GraphViz:压缩自动生成的图形 [英] GraphViz: Compress automatically generated graph

问题描述

我正在尝试可视化一个Excel文件的两列:A列包含类别，而B列包含单个条目.点文件由Excel使用以下公式生成:

I am trying to visualize two columns of an an Excel file: Column A contains categories, while Column B contains individual entries. The dot file is generated by Excel using the following formula:

=IFERROR(CONCATENATE("subgraph cluster_",A2,"{""",B2,"""","; label =""",A2,"""}"),"")

然后，使用"unflatten"实用程序更均匀地分布节点，最后使用"dot"生成图

Afterwards the "unflatten" utility is used to distribute the nodes more evenly, and finally the "dot" is used to generate the graph

unflatten.exe -f -l 4 -c 6 -o FLATTENED.dot INPUTFILE.dot
dot -Tpng FLATTENED.dot > FLATTENED.png

生成以下图形

我想使图形更紧凑，并使类别与页面的上部对齐，我应该查看哪些命令来改善结果输出?

I would like to make the graph more compact, and align the categories to the upper egde of the page, what commands should I look into to improve the resulting output?

我已附加点文件

推荐答案

这是个主意:

• 创建一个带有x个图的点文件，而不是一个带有x个簇的图
• 解压它们
• 然后使用gvpack将所有图形打包在一起
• 和整齐的布局

• Instead of one graph with x clusters create a dot file with x graphs
• unflatten them
• then use gvpack to pack all graphs together
• and neato to layout

基本思想是使用图形而不是群集，因此您可以使用gvpack打包图形.

The basic idea is to use graphs instead of clusters so you can use gvpack to pack the graphs.

类似的东西:

unflatten -f -l 4 -c 6 input.dot | dot | gvpack -array_t6 | neato -s -n2 -Tpng -o output.png

不确定是否unflatten处理带有多个图形的文件.

Not sure though whether unflatten handles files with several graphs.

(对不起，没有时间检查它).
