Properties of patch objects (see patch):
alphadatamapping: "direct" | "none" | {"scaled"}Transparency is not yet implemented for patch objects. alphadatamapping is unused.
ambientstrength: scalar, def. 0.3000Strength of the ambient light. Value between 0.0 and 1.0
backfacelighting: "lit" | {"reverselit"} | "unlit""lit": The normals are used as is for lighting. "reverselit": The normals are always oriented towards the point of view. "unlit": Faces with normals pointing away from the point of view are unlit.
beingdeleted: {"off"} | "on"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.
cdata: scalar | matrix, def. [](0x0)Data defining the patch object color. Patch color can be defined for faces or for vertices.
If cdata is a scalar index into the current colormap or a RGB triplet, it defines the color of all faces.
If cdata is an N-by-1 vector of indices or an N-by-3 (RGB) matrix, it defines the color of each one of the N faces.
If cdata is an N-by-M or an N-by-M-by-3 (RGB) matrix, it defines the color at each vertex.
cdatamapping: "direct" | {"scaled"}children (read-only): vector of graphics handles, def. [](0x1)children is unused.
clipping: "off" | {"on"}If clipping is "on", the patch is clipped in its parent axes limits.
contextmenu: graphics handle, def. [](0x0)Graphics handle of the uicontextmenu object that is currently associated to this patch object.
createfcn: string | function handle, def. [](0x0)Callback function executed immediately after patch has been created. Function is set by using default property on root object, e.g., set (groot, "defaultpatchcreatefcn", 'disp ("patch created!")').
For information on how to write graphics listener functions see Callbacks section.
deletefcn: string | function handle, def. [](0x0)Callback function executed immediately before patch is deleted.
For information on how to write graphics listener functions see Callbacks section.
diffusestrength: scalar, def. 0.6000Strength of the diffuse reflex. Value between 0.0 (no diffuse reflex) and 1.0 (full diffuse reflex).
displayname: def. ""Text of the legend entry corresponding to this patch.
edgealpha: scalar | matrix, def. 1Transparency is not yet implemented for patch objects. edgealpha is unused.
edgecolor: def. [0 0 0]edgelighting: "flat" | "gouraud" | {"none"} | "phong"When set to a value other than "none", the edges of the object are drawn with light and shadow effects. Supported values are "none" (no lighting effects), "flat" (facetted look) and "gouraud" (linear interpolation of the lighting effects between the vertices). "phong" is deprecated and has the same effect as "gouraud".
facealpha: scalar | "flat" | "interp", def. 1Transparency level of the faces of the patch object. Only double values are supported at present where a value of 0 means complete transparency and a value of 1 means solid faces without transparency. Setting the property to "flat" or "interp" causes the faces to not being rendered. Additionally, the faces are not sorted from back to front which might lead to unexpected results when rendering layered transparent faces.
facecolor: {colorspec} | "none" | "flat" | "interp", def. [0 0 0]facelighting: {"flat"} | "gouraud" | "none" | "phong"When set to a value other than "none", the faces of the object are drawn with light and shadow effects. Supported values are "none" (no lighting effects), "flat" (facetted look) and "gouraud" (linear interpolation of the lighting effects between the vertices). "phong" is deprecated and has the same effect as "gouraud".
facenormals: def. [](0x0)Face normals are used for lighting the edges or faces if the edgelighting or facelighting properties are set to "flat". Setting facenormals also forces the facenormalsmode property to be set to "manual"
facenormalsmode: {"auto"} | "manual"If this property is set to "auto", facenormals are automatically calculated if the edgelighting or facelighting property are set to "flat" and at least one light object is present and visible in the same axes.
faces: vector | matrix, def. [1 2 3]facevertexalphadata: scalar | matrix, def. [](0x0)Transparency is not yet implemented for patch objects. facevertexalphadata is unused.
facevertexcdata: def. [](0x0)handlevisibility: "callback" | "off" | {"on"}If handlevisibility is "off", the patch’s handle is not visible in its parent’s "children" property.
hittest: "off" | {"on"}Specify whether patch 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.
linestyle: {"-"} | "--" | "-." | ":" | "none"linewidth: def. 0.5000marker: "*" | "+" | "." | "<" | ">" | "^" | "_" | "d" | "diamond" | "h" | "hexagram" | {"none"} | "o" | "p" | "pentagram" | "s" | "square" | "v" | "x" | "|"See line marker property.
markeredgecolor: {"auto"} | "flat" | "none"See line markeredgecolor property.
markerfacecolor: "auto" | "flat" | {"none"}See line markerfacecolor property.
markersize: scalar, def. 6parent: graphics handleHandle of the parent graphics object.
pickableparts: "all" | "none" | {"visible"}Specify whether patch will accept mouse clicks. By default, pickableparts is "visible" and only visible parts of the patch 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.
selected: {"off"} | "on"selectionhighlight: "off" | {"on"}specularcolorreflectance: scalar, def. 1Reflectance for specular color. Value between 0.0 (color of underlying face) and 1.0 (color of light source).
specularexponent: scalar, def. 10Exponent for the specular reflex. The lower the value, the more the reflex is spread out.
specularstrength: scalar, def. 0.9000Strength of the specular reflex. Value between 0.0 (no specular reflex) and 1.0 (full specular reflex).
tag: string, def. ""A user-defined string to label the graphics object.
type (read-only): stringClass name of the graphics object. type is always "patch"
userdata: Any Octave data, def. [](0x0)User-defined data to associate with the graphics object.
vertexnormals: def. [](0x0)Vertex normals are used for lighting the edges or faces if the edgelighting or facelighting properties are set to "gouraud". Setting vertexnormals also forces the vertexnormalsmode property to be set to "manual"
vertexnormalsmode: {"auto"} | "manual"If this property is set to "auto", vertexnormals are automatically calculated if the edgelighting or facelighting property are set to "gouraud" and at least one light object is present and visible in the same axes.
vertices: vector | matrix, def. 3-by-2 doublevisible: "off" | {"on"}If visible is "off", the patch is not rendered on screen.
xdata: vector | matrix, def. [0; 1; 0]ydata: vector | matrix, def. [1; 1; 0]zdata: vector | matrix, def. [](0x0)
