Line Properties
Primitive line appearance and behavior
Line
properties control the appearance and behavior of a
Line
object. By changing property values, you can modify certain
aspects of the line chart.
h = line; h.LineStyle = ":";
Line
Color
— Line color
[0 0 0]
(default) | RGB triplet | hexadecimal color code | "r"
| "g"
| "b"
| ...
Line 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 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" | |

[0.6350 0.0780 0.1840] | "#A2142F" |
ColorMode
— Control how Color
is set
"auto"
(default) | "manual"
Control how the Color
property is set, specified as one of these values:
"auto"
— MATLAB controls the value of theColor
property by using theSeriesIndex
property of theLine
object and theColorOrder
property of the axes."manual"
— You set the value of theColor
property directly, or indirectly as a function argument when you create theLine
object.
If you change the value of the Color
property manually,
MATLAB changes the value of the ColorMode
property to
"manual"
.
LineStyle
— Line style
"-"
(default) | "--"
| ":"
| "-."
| "none"
Line style, specified as one of the options listed in this table.
Line Style | Description | Resulting Line |
---|---|---|
"-" | Solid line |
|
"--" | Dashed line |
|
":" | Dotted line |
|
"-." | Dash-dotted line |
|
"none" | No line | No line |
LineStyleMode
— Control how LineStyle
is set
"auto"
(default) | "manual"
Control how the LineStyle
property is set, specified as one of
these values:
"auto"
— MATLAB controls the value of theLineStyle
property by using theSeriesIndex
property of theLine
object and theLineStyleOrder
property of the axes."manual"
— You set the value of theLineStyle
property directly, or indirectly as a function argument when you create theLine
object.
If you change the value of the LineStyle
property manually,
MATLAB changes the value of the LineStyleMode
property to
"manual"
.
LineWidth
— Line width
0.5
(default) | positive value
Line width, specified as a positive value in points, where 1 point = 1/72 of an inch. If the line has markers, then the line width also affects the marker edges.
The line width cannot be thinner than the width of a pixel. If you set the line width to a value that is less than the width of a pixel on your system, the line displays as one pixel wide.
SeriesIndex
— Series index
positive whole number (default) | "none"
Series index, specified as a positive whole number or "none"
. This
property is useful for reassigning the colors, line styles, or markers of
Line
objects so that they match other objects.
By default, the SeriesIndex
property is a number that corresponds
to the order in which the Line
object was created, starting at
1
. MATLAB uses the number to calculate indices for automatically assigning color,
line style, or markers when you call plotting functions. The indices refer to the rows
of the arrays stored in the ColorOrder
and
LineStyleOrder
properties of the axes. Any objects in the axes
that have the same SeriesIndex
number also have the same color (and
line style and markers, if applicable).
A SeriesIndex
value of "none"
corresponds to a
solid line with a neutral color that does not participate in the indexing scheme.
How Manually Setting Colors, Line Styles, or Markers Overrides SeriesIndex
Behavior
To manually control the color, line style, and markers, set the
Color
, LineStyle
, and
Marker
properties of the Line
object.
When you manually set these properties of an object, MATLAB disables automatic color, line style, and marker selection for that
object and allows your selection to persist, regardless of the value of the
SeriesIndex
property. The ColorMode
,
LineStyleMode
, and MarkerMode
properties indicate whether the colors, line styles, and markers have been set
manually (by you) or automatically. For each of these mode properties, a value of
"manual"
indicates manual selection, and a value of
"auto"
indicates automatic selection.
To enable automatic selection again, set the ColorMode
,
LineStyleMode
, MarkerMode
, or all
three properties to "auto"
, and set the
SeriesIndex
property to a positive whole number.
In some cases, MATLAB sets the SeriesIndex
property to
0
, which also disables automatic selection.
LineJoin
— Style of line corners
"round"
(default) | "miter"
| "chamfer"
Style of line corners, specified as "round"
, "miter"
, or
"chamfer"
. This table illustrates the appearance of the different
values.
"round" | "miter" | "chamfer" |
---|---|---|
|
|
|
The appearance of the "round"
option might look different if the
Renderer
property of the figure is set to
"opengl"
instead of "painters"
.
AlignVertexCenters
— Sharp vertical and horizontal lines
'off'
(default) | on/off logical value
Sharp vertical and horizontal lines, 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
.
Value | Description | Appearance |
---|---|---|
'on' | Sharpen vertical and horizontal lines to eliminate an uneven appearance. |
|
'off' | Do not sharpen vertical or horizontal lines. The lines might appear uneven in thickness or color. |
|
If the associated figure has a GraphicsSmoothing
property set to 'on'
and a Renderer
property set to
'opengl'
, then the figure applies a smoothing technique to plots.
