Axes text appearance and behavior
Text
properties control the appearance and
behavior of a Text
object. By changing property
values, you can modify certain aspects of the text. Use dot notation to query and set
properties.
t = text(0.5,0.5,'text here'); s = t.FontSize; t.FontSize = 12;
String
— Text to display''
(default) | character vector | cell array of character vectors | string array | categorical array | numeric valueText to display, specified as a character vector, cell array of character vectors, string array, categorical array, or numeric value. Specify a value according to how you want the text to appear. This table lists the most common situations.
Appearance of Text | Description of Value | Example |
---|---|---|
One line of text | Character vector or 1-by-1 string array. | str = 'My Text' str = "My Text" |
Multiple lines of text | Cell array of character vectors or a string array. | str = {'First line','Second line'}; str = ["First line", "Second line"]; |
Text that includes a numeric variable | Array that includes the number converted to a
char array. Use num2str to convert
the value. |
x = 42;
str = ['The value is ',num2str(x)]; |
Text that includes special characters such as Greek letters or mathematical symbols | Array that includes TeX markup. For a list of supported markup,
see the Interpreter property. |
str = 'x ranges from 0 to 2\pi' |
Note
The words default
, factory
, and
remove
are reserved words that do not appear in text
when quoted as normal characters. To display any of these words
individually, precede them with a backslash, such as
'\default'
or '\remove'
.
If you specify this property as a categorical array, MATLAB® uses the values in the array, not the categories.
If you specify text that contains only a numeric value, the value is
converted using sprintf('%g',value)
. For example,
12345678
displays as
1.23457e+07
.
Color
— Text color[0 0 0]
(default) | RGB triplet | hexadecimal color code | 'r'
| 'g'
| 'b'
| ...Text color, specified as an RGB triplet, a hexadecimal color code, a color name, or a short
name. The default value of [0 0 0]
corresponds to black.
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 character vector or a string
scalar 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. Thus, 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.
Color Name | Short Name | RGB Triplet | Hexadecimal Color Code | Appearance |
---|---|---|---|---|
'red' | 'r' | [1 0 0] | '#FF0000' | |
'green' | 'g' | [0 1 0] | '#00FF00' | |
'blue' | 'b' | [0 0 1] | '#0000FF' | |
'cyan'
| 'c' | [0 1 1] | '#00FFFF' | |
'magenta' | 'm' | [1 0 1] | '#FF00FF' | |
'yellow' | 'y' | [1 1 0] | '#FFFF00' | |
'black' | 'k' | [0 0 0] | '#000000' | |
'white' | 'w' | [1 1 1] | '#FFFFFF' | |
'none' | Not applicable | Not applicable | Not applicable | No color |
Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots.

Interpreter
— Text interpreter'tex'
(default) | 'latex'
| 'none'
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.
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.
Modifier | Description | Example |
---|---|---|
^{ } | Superscript | 'text^{superscript}' |
_{ } | Subscript | 'text_{subscript}' |
\bf | Bold font | '\bf text' |
\it | Italic font | '\it text' |
\sl | Oblique font (usually the same as italic font) | '\sl text' |
\rm | Normal font | '\rm text' |
\fontname{ | Font name — Replace
with the name of
a font family. You can use this in combination with other modifiers. | '\fontname{Courier} text' |
\fontsize{ | Font size —Replace
with a numeric
scalar value in point units. | '\fontsize{15} text' |
\color{ | Font color — Replace
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
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.

To use LaTeX markup, set the interpreter to 'latex'
. Use dollar
symbols around the text, for example, use '$\int_1^{20} x^2 dx$'
for inline mode or '$$\int_1^{20} x^2 dx$$'
for 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 more information about the LaTeX system, see The LaTeX Project website at https://www.latex-project.org/.
FontName
— Font name'FixedWidth'
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.
FontSize
— Font sizeFont size, specified as a scalar value greater than zero in point units. The default font
size depends on the specific operating system and locale. One point equals
1/72
inch. To change the font units, use the
FontUnits
property.
Example: 12
Data Types: single
| double
| int8
| int16
| int32
| int64
| uint8
| uint16
| uint32
| uint64
FontWeight
— Character thickness'normal'
(default) | 'bold'
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.
FontAngle
— Character slant'normal'
(default) | 'italic'
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.
FontUnits
— Font size units'points'
(default) | 'inches'
| 'centimeters'
| 'normalized'
| 'pixels'
Font size units, specified as one of the values in this table.
Units | Description |
---|---|
'points' | Points. One point equals 1/72 inch. |
'inches' | Inches. |
'centimeters' | Centimeters. |
'normalized'
| Interpret font size as a fraction of the axes plot
box height. If you resize the axes, the font size
modifies accordingly. For example, if the
FontSize is
0.1 in normalized units, then the
text is 1/10 of the plot box height. |
'pixels' | Pixels. Starting in R2015b, distances in pixels are independent of your system resolution on Windows® and Macintosh systems:
On Linux® systems, the size of a pixel is determined by your system resolution. |
If you set both the font size and the font units in one function call, you
must set the FontUnits
property first so that the axes
correctly interprets the specified font size.
FontSmoothing
— Smooth font character appearance'on'
(default) | on/off logical valueSmooth font character appearance, 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'
— Apply font smoothing. Reduce
the appearance of jaggedness in the text characters to make the
text easier to read.
'off'
— Do not apply font
smoothing.
Rotation
— Text orientation0
(default) | scalar value in degreesText orientation, specified as a scalar value in degrees. The default
rotation of 0 degrees makes the text horizontal. For vertical text, set this
property to 90
or -90
. Positive values
rotate the text counterclockwise. Negative values rotate the text clockwise.
Example: 90
Example: -90

