The following simple directed graph has truncated arrowheads:
vpos = {'W':(-0.5,0.5),'E':(0.5,0.5),'mW':(-0.5,0),'mE':(0.5,0)}
D1 = DiGraph()
D1.add_edge(('mW','mE','mE-mW'))
D1.add_edge(('W','E','W-E'))
D1.add_edge(('mW','W'))
D1.show(pos=vpos,vertex_size=500,figsize=(2,2))
If I change the last statement to:
D1.show(pos=vpos)
I still get truncated horizontal arrows, but less on the vertical.
Any suggestions for preserving full arrowheads? It looks like the clip limits for arrows are different than those for vertices. Setting fig_tight=False has no effect.
