15.3.3.4 Line Properties
........................

The ‘line’ properties are:

‘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").  Note:
     Callbacks section.

‘buttondownfcn’: string | function handle, def. ‘[](0x0)’
     For information on how to write graphics listener functions see
     Note: Callbacks section.

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

‘clipping’: "off" | {"on"}
     If ‘clipping’ is "on", the line is clipped in its parent axes
     limits.

‘color’: colorspec, def. ‘[0 0 0]’
     Color of the line object.  Note: colorspec.

‘createfcn’: string | function handle, def. ‘[](0x0)’
     Callback function executed immediately after line has been created.
     Function is set by using default property on root object, e.g.,
     ‘set (groot, "defaultlinecreatefcn", 'disp ("line created!")')’.

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

‘deletefcn’: string | function handle, def. ‘[](0x0)’
     Callback function executed immediately before line is deleted.

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

‘displayname’: string | cell array of strings, def. ""
     Text for the legend entry corresponding to this line.

‘handlevisibility’: "callback" | "off" | {"on"}
     If ‘handlevisibility’ is "off", the line’s handle is not visible in
     its parent’s "children" property.

‘hittest’: "off" | {"on"}
     Specify whether line 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.  Note:
     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.  Note:
     Callbacks section.

‘linejoin’: "chamfer" | "miter" | {"round"}
     Control the shape of the junction of line segments.  This property
     currently only affects the printed output.

‘linestyle’: {"-"} | "–" | "-." | ":" | "none"
     Note: Line Styles.

‘linewidth’: def. ‘0.50000’
     Width of the line object measured in points.

‘marker’: "*" | "+" | "." | "<" | ">" | "^" | "d" | "diamond" | "h" | "hexagram" | {"none"} | "o" | "p" | "pentagram" | "s" | "square" | "v" | "x"
     Shape of the marker for each data point.  Note: Marker Styles.

‘markeredgecolor’: {"auto"} | "none"
     Color of the edge of the markers.  When set to "auto", the marker
     edges have the same color as the line.  If set to "none", no marker
     edges are displayed.  This property can also be set to any color.
     Note: colorspec.

‘markerfacecolor’: "auto" | {"none"}
     Color of the face of the markers.  When set to "auto", the marker
     faces have the same color as the line.  If set to "none", the
     marker faces are not displayed.  This property can also be set to
     any color.  Note: colorspec.

‘markersize’: scalar, def. ‘6’
     Size of the markers measured in points.

‘parent’: graphics handle
     Handle of the parent graphics object.

‘pickableparts’: "all" | "none" | {"visible"}
     Specify whether line will accept mouse clicks.  By default,
     ‘pickableparts’ is "visible" and only visible parts of the line 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.  Note:
     hittest property.

‘selected’: {"off"} | "on"

‘selectionhighlight’: "off" | {"on"}

‘tag’: string, def. ""
     A user-defined string to label the graphics object.

‘type’ (read-only): string
     Class name of the graphics object.  ‘type’ is always "line"

‘uicontextmenu’: graphics handle, def. ‘[](0x0)’
     Graphics handle of the uicontextmenu object that is currently
     associated to this line object.

‘userdata’: Any Octave data, def. ‘[](0x0)’
     User-defined data to associate with the graphics object.

‘visible’: "off" | {"on"}
     If ‘visible’ is "off", the line is not rendered on screen.

‘xdata’: vector, def. ‘[0 1]’
     Vector of x data to be plotted.

‘xdatasource’: string, def. ""
     Name of a vector in the current base workspace to use as x data.

‘ydata’: vector, def. ‘[0 1]’
     Vector of y data to be plotted.

‘ydatasource’: string, def. ""
     Name of a vector in the current base workspace to use as y data.

‘zdata’: vector, def. ‘[](0x0)’
     Vector of z data to be plotted.

‘zdatasource’: string, def. ""
     Name of a vector in the current base workspace to use as z data.
