+            Alter the way points are connected (by specifying a *scheme*) and
+            data are grouped (by specifying a *method*). Append one of three
+            line connection schemes:
+
+            - **c** : Draw continuous line segments for each group [Default].
+            - **r** : Draw line segments from a reference point reset for each
+              group.
+            - **n** : Draw networks of line segments between all points in
+              each group.
+
+            Optionally, append the one of four segmentation methods to define
+            the group:
+
+            - **a** : Ignore all segment headers, i.e., let all points belong
+              to a single group, and set group reference point to the very
+              first point of the first file.
+            - **f** : Consider all data in each file to be a single separate
+              group and reset the group reference point to the first point of
+              each group.
+            - **s** : Segment headers are honored so each segment is a group;
+              the group reference point is reset to the first point of each
+              incoming segment [Default].
+            - **r** : Same as **s**, but the group reference point is reset
+              after each record to the previous point (this method is only
+              available with the ``connection='r'`` scheme).
+
+            Instead of the codes **a**|**f**|**s**|**r** you may append the
+            coordinates of a *refpoint* which will serve as a fixed external
+            reference point for all groups.
         {G}
+        intensity : float or bool
+            Provide an *intens* value (nominally in the -1 to +1 range) to
+            modulate the fill color by simulating illumination [None]. If
+            using ``intensity=True``, we will instead read *intens* from the
