dot / Graphviz的更紧凑的分层布局

时间：2013-06-17 14:59:17

标签： graphviz dot

我使用点生成以下PDF：enter image description here

我的主要问题是，即使在 A3 上打印，字符尺寸也太小。此外，似乎可以使图形更紧凑。例如。由于左上角有蓝色，绿色和棕色的节点，宽度会延长，但我看不出为什么整个前两行都不能向右移动，导致至少减少20％宽度。我在最后添加 .gv 文件。

由于我自动生成 .gv 文件，因此我只能修改所有节点和边的图层级属性或属性，或更改点调用，但我可以'微调坐标或特定节点。

你是否看到任何明显的方法我可以获得更紧凑的布局，允许更大的字符大小？

我使用的调用是：

 dot -Gsize="16.52,11.68" -Gratio="fill"  -Glandscape=false -Gsplines=ortho -Tpdf graph.gv -o graph.gv.pdf

graph.gv文件

unflatten实用程序可以生成更紧凑的图形。

尝试以下命令行：

unflatten -f -l 2 graph.gv | dot -Gsize="16.52,11.68" -Gratio="fill"  -Glandscape=false -Gsplines=ortho -Tpdf -o graph.gv.pdf

根据您自动生成的各种图表，可能还有其他一些非平坦值可以覆盖所有这些值。
