#### 15.4.6.7 Quiver Group

Quiver series objects are created by the `quiver` or `quiver3` functions. Each `hggroup` element of the series contains three line objects as children representing the body and head of the arrow, together with a marker as the point of origin of the arrows. The properties of the quiver series are

`autoscale`
`autoscalefactor`

  Flag whether the length of the arrows is scaled or defined directly from the u, v and w data. If the arrow length is flagged as being scaled by the `autoscale` property, then the length of the autoscaled arrow is controlled by the `autoscalefactor`.

`maxheadsize`

  This property controls the size of the head of the arrows in the quiver series. The default value is 0.2.

`showarrowhead`

  Flag whether the arrow heads are displayed in the quiver plot.

`color`

  The RGB color or color name of the line objects of the quiver. See Colors.

`linewidth`
`linestyle`

  The line width and style of the line objects of the quiver. See Line Styles.

`marker`
`markerfacecolor`
`markersize`

  The line and fill color of the marker objects at the original of the arrows. See Colors.

`xdata`
`ydata`
`zdata`

  The origins of the values of the vector field.

`udata`
`vdata`
`wdata`

  The values of the vector field to plot.

`xdatasource`
`ydatasource`
`zdatasource`
`udatasource`
`vdatasource`
`wdatasource`

  Data source variables.
