Problem with plotting a MultiDiGraph instance

[Saverio]

Hi all,

I have executed the following code:

import networkx as nx
import matplotlib.pyplot as plt

multidigraph= nx.MultiDiGraph()
multidigraph.add_nodes_from( [ '1','2','3','4' ] )
multidigraph.add_edges_from( [ ('1','2') ,  ('1','2') , ('2','1') , ('2','2') , ('1','3') ,
                               ('3','1') , ('2','4') , ( '3' , '4' ) ,  ( '4' , '3' ) , ( '4' , '2' ) ] )
plt.figure( 1 , figsize = ( 4 , 4 ) )
node_positions = { '1' : [ 0 , 1 ] , '2' : [ 1 , 1 ] , '3' : [ 0 , 0 ] , '4' : [ 1 , 0 ] }
nx.draw( multidigraph , pos = node_positions , with_labels = True , font_size = 15 , node_size = 400, edge_color = 'blue', arrowsize = 30 )
plt.show()

In the plot are not present all the edges.

To be  more precise in the plot one edge represents more egdes in the edge list.

Where I'm wrong?

Any suggestions to plot all the edges?

Thanks.

Hi Saverio,

I'd like to double up on this actually. This has been happening to me too. 

Any hints on how to solve this issue would be useful. 

Thanks in advance.

Best wishes,

Borjan
