garden.matplotlib: AttributeError: 'FigureCanvasAgg' object has no attribute 'bind'

[David Aldrich]

Hi

I'm running Kivy Master with latest garden.matplotlib on Windows 8.1.

If I call:

plt.tight_layout()

I get exception:

 C:\Kivy-1.9.0-py3.4-win32-x64\Python34\lib\site-packages\matplotlib\tight_layout.py:225: UserWarning: tight_layout : falling back to Agg renderer

Fixed.  I was calling tight_layout before adding the canvas widget.  This order works ok:

        self.add_widget(canvas)

        self.fig.tight_layout()

        plt.show()
