python不同颜色的边_如何在Python中使用igraph为不同的边指定不同的颜色？

我有一个有三种边的图：“company”、“std”和“res”。许多其他顶点没有边。在

当我绘制摘要时，我得到：IGRAPH UN-- 500 36 --

+ attr: area (v), cnpj (v), grande_area (v), name (v), res (v), std (v), company (e), res (e), std (e)

我想用不同的颜色绘制不同类型的边，但我找不到正确的代码。在

下面是我打印边缘时得到的示例：

^{pr2}$

我用来做边缘的代码是：def edge_group(g):

for v in g.vs:

for w in g.vs:

if v != w:

if g.are_connected(v, w) is False:

if v['name'].get_cnpj() != "":

if v["name"].get_cnpj() == w["name"].get_cnpj():

g.add_edge(v, w, company=True)

if len(set(v['std']).intersection(w['std'])) > 0:

g.add_edge(v, w, std=True)

if len(set(v['res']).intersection(w['res'])) > 0:

g.add_edge(v, w, res=True)

return g

这是给我所有边缘“黑色”的代码def drawing_group(g):

layout = g.layout("fr")

visual_style = {}

visual_style["vertex_size"] = 1

if g.es["company"] is True and g.es['res'] is True and g.es['std'] is True:

visual_style['edge_color'] = 'black'

if g.es["company"] is True and g.es['res'] is True:

visual_style['edge_color'] = 'grey'

if g.es["company"] is True and g.es['std'] is True:

visual_style['edge_color'] = 'green'

if g.es['company'] is True:

visual_style['edge_color'] = 'blue'

if g.es['res'] is True and g.es['std'] is True:

visual_style['edge_color'] = 'red'

if g.es['res'] is True:

visual_style['edge_color'] = 'yellow'

if g.es['std'] is True:

visual_style['edge_color'] = 'brown'

visual_style["layout"] = layout

visual_style["bbox"] = (500, 500)

visual_style["margin"] = 20

visual_style['hovermode'] = 'closest'

igraph.plot(g, 'output/gr_%s.png' % num, **visual_style)

提前谢谢。在
