15.3.3.3 Axes Properties

Properties of axes objects (see axes):

activepositionproperty: {"outerposition"} | "position"

Specify which of "position" or "outerposition" properties takes precedence when axes annotations extent changes. See position property, and outerposition property.

alim: def. [0 1]

Transparency is not yet implemented for axes objects. alim is unused.

alimmode: {"auto"} | "manual"

ambientlightcolor: def. [1 1 1]

ambientlightcolor is unused.

beingdeleted: {"off"} | "on"

box: {"off"} | "on"

Control whether the axes has a surrounding box.

boxstyle: {"back"} | "full"

For 3-D axes, control whether the "full" box is drawn or only the 3 "back" axes

busyaction: "cancel" | {"queue"}

Define how Octave handles the execution of this object’s callback properties when it is unable to interrupt another object’s executing callback. This is only relevant when the currently executing callback object has its interruptible property set to "off". The busyaction property of the interrupting callback object indicates whether the interrupting callback is queued ("queue" (default)) or discarded ("cancel"). See Callbacks section.

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

For information on how to write graphics listener functions see Callbacks section.

cameraposition: three-element vector, def. [0.5000 0.5000 9.1603]

camerapositionmode: {"auto"} | "manual"

cameratarget: three-element vector, def. [0.5000 0.5000 0.5000]

cameratargetmode: {"auto"} | "manual"

cameraupvector: three-element vector, def. [0 1 0]

cameraupvectormode: {"auto"} | "manual"

cameraviewangle: scalar, def. 6.6086

cameraviewanglemode: {"auto"} | "manual"

children (read-only): vector of graphics handles, def. [](0x1)

Graphics handles of the axes’s children.

clim: two-element vector, def. [0 1]

Define the limits for the color axis of image children. Setting clim also forces the climmode property to be set to "manual". See pcolor function.

climmode: {"auto"} | "manual"

clipping: "off" | {"on"}

clipping is unused.

clippingstyle: {"3dbox"} | "rectangle"

clippingstyle is unused.

color: colorspec, def. [1 1 1]

Color of the axes background. See colorspec.

colormap: def. 64-by-3 double

colororder: N-by-3 RGB matrix, def. 7-by-3 double

RGB values used by plot function for automatic line coloring.

colororderindex: def. 1

colororderindex is unused.

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

Callback function executed immediately after axes has been created. Function is set by using default property on root object, e.g., set (groot, "defaultaxescreatefcn", 'disp ("axes created!")').

For information on how to write graphics listener functions see Callbacks section.

currentpoint: 2-by-3 matrix, def. 2-by-3 double

Matrix [xf, yf, zf; xb, yb, zb] which holds the coordinates (in axes data units) of the point over which the mouse pointer was when the mouse button was pressed. If a mouse callback function is defined, currentpoint holds the pointer coordinates at the time the mouse button was pressed. For 3-D plots, the first row of the returned matrix specifies the point nearest to the current camera position and the second row the furthest point. The two points forms a line which is perpendicular to the screen.

dataaspectratio: three-element vector, def. [1 1 1]

Specify the relative height and width of the data displayed in the axes. Setting dataaspectratio to [1, 2] causes the length of one unit as displayed on the x-axis to be the same as the length of 2 units on the y-axis. See daspect function. Setting dataaspectratio also forces the dataaspectratiomode property to be set to "manual".

dataaspectratiomode: {"auto"} | "manual"

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

Callback function executed immediately before axes is deleted.

For information on how to write graphics listener functions see Callbacks section.

fontangle: "italic" | {"normal"}

Control whether the font is italic or normal.

fontname: string, def. "*"

Name of font used for text rendering. When setting this property, the text rendering engine will search for a matching font in your system. If none is found then text is rendered using a default sans serif font (same as the default "*" value).

Programming Note: On systems that don’t use FontConfig natively (all but Linux), the font cache is built when Octave is installed. You will need to run system ("fc-cache -fv") manually after installing new fonts.

fontsize: scalar, def. 10

Size of the font used for text rendering. See fontunits property.

fontsmoothing: "off" | {"on"}

Control whether any text associated with axes is anti-aliased.

fontunits: "centimeters" | "inches" | "normalized" | "pixels" | {"points"}

Units used to interpret the "fontsize" property.

fontweight: "bold" | {"normal"}

Control the variant of the base font used for text rendering.

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

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

hittest: "off" | {"on"}

Specify whether axes processes mouse events or passes them to ancestors of the object. When enabled, the object may respond to mouse clicks by evaluating the "buttondownfcn", showing the uicontextmenu, and eventually becoming the root "currentobject". This property is only relevant when the object can accept mouse clicks which is determined by the "pickableparts" property. See pickableparts property.

interruptible: "off" | {"on"}

Specify whether this object’s callback functions may be interrupted by other callbacks. By default interruptible is "on" and callbacks that make use of drawnow, figure, waitfor, getframe or pause functions are eventually interrupted. See Callbacks section.

Ratio between the x/y/zlabel fontsize and the tick label fontsize

layer: {"bottom"} | "top"

Fraction of axes limits to zoom for each wheel movement.

nextplot: "add" | {"replace"} | "replacechildren"

nextplot is used by high level plotting functions to decide what to do with graphics objects already present in the axes. See newplot function. The state of nextplot is typically controlled using the hold function. See hold function.

outerposition: four-element vector, def. [0 0 1 1]

Specify the position of the plot including titles, axes, and legend. The four elements of the vector are the coordinates of the lower left corner and width and height of the plot, in units normalized to the width and height of the plot window. For example, [0.2, 0.3, 0.4, 0.5] sets the lower left corner of the axes at (0.2, 0.3) and the width and height to be 0.4 and 0.5 respectively. See position property.

parent: graphics handle

Handle of the parent graphics object.

pickableparts: "all" | "none" | {"visible"}

Specify whether axes will accept mouse clicks. By default, pickableparts is "visible" and only visible parts of the axes or its children may react to mouse clicks. When pickableparts is "all" both visible and invisible parts (or children) may react to mouse clicks. When pickableparts is "none" mouse clicks on the object are ignored and transmitted to any objects underneath this one. When an object is configured to accept mouse clicks the "hittest" property will determine how they are processed. See hittest property.

position: four-element vector, def. [0.1300 0.1100 0.7750 0.8150]

Specify the position of the plot excluding titles, axes, and legend. The four elements of the vector are the coordinates of the lower left corner and width and height of the plot, in units normalized to the width and height of the plot window. For example, [0.2, 0.3, 0.4, 0.5] sets the lower left corner of the axes at (0.2, 0.3) and the width and height to be 0.4 and 0.5 respectively. See outerposition property.
