The figure properties are:

__modified__: "off" | {"on"}

createfcn: string | function handle, def. [](0x0)

currentaxes: graphics handle, def. [](0x0)

Handle to the graphics object of the current axes.

currentcharacter (read-only): def. ""

currentcharacter is unused.

currentobject (read-only): graphics handle, def. [](0x0)
currentpoint (read-only): two-element vector, def. [0; 0]

A 1-by-2 matrix which holds the coordinates of the point over which the mouse pointer was when a mouse event occurred. The X and Y coordinates are in units defined by the figure’s units property and their origin is the lower left corner of the plotting area.

Events which set currentpoint are

A mouse button was pressed


A mouse button was released

only if the figure’s callback windowbuttonupfcn is defined

The pointer was moved while pressing the mouse button (drag)

only if the figure’s callback windowbuttonmotionfcn is defined

deletefcn: string | function handle, def. [](0x0)

Callback function executed immediately before figure is deleted.

dockcontrols: {"off"} | "on"

dockcontrols is unused.

filename: string, def. ""

The filename used when saving the plot figure.

graphicssmoothing: "off" | {"on"}

Use smoothing techniques to reduce the appearance of jagged lines.

handlevisibility: "callback" | "off" | {"on"}

If handlevisibility is "off", the figure’s handle is not visible in its parent’s "children" property.

hittest: "off" | {"on"}
integerhandle: "off" | {"on"}

Assign the next lowest unused integer as the Figure number.

interruptible: "off" | {"on"}
inverthardcopy: "off" | {"on"}

Replace the figure and axes background color with white when printing.

keypressfcn: string | function handle, def. [](0x0)
keyreleasefcn: string | function handle, def. [](0x0)

With keypressfcn, the keyboard callback functions. These callback functions are called when a key is pressed/released respectively. The functions are called with two input arguments. The first argument holds the handle of the calling figure. The second argument holds an event structure which has the following members:


The ASCII value of the key


Lowercase value of the key


A cell array containing strings representing the modifiers pressed with the key.

menubar: {"figure"} | "none"

Control the display of the figure menu bar in the upper left of the figure.

name: string, def. ""

Name to be displayed in the figure title bar. The name is displayed to the right of any title determined by the numbertitle property.

nextplot: {"add"} | "new" | "replace" | "replacechildren"
numbertitle: "off" | {"on"}

Display "Figure" followed by the numerical figure handle value in the figure title bar.

outerposition: four-element vector, def. [-1 -1 -1 -1]
paperorientation: "landscape" | {"portrait"}

The value for the papersize, and paperposition properties depends upon paperorientation. The horizontal and vertical values for papersize and paperposition reverse order when paperorientation is switched between "portrait" and "landscape".

paperposition: four-element vector, def. [0.25000 2.50000 8.00000 6.00000]

Vector [left bottom width height] defining the position and size of the figure (in paperunits units) on the printed page. The position [left bottom] defines the lower left corner of the figure on the page, and the size is defined by [width height]. For output formats not implicitly rendered on paper, width and height define the size of the image and the position information is ignored. Setting paperposition also forces the paperpositionmode property to be set to "manual".

paperpositionmode: "auto" | {"manual"}

If paperpositionmode is set to "auto", the paperposition property is automatically computed: the printed figure will have the same size as the on-screen figure and will be centered on the output page. Setting the paperpositionmode to "auto" does not modify the value of the paperposition property.

papersize: two-element vector, def. [8.5000 11.0000]

Vector [width height] defining the size of the paper for printing. Setting the papersize property to a value, not associated with one of the defined papertypes and consistent with the setting for paperorientation, forces the papertype property to the value "<custom>". If papersize is set to a value associated with a supported papertype and consistent with the paperorientation, the papertype value is modified to the associated value.

papertype: "<custom>" | "a" | "a0" | "a1" | "a2" | "a3" | "a4" | "a5" | "arch-a" | "arch-b" | "arch-c" | "arch-d" | "arch-e" | "b" | "b0" | "b1" | "b2" | "b3" | "b4" | "b5" | "c" | "d" | "e" | "tabloid" | "uslegal" | {"usletter"}

Name of the paper used for printed output. Setting papertype also changes papersize, while maintaining consistency with the paperorientation property.

paperunits: "centimeters" | {"inches"} | "normalized" | "points"

The unit used to compute the paperposition property. For paperunits set to "pixels", the conversion between physical units (ex: "inches") and "pixels" is dependent on the screenpixelsperinch property of the root object.

parent: graphics handle, def. 0

Handle of the parent graphics object.

pointer: {"arrow"} | "botl" | "botr" | "bottom" | "circle" | "cross" | "crosshair" | "custom" | "fleur" | "fullcrosshair" | "hand" | "ibeam" | "left" | "right" | "top" | "topl" | "topr" | "watch"

pointer is unused.

pointershapecdata: def. 16-by-16 double

pointershapecdata is unused.

pointershapehotspot: def. [0 0]

pointershapehotspot is unused.

position: four-element vector, def. [300 200 560 420]

Specify the position and size of the figure. The four elements of the vector are the coordinates of the lower left corner and width and height of the figure. See units property.

renderer: {"opengl"} | "painters"
renderermode: {"auto"} | "manual"
resize: "off" | {"on"}

resize is unused.

resizefcn: string | function handle, def. [](0x0)

resizefcn is deprecated. Use sizechangedfcn instead.

selected: {"off"} | "on"
selectionhighlight: "off" | {"on"}
selectiontype: "alt" | "extend" | {"normal"} | "open"
sizechangedfcn: string | function handle, def. [](0x0)

Callback triggered when the figure window size is changed.

tag: string, def. ""

A user-defined string to label the graphics object.

toolbar: {"auto"} | "figure" | "none"

Control the display of the toolbar along the bottom of the figure window. When set to "auto", the display is based on the value of the menubar property.

type (read-only): string

Class name of the graphics object. type is always "figure"

uicontextmenu: graphics handle, def. [](0x0)

Graphics handle of the uicontextmenu object that is currently associated to this figure object.

units: "centimeters" | "characters" | "inches" | "normalized" | {"pixels"} | "points"

The unit used to compute the position and outerposition properties.

userdata: Any Octave data, def. [](0x0)

User-defined data to associate with the graphics object.

visible: "off" | {"on"}

If visible is "off", the figure is not rendered on screen.

windowbuttondownfcn: string | function handle, def. [](0x0)

See windowbuttonupfcn property.

windowbuttonmotionfcn: string | function handle, def. [](0x0)

See windowbuttonupfcn property.

windowbuttonupfcn: string | function handle, def. [](0x0)

With windowbuttondownfcn and windowbuttonmotionfcn, the mouse callback functions. These callback functions are called when a mouse button is pressed, dragged, or released respectively. When these callback functions are executed, the currentpoint property holds the current coordinates of the cursor.

windowkeypressfcn: string | function handle, def. [](0x0)
windowkeyreleasefcn: string | function handle, def. [](0x0)
windowscrollwheelfcn: string | function handle, def. [](0x0)
windowstyle: "docked" | "modal" | {"normal"}

The window style of a figure. One of the following values:


Set the window style as non modal.


Set the window as modal so that it will stay on top of all normal figures.


Setting the window style as docked currently does not dock the window.

Changing modes of a visible figure may cause the figure to close and reopen.
