一.networkx
1.用于图论和复杂网络
2.官网：http://networkx.github.io/
3.networkx常常结合numpy等数据处理相关的库一起使用，通过matplot来可视化图
二.绘制图
1.创建图
1 import networkx as nx 2 import matplotlib.pyplot as plt 3 4 G=nx.Graph()#创建空图，无向图 5 # G1=nx.DiGraph(e)#创建空图，有向图 6 # G = nx.Graph(name=‘my graph‘)#指定图的属性（name） 的值（my graph） 7 G.add_edges_from(([1,2],[2,3],[3,1])) 8 9 e = [(1, 2), (2, 3), (3, 4)] # 边的列表 10 G2 = nx.Graph(e)#根据e来创建图 11 12 F=G.to_directed()#把无向图转换为有向图 13 14 #创建多图，类MultiGraph和类MultiDiGraph允许添加相同的边两次，这两条边可能附带不同的权值 15 # H=nx.MultiGraph(e) 16 H=nx.MultiDiGraph(e) 17 18 plt.subplot(2,2,1) 19 nx.draw(G,with_labels=True) 20 plt.subplot(2,2,2) 21 nx.draw(G2,with_labels=True) 22 plt.subplot(2,2,3) 23 nx.draw(F,with_labels=True) 24 plt.subplot(2,2,4) 25 nx.draw(H,with_labels=True) 26 27 plt.show()
2.无向图
1 import networkx as nx 2 import matplotlib.pyplot as plt 3 4 G=nx.Graph()#创建空图 5 6 #添加节点 7 G.add_node(‘a‘) 8 G.add_node(1) #添加单个节点 9 G.add_nodes_from([2,3,4]) #添加一些节点，容器，（可以是list, dict, set，） 10 11 #添加边，如果点不在图中，会自动创建点 12 G.add_edge(1,‘a‘,weight=1.2) #添加单条边，连接1，‘a’的边,可以赋予边属性以及他的值 13 G.add_edges_from([(2,3),(3,4)])#添加一些边（列表） 14 G.add_weighted_edges_from([(1,‘a‘,0.1),(4,2,0.5)])#给边赋予权重 15 16 #移除边 17 G.remove_edge(2,4) #移除一条边 18 G.remove_edges_from([(3,4),]) #移除一些边 19 20 #移除节点,同时移除他对应的边 21 G.remove_node(1) #移除单个节点 22 G.remove_nodes_from([4,]) #移除一些节点 23 24 #绘图 25 nx.draw(G, # 图 26 pos=nx.circular_layout(G), # 图的布局 27 alpha=0.5, # 图的透明度（默认1.0不透明，0完全透明） 28 29 with_labels=True, # 节点是否带标签 30 font_size=18, # 节点标签字体大小 31 node_size=400, # 指定节点的尺寸大小 32 node_color=‘blue‘, # 指定节点的颜色 33 node_shape=‘o‘, # 节点的形状 34 35 edge_color=‘r‘, # 边的颜色 36 width=0.8, # 边的宽度 37 style=‘solid‘, # 边的样式 38 39 ax=None, # Matplotlib Axes对象，可选在指定的Matplotlib轴中绘制图形。 40 ) 41 42 plt.show()
绘图布局
3.有向图和无向图的最大差别在于：有向图中的边是有顺序的，前一个表示开始节点，后一个表示结束节点。
三.图
