更紧凑的层次布局，适用于dot/Graphviz

graphvizdot

5

我使用dot生成以下PDF： enter image description here

我的主要问题是，即使在A3上打印，字符大小也太小了。此外，图表似乎可以更紧凑。例如，蓝色、绿色和棕色节点位于左上角，导致宽度加大，但我看不到任何理由，不能将前两行整体向右移动，以至少缩小20%的宽度。我在最后附上.gv文件。

由于我自动生成.gv文件，所以我只能修改图形级别属性或所有节点和边的属性，或更改dot调用，但我无法微调坐标或特定节点。

你看到有明显的方法可以使布局更紧凑，从而允许更大的字符大小吗？

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

仅仅增加字体大小不就可以解决问题了吗？ - svick

它确实有一点帮助，但只有当我将其设置为过高的值（例如40个点）时，即使如此，在左上角的反向“L”形蓝绿棕色形状仍然停留在那里，不必要地增加了图表的宽度，当整个前两行都可以向右移动。 - Marcus Junius Brutus

unflatten实用工具可以使图形更加紧凑。尝试下面的命令行：

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

根据生成的各种自动图形，可能有一些其他的unflatten值更适合涵盖它们所有。
