ColorBar Properties
Colorbar appearance and behavior
ColorBar
properties control the appearance
and behavior of a ColorBar
object. By changing
property values, you can modify certain aspects of the colorbar. Use dot notation to
refer to a particular object and property:
c = colorbar; w = c.LineWidth; c.LineWidth = 1.5;
Ticks and Labels
Ticks
— Tick mark locations
vector of monotonically increasing numeric values
Tick mark locations, specified as a vector of monotonically
increasing numeric values. The values do not need to be equally spaced.
If you do not want tick marks displayed, then set the property to
the empty vector, []
.
Example: [-1,0,1,2,3,4,5]
Data Types: single
| double
TicksMode
— Selection mode for Ticks
'auto'
(default) | 'manual'
Selection mode for Ticks
, specified as one of these values:
'auto'
— Automatically choose tick values.'manual'
— Manually specify tick values. To specify the tick values, set theTicks
property.
TickLabels
— Tick mark labels
cell array of character vectors | string array | numeric array | character vector | categorical array
Tick mark labels, specified as a cell array of character vectors, a string array, a numeric array, a character vector, or a categorical array. By default, the colorbar labels the tick marks with numeric values. If you specify labels and do not specify enough labels for all the tick marks, then MATLAB® cycles through the labels.
If you specify this property as a categorical array, MATLAB uses the values in the array, not the categories.
Example: {'cold','warm','hot'}
TickLabelsMode
— Selection mode for TickLabels
'auto'
(default) | 'manual'
Selection mode for TickLabels
, specified as one of
these values:
'auto'
— Automatically choose the tick labels.'manual'
— Manually specify tick labels. To specify the tick labels, set theTickLabels
property.
TickLabelInterpreter
— Tick label interpreter
'tex'
(default) | 'latex'
| 'none'
Tick label interpreter, specified as one of these values:
'tex'
— Interpret labels using a subset of the TeX markup.'latex'
— Interpret labels using a subset of LaTeX markup. When you specify the tick labels, use dollar signs around each element in the cell array.'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 text type and color, and include special characters in the labels.
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.

LaTeX Markup
To use LaTeX markup, set the TickLabelInterpreter
property to
'latex'
. Use dollar symbols around the labels, 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 within the text. The maximum size of
the text that you can use with the LaTeX interpreter is 1200 characters. For multiline text,
the maximum size of the text 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/.
Limits
— Minimum and maximum tick mark values
two-element vector
The minimum and maximum tick mark values, specified as a two-element vector. The second vector element must be greater than the first element.
Example: [0 1]
Data Types: single
| double
| int8
| int16
| int32
| int64
| uint8
| uint16
| uint32
| uint64
LimitsMode
— Selection mode for limits
'auto'
(default) | 'manual'
Selection mode for limits, specified as one of these values:
'auto'
— Automatically choose the limits.'manual'
— Use manually specified limits. To specify the limits, set theLimits
property.
Label
— Label
text object
Label that displays along the colorbar, returned as a text object. This text object
contains properties that control the label appearance and the text that displays. Use the
Label
property to access the text object, for
example:
c = colorbar; c.Label
ans = Text with properties: String: '' FontSize: 10 FontWeight: 'normal' FontName: 'Helvetica' Color: [0.1500 0.1500 0.1500] HorizontalAlignment: 'left' Position: [0 0 0] Units: 'data' Show all properties
To add a label, or change a label, set the String
property for the
text object, for
example:
c.Label.String = 'Label Text Goes Here';
To change the label appearance, such as the font style or color, set other text properties. For example, this code changes the font size.
c.Label.FontSize = 12;
For a full list of options, see Text Properties.
Direction
— Direction of color scale
'normal'
(default) | 'reverse'
Direction of color scale, specified as one of these values:
'normal'
— Display the colormap and labels ascending from bottom to top for a vertical colorbar, and ascending from left to right for a horizontal colorbar.'reverse'
— Display the colormap and labels descending from bottom to top for a vertical colorbar, and descending from left to right for a horizontal colorbar.
