Matplotlib：如何保存交互式networkx图？

如何解决Matplotlib：如何保存交互式networkx图？

我创建了一个具有悬浮功能的加权networkx图，该图显示每个节点的所有连接。保存绘图时，我得到一个静态的PNG图像。我想问一下我是否可以通过悬停功能保存该图，以便与他人共享？

这是我的代码：

import matplotlib.pyplot as plt
import networkx as nx
import numpy as np

G = nx.Graph()

G.add_edge("Ted","May",weight=0.5)
G.add_edge("Ted","Ray",weight=1)
G.add_edge("Ted","Chris","Sam",weight=3)
G.add_edge("Ted","April","Ana",weight=0)


G.add_edge("Ana","Ryan",weight=1)
G.add_edge("Ana","Jim",weight=0.5)
G.add_edge("Ana","Ben",weight=1)


for0 = [(u,v) for (u,v,d) in G.edges(data=True) if d["weight"] == 0]
for05 = [(u,d) in G.edges(data=True) if d["weight"] == 0.5]
for1 = [(u,d) in G.edges(data=True) if d["weight"] == 1]
for15 = [(u,d) in G.edges(data=True) if d["weight"] == 1.5]
for3 = [(u,d) in G.edges(data=True) if d["weight"] == 3]



fig,ax = plt.subplots(figsize=(7.2,7.2))
pos = nx.circular_layout(G)  # positions for all nodes
names = np.array(["Ted","Ben"])

# nodes
sc = nx.draw_networkx_nodes(G,pos,node_size=700)

# edges


nx.draw_networkx_edges(G,edgelist=for0,width=0)
nx.draw_networkx_edges(G,edgelist=for05,width=0.5)

nx.draw_networkx_edges(G,edgelist=for1,width=1)
nx.draw_networkx_edges(G,edgelist=for15,width=1.5)

nx.draw_networkx_edges(G,edgelist=for3,width=3)


# labels
nx.draw_networkx_labels(G,font_size=20,font_family="sans-serif")

annot = ax.annotate("",xy=(0,0),xytext=(20,20),textcoords="offset points",bbox=dict(boxstyle="round",fc="w"),arrowprops=dict(arrowstyle="->"))
annot.set_visible(False)

def update_annot(ind):

    pos = sc.get_offsets()[ind["ind"][0]]
    annot.xy = pos
    es = [e for e in G[names[ind["ind"]][0]]]
    text = "{}".format(es)
    annot.set_text(text)
    annot.get_bbox_patch().set_alpha(0.4)
    return sc


def hover(event):
    vis = annot.get_visible()
    if event.inaxes == ax:
        cont,ind = sc.contains(event)
        if cont:
            update_annot(ind)
            annot.set_visible(True)
            fig.canvas.draw_idle()
        else:
            if vis:
                annot.set_visible(False)
                fig.canvas.draw_idle()

fig.canvas.mpl_connect("motion_notify_event",hover)
plt.show()

谢谢。

解决方法

如果您不想重写代码，可以将其保存在GEXF中，以便其他人可以在Gephi中打开它：

nx.write_gexf(G,"test.gexf")

或者，如果要将其存储在HTML文件中，则需要使用其他plotly之类的绘图API，该API支持交互式绘图（see here for some examples）。
