dot / Graphviz 的更紧凑的层次布局

Question

我用dot生成以下 PDF ：

我的主要问题是即使在A3上打印，字符尺寸也太小。此外，图表似乎还可以变得更紧凑。例如，左上角存在蓝色、绿色和棕色节点，从而扩展了宽度，但我看不出为什么整个前两行不能向右移动，从而导致至少减少 20%的宽度。我在最后附上了.gv文件。

由于我自动生成.gv文件，因此我只能修改图形级属性或所有节点和边的属性或更改点调用，但无法微调坐标或特定节点。

您是否看到任何明显的方法可以让我获得更紧凑的布局，从而允许更大的字符尺寸？

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

该unflatten实用程序可以生成更紧凑的图表。

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

根据您的各种自动生成的图形，也许其他一些 unflatten 值更适合覆盖所有这些值。
