我在python中使用graphviz。我尝试模拟能量流程图。所有商品(技术)都在矩形节点中。产生的所有燃料都是椭圆形的。 我想得到一个图表,给我一个更好的alinement,其中第一列应该是矩形,最后一列也应该是矩形。垂直的节奏应该是
矩形 - > Elipse - >矩形 - > Elipse - >矩形 - > Elipse - > 矩形 - > Elipse - >矩形(等)
我该怎么做?我已经检查了文档,但无法找到...

您好我发现它与命令
完美配合B=A.add_subgraph(["IMPOIL1","IMPDSL1","RIV", "IMPURN1", "IMPHCO1", "IMPGSL1"])
B.graph_attr['rank']='same'
等
希望它可以帮助将来的某个人。
