Opensuse42 python matplotlib paint does not show __python

Python under the drawing, but did not draw out, because the Matplotlib display mode is agg, Tkagg can be installed matplotlib

sudo zypper install matplotlib

example of a problem:

>>> import Matplotlib.pyplot as plt
>>> x = [1,2,3,4,5]
>>> y = [1,4,9,16,25]
>>> Plt.plot (x,y)
>>> plt.show ()

But there is no map to make, there is no error, out[4]: [

>>> from Matplotlib.pyplot import savefig
>>> savefig (' save.png ')

I got the graph I wanted in the current directory, which means matplotlib is fine, but MATPLOTLIB-TK does not invoke and display the solution:

To view the location of the backend configuration file:

Matplotlib.matplotlib_fname ()

My computer is on the path
/usr/lib64/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc

To open a configuration file:

sudo vi/usr/lib64/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc

Approximately 38 lines in the position are:

Backend      : Agg

Change it to read:

Backend      : Tkagg

can be displayed
