如何与花键NEATO使用，并避免相互重叠的边缘？(how to use neato with spl

我有我需要有自己的位置固定〜20个节点的有向图。所以，我使用NEATO生成我的SVG文件。问题是，如果我用直线，我有边缘重叠的一些节点。如果一组-Gsplines =真-Gsep = 1个的边缘避免节点很好，但它们的相互节点（也就是，从节点 - > B和B - >一个）显示在彼此的顶部...下面是一块它，例如，在边缘9 - > 12和12 - >是完全重叠。有谁知道解决的办法？我可以用直线跨越节点走了，但如果我能设法避免他们有共同的边缘分开显示，将是理想的。不幸的是，使用普通的点是不是一种选择，因为节点的固定位置是必要的，因为我的最终目标是把这个在地图上（这我做“手”使用Inkscape）的顶部。在其他语言解决方案（举例，如果可能的话），也很受青睐。

Answer 1:

这可能是与graphviz的特定版本的一个问题 - 这里的输出我得到2.28，并且它不会显示你所提到的问题。

我说干脆splines=true; sep=1; splines=true; sep=1; 在图中。

Answer 2:

我安装的版本2.28，并得到了相同的结果，你为这个样本数据。不幸的是，全套它打破了。如果没有花键=真它工作正常（用直线重叠的节点，像往常一样）。但是，当我设置的花键= TRUE，月= 1它无法正确生成SVG。没有-Tsvg运行过程中出现了，我得到启动内存相关的错误很喜欢这样的：
