+=head2 Legend
+
+[B<-g>|B<--no-legend>]
+
+Suppress generation of the legend; only render the graph.
+
+[B<-F>|B<--force-rules-legend>]
+
+Force the generation of HRULE and VRULE legends even if those HRULE or
+VRULE will not be drawn because out of graph boundaries (mimics
+behaviour of pre 1.0.42 versions).
+
+[B<--legend-position>=(north|south|west|east)]
+
+Place the legend at the given side of the graph. The default is south.
+In west or east position it is necessary to add line breaks manually.
+
+[B<--legend-direction>=(topdown|bottomup)]
+
+Place the legend items in the given vertical order. The default is topdown.
+Using bottomup the legend items appear in the same vertical order as a
+stack of lines or areas.
+
=head2 Miscellaneous
