[Matplotlib-users] At.: draw Graph problem

[Josè L. M. <jos...@ya...>]

Hi experts.
I have two problems:

1) plt.show() doesnt work:   When i draw simple plot doing


importnumpy asnp importmatplotlib.pyplot asplt
x =np.range(0,5,0.1);y =np.sin(x)plt.plot(x,y)
plt.show()

no picture appears.I try to do this: http://stackoverflow.com/questions/7534453/matplotlib-does-not-show-my-drawings-although-i-call-pyplot-show, but I cant save changes in the file matplotlibrc.

But, If I do:
importnumpy asnp importmatplotlib.pyplot asplt
x =np.range(0,5,0.1);y =np.sin(x)plt.plot(x,y)
plt.savefig('pppp.png')

the picture is generated and saved.2. When I try to draw a Graph (using NetworkX and Matplotlib) doing:

importnumpy asnp importmatplotlib.pyplot asplt
improt networkx as nx
x =nx.Graph(M) #M is my matrix
nx.draw(x)
plt.savefig('jjj.png')
I always get a pictule like the attached file. How can I restore my old-drawing style?

Waiting for your answer.

Thanks a lot!!
