After
D = Poset(( divisors(12), attrcall("divides") ))
mb={x:D.mobius_function(x, D.top()) for x in D}
labels={x:(x, mb[x]) for x in D}
v_colors={"red": [e for e in D if mb[e]>0], "gray": [e for e in D if mb[e]==0],
"blue": [e for e in D if mb[e]<0]}
it seems that
D.plot(element_labels=labels)
and
D.plot(vertex_colors=v_colors, vertex_shape="s", vertex_size=2000, figsize=6)
works, but
D.plot(element_labels=labels, vertex_colors=v_colors, vertex_shape="s",
vertex_size=2000, figsize=6)
says
Traceback (click to the left of this block for traceback)
...
KeyError: 4
Why so?
