我们从Python开源项目中，提取了以下4个代码示例，用于说明如何使用networkx.fruchterman_reingold_layout()。
def save(self, path='out.png'): import networkx import matplotlib.pyplot as plt pos = networkx.spring_layout(self.graph, iterations=500) # pos = networkx.spectral_layout(self.graph) # pos = networkx.shell_layout(self.graph) # pos = networkx.fruchterman_reingold_layout(self.graph) nodelist = list(range(self.num_rooms)) networkx.draw_networkx_nodes(self.graph, pos, nodelist=nodelist) edgelist = sorted(self.edges - self.secret_edges) secret = sorted(self.secret_edges) networkx.draw_networkx_edges(self.graph, pos, edgelist=edgelist, edge_color='k') networkx.draw_networkx_edges(self.graph, pos, edgelist=secret, edge_color='r') networkx.draw_networkx_labels(self.graph, pos, self.labels) plt.savefig(path)
