这就是我想要的：https://media-us.amboss.com/media/thumbs/big_58ac9ed16c2bf.jpg

这就是我所拥有的（现在只是第一部分）：

digraph G {

"Palpable breast mass" -> "Age of patient?";
"Age of patient?" -> "Clinical assessment: probability of malignancy?" [label="< 30yo"];
"Clinical assessment: probability of malignancy?" -> "Reexamine 3-10 days after onset of menstruation" [label="Low"];
"Reexamine 3-10 days after onset of menstruation" -> "Ultrasound and/or FNA" [label="Suspicious mass"];
"Clinical assessment: probability of malignancy?" -> "Ultrasound and/or FNA" [label="High"];
"Ultrasound and/or FNA" -> "Mammography" [label="No visualization possible"];
"Age of patient?" -> "Mammography" [label="> 30yo"];
"Mammography" -> "Ultrasound and/or FNA" [label="Inconclusive"];
{rank=1;
"Palpable breast mass";
}
{rank=2;
"Age of patient?";
}
{rank=3;
"Clinical assessment: probability of malignancy?";
}
{rank=4;
"Reexamine 3-10 days after onset of menstruation";
"Ultrasound and/or FNA";
"Mammography";
}
}

但是，排名并没有按照我想要的方式匹配。我希望rank=4 中的所有项目都位于同一水平线/平面上。下面是它的样子：

【解决方案1】：

没关系，我意识到我需要在每个括号中写 rank=same 而不是实际值。像这样：

{rank=same;
"Palpable breast mass";
}
{rank=same;
"Age of patient?";
}
{rank=same;
"Clinical assessment: probability of malignancy?";
}
{rank=same;
"Reexamine 3-10 days after onset of menstruation";
"Ultrasound and/or FNA";
"Mammography";
}
