#### 15.3.3.4 Line Properties

The `line` properties are:

`__modified__`: `"off"` | {`"on"`}
`beingdeleted`: {`"off"`} | `"on"`
`busyaction`: `"cancel"` | {`"queue"`}
`buttondownfcn`: string | function handle, def. `[](0x0)`
`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. See 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 (0, "defaultlinecreatefcn", 'disp ("line created!")')` .

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

  Callback function executed immediately before line is deleted.

`displayname`: string | cell array of strings, def. `""`

  Text for the legend entry corresponding to this line.

`erasemode`: `"background"` | `"none"` | {`"normal"`} | `"xor"`

  `erasemode` is unused.

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

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

`hittest`: `"off"` | {`"on"`}
`interpreter`: `"latex"` | `"none"` | {`"tex"`}
`interruptible`: `"off"` | {`"on"`}
`linestyle`: {`"-"`} | `"--"` | `"-."` | `":"` | `"none"`

  See 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. See 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. See 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. See colorspec.

`markersize`: scalar, def. `6`

  Size of the markers measured in points.

`parent`: graphics handle

  Handle of the parent graphics object.

`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`: def. `[](0x0)`
`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.