EdgeColor
— Color of box outline'none'
(default) | RGB triplet | hexadecimal color code | 'r'
| 'g'
| 'b'
| ...Color of box outline, specified as an RGB triplet, a hexadecimal color code, a color name, or a short name.
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 character vector or a string
scalar 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. Thus, 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.

Margin
— Space around text within the text box3
(default) | scalar numeric valueThe space around the text within the text box, specified as scalar numeric value in point units.
MATLAB uses the Extent
property value plus the
Margin
property value to determine the size of the
text box.
Example: 8

Clipping
— Clipping to axes plot box'off'
(default) | on/off logical valueClipping of the text to the axes plot box, 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'
— Clips the text to the axes
plot box.
If the axes ClippingStyle
property is set to '3dbox'
, which
is the default, then MATLAB either displays the entire text or
none of the text, depending on the text position. If
the point defined by the text
Position
property lies inside
the axes, then MATLAB displays the entire text. If the point
lies outside the axes, then MATLAB displays none of it.
If the axes ClippingStyle
property is set to 'rectangle'
,
then MATLAB displays portions of the text lying
inside the axes plot box and does not display
portions of the text lying outside the axes plot
box.
'off'
— Do not clip the text.
Portions of it might appear outside the axes plot box.
Note
If the Clipping
property of the associated
axes is set to 'on'
, which is the default, then
each individual object controls its own clipping behavior. If the
Clipping
property of the axes is set to
'off'
, then MATLAB does not clip any objects in the axes, regardless of
the Clipping
property of the individual
object.
Position
— Location of text[0 0 0]
(default) | two-element vector of form [x y]
| three-element vector of form [x y z]
Location of the text, specified as a two-element vector of the
form [x y]
or a three-element vector of the form [x
y z]
. If you omit the third element, z
,
then MATLAB sets it to 0
.
Specify the position using numeric values. To convert datetime
or duration values to the appropriate numeric values for a particular
coordinate direction, see ruler2num
.
By default, the position value is defined in data units. To
change the units, use the Units
property.
Example: [0.5 0.5 0]
Data Types: double

Extent
— Size and location of rectangle that encloses textThis property is read-only.
Size and location of the rectangle that encloses the text, not including
the margin, returned as a four-element vector of the form [left
bottom width height]
. The first two elements,
left
and bottom
, define the
position of the lower left corner of the rectangle. The last two elements,
width
and height
, define the
dimensions of the rectangle.
By default, the extent value is defined in data units. To change the
units, use the Units
property.
Example: [0.5 0.5 0.4 0.2]
Units
— Position and extent units'data'
(default) | 'normalized'
| 'inches'
| 'centimeters'
| 'characters'
| 'points'
| 'pixels'
Position units, specified as one of the values in this table.
Units | Description |
---|---|
'data' (default) | Data coordinates. |
'normalized' | Normalized with respect to the axes. The lower left corner
of the axes maps to (0,0) and the upper right corner
maps to (1,1) . |
'inches' | Inches. |
'centimeters' | Centimeters. |
'characters' |
Based on the default system font character size.
|
'points' | Points. One point equals 1/72 inch. |
'pixels' | Pixels. Starting in R2015b, distances in pixels are independent of your system resolution on Windows and Macintosh systems:
On Linux systems, the size of a pixel is determined by your system resolution. |
All units, except for 'data'
, are measured
from the lower left corner of the axes. This property affects the Position
and Extent
properties.
If you specify the Position
and Units
properties
as Name,Value
pairs when creating the Text
object,
then the order of specification matters. To define the position with
particular units, set the Units
property before
the Position
property.
HorizontalAlignment
— Horizontal alignment of text with respect to position point'left'
(default) | 'center'
| 'right'
Horizontal alignment of the text with respect to the x
value
in the Position
property, specified as one of the
values in this table. The vertical line indicates where the x
value
lies in relation to the text.
Value | Result |
---|---|
'left' (default) |
|
'center' |
|
'right' |
|
VerticalAlignment
— Vertical alignment of text with respect to position point'middle'
(default) | 'top'
| 'bottom'
| 'baseline'
| 'cap'
Vertical alignment of the text with respect to the y
value
in the Position
property, specified as one of the
values in this table. The horizontal line indicates where the y
value
lies in relation to the text.
Value | Result |
---|---|
'middle' |
|
'top' |
|
'cap' |

