问题描述
我想按颜色和相同的间距对节点进行聚类。下图是我想要实现的目标:
以下是我目前拥有的:
如您所见,节点簇不像第一张图片那样形成半圆。有没有办法对集群进行排序以实现与第一张图像相同的视觉效果?
我用来集群节点的代码是:
# dictionary that associates each node to a HEX code color (the dictionary is longer in the image I generated,but to give an idea I omitted some)
nodesWithGroup = {'A': '#ffaaa6','B': '#ffaaa6','C': ''#2a0aa1','D': '#'#2a0aa1','E': '#3b9ef5','F': '##3b9ef5','G': '#3b9ef5','H': '#3b9ef5'}
# clustering nodes by color: dictionary mapping color to a list of nodes
nodes_by_color = {}
for k,v in nodesWithGroup.items():
if v not in nodes_by_color:
nodes_by_color[v] = [k]
else:
nodes_by_color[v].append(k)
pos = nx.circular_layout(G)
colors2 = list(nodes_by_color.keys())
# print(colors)
# print(colors2)
angs = np.linspace(0,2*np.pi,1+len(colors2))
repos = []
rad = 5.5
for ea in angs:
if ea > 0:
repos.append(np.array([rad*np.cos(ea),rad*np.sin(ea)]))
for color,nodes in nodes_by_color.items():
posx = colors2.index(color)
for node in nodes:
pos[node] += repos[posx]
fig,ax = plt.subplots(figsize=(20,20))