In some cases, this smoothing technique can cause vertical and horizontal lines to
appear uneven in thickness or color. Use the AlignVertexCenters
property to eliminate the uneven appearance.
Note
You must have a graphics card that supports this feature. To see if the feature is
supported, call the rendererinfo
function. If it is supported,
rendererinfo
returns value of 1
for
info.Details.SupportsAlignVertexCenters
.
Markers
Marker
— Marker symbol
"none"
(default) | "o"
| "+"
| "*"
| "."
| ...
Marker symbol, specified as one of the values listed in this table. By default, the object does not display markers. Specifying a marker symbol adds markers at each data point or vertex.
Marker | Description | Resulting Marker |
---|---|---|
"o" | Circle |
|
"+" | Plus sign |
|
"*" | Asterisk |
|
"." | Point |
|
"x" | Cross |
|
"_" | Horizontal line |
|
"|" | Vertical line |
|
"square" | Square |
|
"diamond" | Diamond |
|
"^" | Upward-pointing triangle |
|
"v" | Downward-pointing triangle |
|
">" | Right-pointing triangle |
|
"<" | Left-pointing triangle |
|
"pentagram" | Pentagram |
|
"hexagram" | Hexagram |
|
"none" | No markers | Not applicable |
MarkerMode
— Control how Marker
is set
"auto"
(default) | "manual"
Control how the Marker
property is set, specified as one of these values:
"auto"
— MATLAB controls the value of the object'sMarker
property by using theSeriesIndex
property of theLine
object and theLineStyleOrder
property of the axes."manual"
— You set the value of theMarker
property directly, or indirectly as a function argument when you create theLine
object.
If you change the value of the Marker
property manually,
MATLAB changes the value of the MarkerMode
property to
"manual"
.
MarkerIndices
— Indices of data points at which to display markers
1:length(YData)
(default) | vector of positive integers | scalar positive integer
Indices of data points at which to display markers, specified as a vector of positive integers. If you do not specify the indices, then MATLAB displays a marker at every data point.
Note
To see the markers, you must also specify a marker symbol.
Example: plot(x,y,"-o","MarkerIndices",[1 5 10])
displays a circle marker at
the first, fifth, and tenth data points.
Example: plot(x,y,"-x","MarkerIndices",1:3:length(y))
displays a cross
marker every three data points.
Example: plot(x,y,"Marker","square","MarkerIndices",5)
displays one square
marker at the fifth data point.
MarkerSize
— Marker size
6
(default) | positive value
Marker size, specified as a positive value in points, where 1 point = 1/72 of an inch.
MarkerEdgeColor
— Marker outline color
"auto"
(default) | RGB triplet | hexadecimal color code | "r"
| "g"
| "b"
| ...
Marker outline color, specified as "auto"
, an RGB triplet, a
hexadecimal color code, a color name, or a short name. The default value of
"auto"
uses the same color as the Color
property.
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" | |

MarkerFaceColor
— Marker fill color
"none"
(default) | "auto"
| RGB triplet | hexadecimal color code | "r"
| "g"
| "b"
| ...
Marker fill color, specified as "auto"
, an RGB triplet, a hexadecimal
color code, a color name, or a short name. The "auto"
option uses the
same color as the Color
property of the parent axes. If you specify
"auto"
and the axes plot box is invisible, the marker fill color is
the color of the figure.
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]

vector
Radius values, specified as a vector. ThetaData
and
RData
must be vectors of equal length.
This property applies only to lines in a polar axes.
ThetaData
— Angle values
vector
Angle values, specified as a vector. ThetaData
and
RData
must be vectors of equal length.
This property applies only to lines in a polar axes.
AffectAutoLimits
— Include data range in axes limits
"on"
(default) | on/off logical value
Since R2023a
Include the Line
object's data range in the automatic
selection of axes limits, specified as "on"
,
"off"
, logical 1
(true
), or
0
(false
). The value is stored as an on/off
logical value of type matlab.lang.OnOffSwitchState
.
By default, the axes limits automatically change to include the data range for each
successive line you create in the axes. Setting this property enables you to focus on
the range of a subset of lines. To exclude the data range of a line in the automatic
selection, set its AffectAutoLimits
property to
"off"
.
Both lines have AffectAutoLimits="on" | Thin red line has AffectAutoLimits="off" |
---|---|
|
|
Legend
DisplayName
— Legend label
''
(default) | character vector | string scalar
Legend label, specified as a character vector or string scalar. The legend does not
display until you call the legend
command. If you do not specify
the text, then legend
sets the label using the form
'dataN'
.
Annotation
— Include object in legend
Annotation
object
Include the object in the legend, specified as an Annotation
object. Set the underlying IconDisplayStyle
property of the
Annotation
object to one of these values:
"on"
— Include the object in the legend (default)."off"
— Do not include the object in the legend.
