic legend displaying all three labels.

Create a vertical legend with two bubbles, and specify three limit labels.

blgd = bubblelegend('NumBubbles',2);
blgd.LimitLabels = {'Shortage','Abundance','Surplus'};

Legend with two bubbles displaying two of the three labels.

Create a horizontal legend with three bubbles, and specify three limit labels.

blgd = bubblelegend('Style','horizontal');
blgd.LimitLabels = {'Shortage','Abundance','Surplus'};

Horizontal legend displaying two of the three labels.

Text interpreter, specified as one of these values:

  • 'tex' — Interpret characters using a subset of TeX markup.

  • 'latex' — Interpret characters using LaTeX markup.

  • 'none' — Display literal characters.

TeX Markup

By default, MATLAB supports a subset of TeX markup. Use TeX markup to add superscripts and subscripts, modify the font type and color, and include special characters in the text.

Modifiers remain in effect until the end of the text. Superscripts and subscripts are an exception because they modify only the next character or the characters within the curly braces. When you set the interpreter to 'tex', the supported modifiers are as follows.

ModifierDescriptionExample
^{ }Superscript'text^{superscript}'
_{ }Subscript'text_{subscript}'
\bfBold font'\bf text'
\itItalic font'\it text'
\slOblique font (usually the same as italic font)'\sl text'
\rmNormal font'\rm text'
\fontname{specifier}Font name — Replace specifier with the name of a font family. You can use this in combination with other modifiers.'\fontname{Courier} text'
\fontsize{specifier}Font size —Replace specifier with a numeric scalar value in point units.'\fontsize{15} text'
\color{specifier}Font color — Replace specifier with one of these colors: red, green, yellow, magenta, blue, black, white, gray, darkGreen, orange, or lightBlue.'\color{magenta} text'
\color[rgb]{specifier}Custom font color — Replace specifier with a three-element RGB triplet.'\color[rgb]{0,0.5,0.5} text'

This table lists the supported special characters for the 'tex' interpreter.

LaTeX Markup

To use LaTeX markup, set the interpreter to 'latex'. For inline mode, surround the markup with single dollar signs ($). For display mode, surround the markup with double dollar signs ($$).

LaTeX ModeExampleResult
Inline

'$\int_1^{20} x^2 dx$'

Equation with LaTeX inline mode

Display

'$$\int_1^{20} x^2 dx$$'

Equation with LaTeX display mode

The displayed text uses the default LaTeX font style. The FontName, FontWeight, and FontAngle properties do not have an effect. To change the font style, use LaTeX markup.

The maximum size of the text that you can use with the LaTeX interpreter is 1200 characters. For multiline text, this reduces by about 10 characters per line.

For examples that use TeX and LaTeX, see Greek Letters and Special Characters in Chart Text. For more information about the LaTeX system, see The LaTeX Project website at https://www.latex-project.org/.

Font

expand all

Font name, specified as a supported font name or "FixedWidth". To display and print text properly, you must choose a font that your system supports. The default font depends on your operating system and locale.

To use a fixed-width font that looks good in any locale, use "FixedWidth". The fixed-width font relies on the root FixedWidthFontName property. Setting the root FixedWidthFontName property causes an immediate update of the display to use the new font.

Font size, specified as a scalar value greater than zero in point units. The default font size depends on the specific operating system and locale.

If you change the axes font size, then MATLAB automatically sets the font size of the colorbar to 90% of the axes font size. If you manually set the font size of the colorbar, then changing the axes font size does not affect the colorbar font.

Character thickness, specified as 'normal' or 'bold'.

MATLAB uses the FontWeight property to select a font from those available on your system. Not all fonts have a bold weight. Therefore, specifying a bold font weight can still result in the normal font weight.

Character slant, specified as 'normal' or 'italic'.

Not all fonts have both font styles. Therefore, the italic font might look the same as the normal font.

Color and Styling

Legend style, specified as one of the values from the table. The images in the table show how a legend with three bubbles looks with the different styles.

Style ValueAppearance
'vertical'

Vertical style legend with three bubbles.

'horizontal'

Horizontal style legend with three bubbles.

'telescopic'

Telescopic style legend with three bubbles.

Number of bubbles to display in the legend, specified as 2 or 3. This table shows how a vertical bubble legend looks with 2 and 3 bubbles.

NumBubbles ValueAppearance
2

Vertical style legend with two bubbles.

3

Vertical style legend with three bubbles.

Order of the bubble sizes, specified as one of the values from the table. The table shows the effect of the different values on a vertical legend that has three bubbles.

BubbleSizeOrder ValueAppearance
'descending'

Vertical legend with descending order.

'ascending'

Vertical legend with ascending order.

Text color, specified as an RGB triplet, a hexadecimal color code, a color name, or a short name. The default color is black with a value of [0 0 0].

For a custom color, specify an RGB triplet or a hexadecimal color code.

  • An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1], for example, [0.4 0.6 0.7].

  • A hexadecimal color code is a string scalar or character vector that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Therefore, the color codes "#FF8800", "#ff8800", "#F80", and "#f80" are equivalent.

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

Display of box outline, 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 box around the legend.

