Il est aussi empaqueté dans la plupart des distributions GNU/Linux. Python Advanced: Graphs in Python: NetworkX, when I pass multigraph numpy adjacency matrix to networkx (using from_numpy_matrix function)and then try to draw the graph using matplotlib, it ignores the What is this? Comment faire pour forcer tous les graphiques partagent la même position pour les nœuds avec la même étiquette lorsque nous intrigue tous avec nx.draw_networkx(G) nx.draw_networkx(H) nx.draw_networkx(F) plt.show()?Je veux dire, les coordonnées du nœud 1 doit être la même pour tous les 3 graphiques. from networkx.algorithms import bipartite X, Y = bipartite.sets(CBG) cols = ["red" if i in X else "blue" for i in CBG.nodes() ] nx.draw(CBG, with_labels=True, node_color= cols) The grid graph on the other hand is better drawn with the Kamada-Kawai layout in order to see the grid sturcture: nx.draw_kamada_kawai(GG) Nodes Attention : il semblerait que ce module doit être retéléchargé à chaque séance. If the corresponding optional Python packages are installed the data can also be a NumPy matrix or 2d ndarray, a SciPy sparse matrix, or a PyGraphviz graph. neato -T png multi. dot > multi. Ainsi, pour l'installer proprement sous Debian/Ubuntu : $ sudo apt-get install python-networkx Exemple de base. def read_dot (path): """Return a NetworkX MultiGraph or MultiDiGraph from a dot file on path. read ('samplike2.txt')) # read info file e3 = cStringIO. A networkx graph **kwargs: optional keywords. networkx支持创建简单无向图、有向图和多重图(multigraph);内置许多标准的图论算法,节点可为任意数据;支持任意的边值维度,功能丰富,简单易用。networkx以图(graph)为基本数据 . Networkx draw multigraph. Data to initialize graph. Draw the edges of the graph G. draw_networkx_labels (G, pos[, labels, ...]) Draw node labels on the graph G. draw_networkx_edge_labels (G, pos[, ...]) Draw edge labels. The questioner uses the MultiGraph object, however, the actual graph is not a multigraph. Next topic.