For example, to exclude the Line
object named
obj
from the legend, set the IconDisplayStyle
property to "off"
.
obj.Annotation.LegendInformation.IconDisplayStyle = "off";
Alternatively, you can control the items in a legend using the legend
function. Specify the first input argument as a vector of the
graphics objects to include. If you do not specify an existing graphics object in the
first input argument, then it does not appear in the legend. However, graphics objects
added to the axes after the legend is created do appear in the legend. Consider creating
the legend after creating all the plots to avoid extra items.
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.
DataTipTemplate
— Data tip content
DataTipTemplate
object
Data tip content, specified as a DataTipTemplate
object.
You can control the content that appears in a data tip by modifying the
properties of the underlying DataTipTemplate
object. For a
list of properties, see DataTipTemplate Properties.
For an example of modifying data tips, see Create Custom Data Tips.
This property applies only to lines with pinned data tips.
Note
The DataTipTemplate
object is not returned by
findobj
or findall
, and it
is not copied by copyobj
.
ContextMenu
— Context menu
empty GraphicsPlaceholder
array (default) | 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'
.
Clipping
— Clipping of object to axes limits
'on'
(default) | on/off logical value
Clipping of the object to the axes limits, 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
.
A value of
'on'
clips parts of the object that are outside the axes limits.A value of
'off'
displays the entire object, even if parts of it appear outside the axes limits. Parts of the object might appear outside the axes limits if you create a plot, sethold on
, freeze the axis scaling, and then create the object so that it is larger than the original plot.
The Clipping
property of the axes that contains the object must be set to
'on'
. Otherwise, this property has no effect. For more
information about the clipping behavior, see the Clipping
property of the
axes.
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
'on'
(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.
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:
If the value of
Interruptible
is'off'
, then no interruption occurs. Instead, theBusyAction
property of the object that owns the interrupting callback determines if the interrupting callback is discarded or added to the callback queue.If the value of
Interruptible
is'on'
, then the interruption occurs. The next time MATLAB processes the callback queue, it stops the execution of the running callback and executes the interrupting callback. After the interrupting callback completes, MATLAB then resumes executing the running callback.
Note
Callback interruption and execution behave differently in these situations:
If the interrupting callback is a
DeleteFcn
,CloseRequestFcn
, orSizeChangedFcn
callback, then the interruption occurs regardless of theInterruptible
property value.If the running callback is currently executing the
waitfor
function, then the interruption occurs regardless of theInterruptible
property value.If the interrupting callback is owned by a
Timer
object, then the callback executes according to schedule regardless of theInterruptible
property value.
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) | 'all'
| 'none'
Ability to capture mouse clicks, specified as one of these values:
'visible'
— Capture mouse clicks when visible. TheVisible
property must be set to'on'
and you must click a part of theLine
object that has a defined color. You cannot click a part that has an associated color property set to'none'
. If the plot contains markers, then the entire marker is clickable if either the edge or the fill has a defined color. TheHitTest
property determines if theLine
object responds to the click or if an ancestor does.'all'
— Capture mouse clicks regardless of visibility. TheVisible
property can be set to'on'
or'off'
and you can click a part of theLine
object that has no color. TheHitTest
property determines if theLine
object responds to the click or if an ancestor does.'none'
— Cannot capture mouse clicks. Clicking theLine
object passes the click through it to the object below it in the current view of the figure window. TheHitTest
property 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 theLine
object. If you have defined theContextMenu
property, then invoke the context menu.'off'
— Trigger the callbacks for the nearest ancestor of theLine
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 Line
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
Axes
object | PolarAxes
object | Group
object | Transform
object
Parent, specified as an Axes
, PolarAxes
, Group
, or Transform
object.
Children
— Children
empty GraphicsPlaceholder
array | DataTip
object array
Children, returned as an empty GraphicsPlaceholder
array or a
DataTip
object array. Use this property to view a list of data tips
that are plotted on the chart.
You cannot add or remove children using the Children
property. To add a
child to this list, set the Parent
property of the
DataTip
object to the chart object.
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
'line'
This property is read-only.
Type of graphics object, returned as 'line'
. 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 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 before R2006aR2023b: Control automatic color and line style selection with the SeriesIndex
property
Control how Line
objects vary in color, line style, and markers
by setting the SeriesIndex
property. This property is useful when you
want to match the colors, line styles, and markers of different objects in the axes.
R2023a: Control whether a line affects the automatic calculation of the axes limits with the AffectsAutoLimits
property
Specify whether a specific line affects the automatically selected axes limits by
setting the AffectsAutoLimits
property. By default, the axes
limits change to encompass the data range for each successive line you create.
Setting this property enables you to focus on the range of a subset of lines in the
axes.
R2020a: 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 Line
object.
