I'm trying to draw any graph in NetworkX, but get nothing, not even errors:
import networkx as nx import matplotlib.pyplot as plt g1=nx.petersen_graph() nx.draw(g1)
Add to the end:
plt.show()
import networkx as nx import matplotlib.pyplot as plt g1 = nx.petersen_graph() nx.draw(g1) plt.show()
When run from an interactive shell where plt.ion() has been called, the plt.show() is not needed. This is probably why it is omitted in a lot of examples.
plt.ion()
If you run these commands from a script (where plt.ion() has not been called), the plt.show() is needed. plt.ion() is okay for interactive sessions, but is not recommended for scripts.
