+ *
+ * This class also handles coordinates and the correct managment of setting the

+ *
+ * $Graph =& Image_Graph::factory('graph', array(array('width' => 400,
+ * 'height' => 300, 'canvas' => 'jpg')));
+ *
+ * NB! In thïs case remember the "double" array (see {@link Image_Graph::
+ * factory()})
+ *
+ * 2) Use the canvas specified, pass a valid Image_Canvas as
+ * parameter. Remember to pass by reference, i. e. &amp;$canvas, fx.:
+ *
+ * $Graph =& new Image_Graph($Canvas);
+ *
+ * or using the factory method:

+ * $Graph =& Image_Graph::factory('graph', $Canvas));
