+	  openarc   - Outline shape with curve and chord.
+	  chord     - Straight line chord between the ends of the curve,
+		      but without showing the curve.
+	  fillchord - Filled triangle between chord and center.
+	  openchord - Outline triangle between chord and center.
+	  pie       - Filled pie segment between curve and center.