  • 'off' — Do not display the box around the legend.

Width of box outline, specified as a positive value in point units. One point equals 1/72 inch.

Example: 1.5

Interactivity

expand all

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 object.

  • "off" — Hide the object without deleting it. You still can access the properties of an invisible object.

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

Note

If the PickableParts property is set to 'none' or if the HitTest property is set to 'off', then the context menu does not appear.

Selection state, 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' — Selected. If you click the object when in plot edit mode, then MATLAB sets its Selected property to 'on'. If the SelectionHighlight property also is set to 'on', then MATLAB displays selection handles around the object.

  • 'off' — Not selected.

Display of selection handles when selected, 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 selection handles when the Selected property is set to 'on'.

  • 'off' — Never display selection handles, even when the Selected property is set to 'on'.

Callbacks

expand all

Mouse-click callback, specified as one of these values:

  • Function handle

  • Cell array containing a function handle and additional arguments

  • Character vector that is a valid MATLAB command or function, which is evaluated in the base workspace (not recommended)

Use this property to execute code when you click the object. If you specify this property using a function handle, then MATLAB passes two arguments to the callback function when executing the callback:

  • Clicked object — Access properties of the clicked object from within the callback function.

  • Event data — Empty argument. Replace it with the tilde character (~) in the function definition to indicate that this argument is not used.

For more information on how to use function handles to define callback functions, see Create Callbacks for Graphics Objects.

Note

If the PickableParts property is set to 'none' or if the HitTest property is set to 'off', then this callback does not execute.

Object creation function, specified as one of these values:

  • Function handle.

  • Cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.

  • Character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

For more information about specifying a callback as a function handle, cell array, or character vector, see Create Callbacks for Graphics Objects.

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:

  • Function handle.

  • Cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.

  • Character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

For more information about specifying a callback as a function handle, cell array, or character vector, see Create Callbacks for Graphics Objects.

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 Execution Control

expand all

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:

  • The running callback is the currently executing callback.

  • The interrupting callback is a callback that tries to interrupt the running callback.

Whenever MATLAB invokes a callback, that callback attempts to interrupt a running callback. The Interruptible property of the object owning the running callback determines if interruption is permitted. The Interruptible property has two possible values:

  • A value of 'on' allows other callbacks to interrupt the object's callbacks. The interruption occurs at the next point where MATLAB processes the queue, such as when there is a drawnow, figure, uifigure, getframe, waitfor, or pause command.

    • If the running callback contains one of those commands, then MATLAB stops the execution of the callback at that point and executes the interrupting callback. MATLAB resumes executing the running callback when the interrupting callback completes.

    • If the running callback does not contain one of those commands, then MATLAB finishes executing the callback without interruption.

  • A value of 'off' blocks all interruption attempts. The BusyAction property of the object owning the interrupting callback determines if the interrupting callback is discarded or put into a queue.

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 running callback is the currently executing callback.

  • The interrupting callback is a callback that tries to interrupt the running callback.

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

  • The running callback contains a command that processes the callback queue, such as drawnow, figure, uifigure, getframe, waitfor, or pause.

  • The value of the Interruptible property of the object that owns the running callback is 'off'.

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:

  • 'queue' — Puts the interrupting callback in a queue to be processed after the running callback finishes execution.

  • 'cancel' — Does not execute the interrupting callback.

Ability to capture mouse clicks, specified as one of these values:

  • 'visible' — Capture mouse clicks when visible. The Visible property must be set to 'on' and you must click a part of the BubbleLegend object that has a defined color. You cannot click a part that has an associated color property set to 'none'. The HitTest property determines if the BubbleLegend object responds to the click or if an ancestor does.

  • 'none' — Cannot capture mouse clicks. Clicking the BubbleLegend object passes the click to the object below it in the current view of the figure window. The HitTest property of the BubbleLegend object has no effect.

Response to captured mouse clicks, 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' — Trigger the ButtonDownFcn callback of the BubbleLegend object. If you have defined the ContextMenu property, then invoke the context menu.

  • 'off' — Trigger the callbacks for the nearest ancestor of the BubbleLegend object that meets one of these conditions:

    • HitTest property is set to 'on'.

    • PickableParts property is set to a value that enables the ancestor to capture mouse clicks.

Note

The PickableParts property determines if the BubbleLegend object can capture mouse clicks. If it cannot, then the HitTest property has no effect.

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/Child

expand all

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

The BubbleLegend object must have the same parent as the associated axes. If you change the parent of the associated axes, then the BubbleLegend object automatically updates to use the same parent.

The object has no children. You cannot set this property.

Visibility of the object handle in the Children property of the parent, specified as one of these values:

  • "on" — Object handle is always visible.

  • "off" — Object handle is invisible at all times. This option is useful for preventing unintended changes by another function. Set HandleVisibility to "off" to temporarily hide the handle during the execution of that function.

  • "callback" — 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 at the command line, but permits callback functions to access it.

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

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

Identifiers

expand all

This property is read-only.

Type of graphics object, returned as 'bubblelegend'. Use this property to find all objects of a given type within a plotting hierarchy.

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.
