Each <code>hggroup</code> 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 original of the arrows. The properties of the quiver series are <dl> <dt><code>autoscale</code><dt><code>autoscalefactor</code><dd>Flag whether the length of the arrows is scaled or defined directly from the <var>u</var>, <var>v</var> and <var>w</var> data. If the arrow length is flagged as being scaled by the <code>autoscale</code> property, then the length of the autoscaled arrow is controlled by the <code>autoscalefactor</code>. <br><dt><code>maxheadsize</code><dd>This property controls the size of the head of the arrows in the quiver series. The default value is 0.2. <br><dt><code>showarrowhead</code><dd>Flag whether the arrow heads are displayed in the quiver plot. <br><dt><code>color</code><dd>The RGB color or color name of the line objects of the quiver. See <a href="Colors.html#Colors">Colors</a>. <br><dt><code>linewidth</code><dt><code>linestyle</code><dd>The line width and style of the line objects of the quiver. See <a href="Line-Styles.html#Line-Styles">Line Styles</a>. <br><dt><code>marker</code><dt><code>markerfacecolor</code><dt><code>markersize</code><dd>The line and fill color of the marker objects at the original of the arrows.