Editing
— Interactive edit mode'off'
(default) | on/off logical valueInteractive edit mode, 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'
— Allow interactive text
editing. MATLAB places an insert cursor within the text and typing
changes the text. To apply the new text, do any of the following:
Press the Esc key.
Click anywhere away from the text.
Reset the Editing
property to
'off'
.
MATLAB updates the String
property
to contain the new text and resets the
Editing
property to
'off'
.
'off'
— Do no allow interactive text
editing. To change the text, you must set the
String
property. This is the default
value.
Visible
— State of visibility'on'
(default) | on/off logical valueState 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.
ContextMenu
— Context menuGraphicsPlaceholder
array (default) | ContextMenu
objectContext 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.
Selected
— Selection state'off'
(default) | on/off logical valueSelection 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.
SelectionHighlight
— Display of selection handles'on'
(default) | on/off logical valueDisplay 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'
.
ButtonDownFcn
— Mouse-click callback''
(default) | function handle | cell array | character vectorMouse-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 Callback Definition.
Note
If the PickableParts
property is set to 'none'
or
if the HitTest
property is set to 'off'
,
then this callback does not execute.
CreateFcn
— Creation function''
(default) | function handle | cell array | character vectorObject 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 Callback Definition.
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.
DeleteFcn
— Deletion function''
(default) | function handle | cell array | character vectorObject 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 Callback Definition.
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.
Interruptible
— Callback interruption'on'
(default) | on/off logical valueCallback 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 the running
callback (if one exists). The Interruptible
property of the object
owning the running callback determines if interruption is allowed.
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.
Note
Callback interruption and execution behave differently in these situations:
If the interrupting callback is a DeleteFcn
, CloseRequestFcn
or SizeChangedFcn
callback, then the interruption occurs regardless of the Interruptible
property value.
If the running callback is currently executing the waitfor
function, then the interruption occurs regardless of the Interruptible
property value.
Timer
objects execute according to schedule regardless of the Interruptible
property value.
When an interruption occurs, MATLAB does not save the state of properties or the display. For example, the
object returned by the gca
or gcf
command might change when
another callback executes.
BusyAction
— Callback queuing'queue'
(default) | 'cancel'
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.
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. If interruption is not permitted, then the BusyAction
property of the object owning the interrupting callback determines if it is discarded or put in the queue. 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.
PickableParts
— Ability to capture mouse clicks'visible'
(default) | 'all'
| 'none'
Ability to capture mouse clicks, specified as one of these values:
'visible'
— Capture mouse clicks only when
visible. The Visible
property must be set to
'on'
. The HitTest
property
determines if the Text
object responds to the click or if an ancestor does.
'all'
— Capture mouse clicks regardless of
visibility. The Visible
property can be set to
'on'
or 'off'
. The
HitTest
property determines if the Text
object responds to
the click or if an ancestor does.
'none'
— Cannot capture
mouse clicks. Clicking the Text
object
passes the click to the object below it in the current view of the
figure window, which is typically the axes or the figure. The HitTest
property
has no effect.
If you want an object to be clickable when it is underneath
other objects that you do not want to be clickable, then set the PickableParts
property
of the other objects to 'none'
so that the click
passes through them.
HitTest
— Response to captured mouse clicks'on'
(default) | on/off logical valueResponse 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 Text
object. If you have
defined the ContextMenu
property, then invoke the
context menu.
'off'
— Trigger the callbacks for the nearest
ancestor of the Text
object that has one of these:
HitTest
property set to
'on'
PickableParts
property set to a value that
enables the ancestor to capture mouse clicks
Note
The PickableParts
property determines if
the Text
object can capture
mouse clicks. If it cannot, then the HitTest
property
has no effect.
BeingDeleted
— Deletion statusThis 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
— ParentAxes
object | PolarAxes
object | Group
object | Transform
objectParent, specified as an Axes
, PolarAxes
, Group
, or Transform
object.
Children
— ChildrenGraphicsPlaceholder
arrayThe object has no children. You cannot set this property.
HandleVisibility
— Visibility of object handle'on'
(default) | 'off'
| 'callback'
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 the
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.
Type
— Type of graphics object'text'
This property is read-only.
Type of graphics object, returned as 'text'
. Use this
property to find all objects of a given type within a plotting hierarchy,
for example, searching for the type using findobj
.
Tag
— Object identifier''
(default) | character vector | string scalarObject 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.
UserData
— User data[]
(default) | arrayUser 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.
UIContextMenu
property is not recommendedNot recommended starting in R2020a
Starting in R2020a, setting or getting UIContextMenu
property is not
recommended. Instead, use the ContextMenu
property, which accepts the same type of input and behaves the
same way as the UIContextMenu
property.
There are no plans to remove the UIContextMenu
property at this time, but
it is no longer listed when you call the set
, get
,
or properties
functions on the Text
object.
