ImplicitFunctionLine Properties

Implicit line chart appearance and behavior

ImplicitFunctionLine properties control the appearance and behavior of an ImplicitFunctionLine object. By changing property values, you can modify certain aspects of the line chart. You can use dot notation to refer to a particular object and property:

fp = fimplicit(@(x,y) x.^2 + y.^2 - 3)
lw = fp.LineWidth
fp.LineWidth = 2

Color and Styling

expand all

Line color, 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.

Marker size, specified as a positive value in points, where 1 point = 1/72 of an inch.

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].

Marker fill color, specified as 'auto', an RGB triplet, a hexadecimal color code, a color name, or a short name. The 'auto' value uses the same color as the MarkerEdgeColor 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].

Function

expand all

Function to plot, specified as a function handle, anonymous function, or a symbolic expression or function.

Plotting interval for x values, specified as a two-element vector of the form [xmin xmax].

Selection mode for XRange, specified as one of these values:

  • 'auto' — Use the default value [-5 5]. If axes limits are specified, follow the specified limits instead.

  • 'manual' — Use manually specified values. To specify the values, set the XRange property.

Plotting interval for y values, specified as a two-element vector of the form [ymin ymax].

Selection mode for YRange, specified as one of these values:

  • 'auto' — Use the default value [-5 5]. If the axes limits are specified, follow the specified limits instead.

  • 'manual' — Use manually specified values. To specify the values, set the YRange property.

Number of evaluation points, specified as a scalar.

Data

expand all

This property is read-only.

x values, returned as a vector. XData, YData, and ZData have equal lengths.

This property is read-only.

y values, returned as a vector. XData, YData, and ZData have equal lengths.

This property is read-only.

z values, returned as a vector of zeros. XData, YData, and ZData have equal lengths.

Legend

expand all

Text for legend label, specified as a custom character vector or string. The default label is autogenerated from the Function property and the texlabel function. The legend does not appear until you call the legend function.

Data Types: char | string

This property is read-only.

Control for including or excluding the object from a legend, returned as an Annotation object. Set the underlying IconDisplayStyle property 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 a graphics object, go, from the legend set the IconDisplayStyle property to 'off'.

go.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

expand all

State of visibility, specified as one of these values:

  • '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 one of these values:

  • '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 one of these values:

  • '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'.

Clipping of the object to the axes limits, specified as one of these values:

  • 'on' — Do not display parts of the object that are outside the axes limits.

  • 'off' — Display 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, set hold 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

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 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.

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 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.

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 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.

Callback Execution Control

expand all

Callback interruption, specified as 'on' or 'off'. The Interruptible 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. The Interruptible property has two possible values:

  • '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.

  • '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.

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.

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 ImplicitFunctionLine 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. The HitTest property determines if the ImplicitFunctionLine 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' and you can click a part of the ImplicitFunctionLine object that has no color. The HitTest property determines if the ImplicitFunctionLine object responds to the click or if an ancestor does.

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

Response to captured mouse clicks, specified as one of these values:

  • 'on' — Trigger the ButtonDownFcn callback of the ImplicitFunctionLine object. If you have defined the UIContextMenu property, then invoke the context menu.

  • 'off' — Trigger the callbacks for the nearest ancestor of the ImplicitFunctionLine 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 ImplicitFunctionLine object can capture mouse clicks. If it cannot, then the HitTest property has no effect.

This property is read-only.

Deletion status, returned as 'off' or 'on'. 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, specified as an Axes, Group, or Transform object.

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 to the UI 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.

Identifiers

expand all

This property is read-only.

Type of graphics object, returned as 'implicitfunctionline'. Use this property to find all objects of a given type within a plotting hierarchy, for example, searching for the type using findobj.

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.
