使用graphviz繪製晶格時，我如何在節點上施加y位置？

Question

我正在使用Graphviz繪製一個格子。
節點是一組數字。作爲一個點陣，我想要一個節點的高度位置（y）來表示節點表示的集合中元素的數量。然後，x位置應由graphviz定義，以使表示更清晰。

可能嗎？

根據點文檔應該有屬性pos應該定義節點的位置。但儘管我以許多不同的方式嘗試了很多次，但我無法獲得定義節點位置的任何圖形。有沒有人有過這方面的成功？

下面是經典的圓點文件我用：

digraph G { 
"528 544\n640 768" -> "768 528"; 
"528 536\n530 539" -> "539";

} 

如果任何人都可以寫，其中一個節點的高度定義我將非常感激文件的一個例子。

Answer 1

我找到了答案。

這裏： http://www.linuxdevcenter.com/pub/a/linux/2004/05/06/graphviz_dot.html?page=2

本質上講，它可以定義哪些設置節點應在同一HIGHT。 要獲得節點A和B在相同的高度，我需要添加行： {rank = same; A B};

因此，這裏是一個類似的例子作爲一個前，但與樹立正確的節點：

digraph G { 
{rank=same; "768" "944" "539" "528" }; 
{rank=same; "768 539" "768 528" }; 
{rank=same; "768 640\n528 544" "528 536\n530 539" "768 704\n539 548" "944 728\n539 566" "944 656\n528 560" "944 800\n896 768" }; 
{rank=same; "800 896 548\n944 566 728\n539 704 768" "528 944 536\n530 566 560\n728 656 539" "800 896 944\n656 560 528\n544 640 768" "768 640 548\n528 530 544\n536 539 704" }; 
"768 640\n528 544" -> "768 528"; 
"528 536\n530 539" -> "539";
