This a bug in your graph :)
The factory method takes as second parameter an array of parameters to pass to the constructor of the object. This means that you should simply change your code from:
$graph = Image_Graph::factory('graph', 300, 100);
to
$graph = Image_Graph::factory('graph', array(300, 100));
And you should get the expected result.

Well I guess that's a good idea - you know it's just one of these things that are at the end of the list (and seem to stay there :))