TickLength
— Tick mark length
0.01
(default) | scalar
Tick mark length, specified as a scalar. Specify the tick length as a fraction of the colorbar axis length.
Example: 0.05
Data Types: single
| double
| int8
| int16
| int32
| int64
| uint8
| uint16
| uint32
| uint64
TickDirection
— Tick mark direction
'in'
(default) | 'out'
Tick mark direction, specified as one of these values:
Value | Description | Result |
---|---|---|
'in' | Display the tick marks inside colorbar box. |
|
'out' | Display the tick marks outside the colorbar box. |
|
Font
FontName
— Font name
supported 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 size
scalar value greater than zero
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.
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.
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.
Position
Location
— Location with respect to the axes
'eastoutside'
(default) | 'north'
| 'south'
| 'east'
| 'west'
| 'northoutside'
| ...
Location with respect to the axes, specified as one of the values listed in this table.
Value | Resulting Location | Resulting Orientation |
---|---|---|
'north' | Top of axes | Horizontal |
'south' | Bottom of axes | Horizontal |
'east' | Right side of axes | Vertical |
'west' | Left side of axes | Vertical |
'northoutside' | Top outside of axes | Horizontal |
'southoutside' | Bottom outside of axes | Horizontal |
'eastoutside' | Right outside of axes (default) | Vertical |
'westoutside' | Left outside of axes | Vertical |
'manual' | Determined by Position property | Vertical |
'layout' | A tile in a tiled chart layout. To move the colorbar to a
different tile, set the Layout property of the
colorbar. | Depends on the shape of the tile |
To display the colorbar in a location that does not appear in
the table, use the Position
property to specify
a custom location. If you set the Position
property,
then MATLAB sets the Location
property to 'manual'
.
The associated axes does not resize to accommodate the colorbar when
the Location
property is set to 'manual'
.
AxisLocation
— Axis location
'out'
(default) | 'in'
Axis location, specified as one of the following values. Use this property to specify the location of the tick marks, tick labels, and colorbar label.
'out'
— Display the tick marks and labels on the side of the colorbar towards the outside of the figure. This is the default value.'in'
— Display the tick marks and labels on the side of the colorbar towards the inside of the figure.
AxisLocationMode
— Selection mode for AxisLocation
'auto'
(default) | 'manual'
Selection mode for AxisLocation
, specified as one of
these values:
'auto'
— Automatically choose the location.'manual'
— Use a manually specified location. To specify the location, set theAxisLocation
property.
Position
— Custom location and size
four-element vector
Custom location and size, specified as a four-element vector of the form
[left, bottom, width, height]
. The
left
and bottom
elements specify
the distance from the lower-left corner of the figure or to the lower-left
corner of the colorbar. The width
and
height
elements specify the dimensions of the
colorbar. The Units
property determines the position
units.
If you specify the Position
property, then
MATLAB changes the Location
property to
'manual'
. The associated axes does not resize to
accommodate the colorbar when the Location
property is
'manual'
.
Example: [0.1 0.1 0.3 0.7]
Note
Setting this property has no effect when the parent container is a
TiledChartLayout
object.
Units
— Position units
'normalized'
(default) | 'inches'
| 'centimeters'
| 'characters'
| 'points'
| 'pixels'
Position units, specified as one of the values in this table.
Units | Description |
---|---|
'normalized' (default) | Normalized with respect to the parent 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) . |
'inches' | Inches. |
'centimeters' | Centimeters. |
'characters' |
Based on the default system font character size.
|
'points' | Points. One point equals 1/72 inch. |
'pixels' | Pixels.
|
All units are measured from the lower-left corner of the parent container.
This property affects other properties, such as the Position
property. If
you change the units, then return the units to the default value after completing your
computation to prevent affecting other functions that assume 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. For example, to set the position in specific units, then you must
set the Units
property before the Position
property.
Layout
— Layout options
empty LayoutOptions
array (default) | TiledChartLayoutOptions
object
Layout options, specified as a TiledChartLayoutOptions
object. This property is useful when the colorbar is in a tiled chart
layout.
