kivy matplotlib test_backend.py and test_plt.py display error and exit error

[sem376]

Hello,
I'm using the following:
Windows 8 and Windows 10
IDE: Pycharm latest version
Python: version 3.4.4
Kivy: version 1.9.1
Matplotlib: version 1.5.3
Numpy: lastest version
Downloaded Matplotlib for kivy

When I test the test_backend.py code located here https://github.com/kivy-garden/garden.matplotlib/tree/master/examples, the code starts up, but the display isn't exactly how it suppose to look. Here attached is my display
, and these two locations show similar graphs (graphs like test_plt.py. test_plt.py give the same errors) : http://matplotlib.org/examples/api/barchart_demo.html and https://andnovar.wordpress.com/2015/06/11/backend-for-kivy-in-matplotlib-first-steps/

Also, when I close the graph window, I get this error message:

[INFO ] [Base ] Leaving application in progress...

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Finally, when I run test_backend.py, I get errors in this line:
from kivy.garden.matplotlib.backend_kivyagg import FigureCanvas,
NavigationToolbar2Kivy
which says there are unresolved references for backend_kivyagg, FigureCanvas, NavigationToolbar2Kivy

Does anyone understand why errors are occurring?

Thanks

Hi, I've a similar error

Very simple code

import matplotlib
matplotlib.use('module://kivy.garden.matplotlib.backend_kivy')
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(1,10,0.1)
y = x**2
fig = plt.figure()
ax, = plt.plot(x,y)
plt.show()

I attached the log
kivy_17-10-03_120.txt

Get the same issues with test_backend.py etc.

Any thoughts appreciated.
