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. regards Jesper

Right. It was my fault, thank you. Anyway: Should'nt there be a more descriptive error message? And: It should definitly raise a PEAR_Error or Exception, so make this a feature request.

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 :)) regards Jesper

I just spent an hour with a similar problem. :/ I really love this package despite the missing error handling, would you like some support on moving to Pear_Error?
