我正在使用以下命令生成图表：
cat mapper.dot | circo -Tpng >output.png
其中mapper.dot是具有上述内容的文件。
问题是节点之间有很多空间。我的意思是很多。有没有办法减少空间？
答案 0 :(得分：1)
我找到了它！
设置＆＃34;思想家＆＃34;设置为数字＆lt; 1
例如：
graph z {
layout="circo"
mindist=.3
a -- b
a -- c
a -- d
}
我通过查看Circo source code
找到了这个答案 1 :(得分：0)
根据dot文件的输出判断，我不确定circo是否可行。我个人会改用sfdp。
如果我删除uuoc并使用以下命令创建图像：
sfdp -Tpng -Goverlap=false -o output.png mapper.dot
您将获得没有节点重叠的较短边，但另一方面，边将与节点重叠。为了摆脱这种情况，您可以通过添加
来启用样条线-Gsplines=true
命令。
输出远远不够完美，但对我来说它看起来比以前更具吸引力。
