I am sorry, you would need to use a more recent kivy version, some changes were made to **kwargs when instantiating a Widget that seems you don't have. Try to compile master from github and run the examples again.

Hi there,
I'm having trouble running the example code. I am using python 2.7, kivy 1.9.0, and matlab 1.4.3 on Ubuntu . I get a similar error when using python 3.4. I used the Kivy Garden tool to setup the garden.matplotlib add-on.
The following terminal dump is from running "test_backend.py". I get similar results when running the other two examples in the folder.
Terminal Dump:

Thanks in advance. I'm really excited that someone has provided matplotlib back end support for kivy. If I could get it to function, it would be an enormous help for my current project. Let me know if I can clarify anything. I will continue to see if I can find a solution.