To position the colorbar 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.
This code places the colorbar cb
in the third tile of
the
grid..
cb.Layout.Tile = 3;
To place the colorbar 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 colorbar in the tile to the right
of the
grid.
cb.Layout.Tile = 'east';
If the colorbar 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.
Color and Styling
Color
— Color of tick marks, text, and box outline
[0 0 0]
(default) | RGB triplet | hexadecimal color code | 'r'
| 'g'
| 'b'
| ...
Color of the tick marks, text, and 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 string scalar or character vector that starts with a hash symbol (
#
) followed by three or six hexadecimal digits, which can range from0
toF
. 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.
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.
RGB Triplet | Hexadecimal Color Code | Appearance |
---|---|---|
[0 0.4470 0.7410] | "#0072BD" | |
[0.8500 0.3250 0.0980] | "#D95319" | |

Example: '#00FF00'
Box
— Box outline
'on'
(default) | on/off logical value
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 outline around the colorbar.'off'
— Do not display the box outline around the colorbar.
LineWidth
— Width of box outline

(default) | positive value
Width of box outline, specified as a positive value in point units. One point equals 1/72 inch.
Example: 1.5
Interactivity
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 object."off"
— Hide the object without deleting it. You still can access the properties of an invisible object.
ContextMenu
— Context menu
ContextMenu
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.
Selected
— Selection state
'off'
(default) | on/off logical value
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 itsSelected
property to'on'
. If theSelectionHighlight
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 value
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 theSelected
property is set to'on'
.'off'
— Never display selection handles, even when theSelected
property is set to'on'
.
Callbacks
ButtonDownFcn
— Mouse-click callback
''
(default) | function handle | cell array | character vector
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.
CreateFcn
— Creation function
''
(default) | function handle | cell array | character vector
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.
DeleteFcn
— Deletion function
''
(default) | function handle | cell array | character vector
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
Interruptible
— Callback interruption
'off'
(default) | on/off logical value
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 adrawnow
,figure
,uifigure
,getframe
,waitfor
, orpause
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. TheBusyAction
property of the object owning the interrupting callback determines if the interrupting callback is discarded or put into a queue.
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.
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:
'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) | 'none'
Ability to capture mouse clicks, specified as one of these values:
'visible'
— Capture mouse clicks only when visible. TheVisible
property must be set to'on'
. TheHitTest
property determines if theColorBar
object responds to the click or if an ancestor does.'none'
— Cannot capture mouse clicks. Clicking theColorBar
object passes the click to the object behind it in the current view of the figure window. TheHitTest
property of theColorBar
object has no effect.
HitTest
— Response to captured mouse clicks
'on'
(default) | on/off logical value
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 theButtonDownFcn
callback of theColorBar
object. If you have defined theContextMenu
property, then invoke the context menu.'off'
— Trigger the callbacks for the nearest ancestor of theColorBar
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 ColorBar
object can capture
mouse clicks. If it cannot, then the HitTest
property
has no effect.
BeingDeleted
— Deletion status
on/off logical value
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
Parent
— Parent container
Figure
object | Panel
object | Tab
object | TiledChartLayout
object
Parent container, specified as a Figure
object,
Panel
object, Tab
object, or a
TiledChartLayout
object.
The ColorBar
object must have the
same parent as the associated axes. If you change the parent of the associated axes,
then the ColorBar
object
automatically updates to use the same parent.
Children
— Children
empty GraphicsPlaceholder
array
The 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. SetHandleVisibility
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
Type
— Type of graphics object
'colorbar'
This property is read-only.
Type of graphics object, returned as 'colorbar'
.
Use this property to find objects in a hierarchy. For example, you can use
the findobj
function to find
objects that have a specific Type
property value.
Tag
— Object identifier
''
(default) | character vector | string scalar
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.
UserData
— User data
[]
(default) | array
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.
Version History
Introduced in R2014bR2020a: UIContextMenu
property is not recommended
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, but it is no
longer listed when you call the set
, get
, or
properties
functions on the ColorBar
object.
