没有重叠边缘与定位节点

Question

无重叠选项（overlap = false）和定位（＆＃34; -n2＆＃34;命令行参数）不兼容。

strict graph {
  overlap=false;
  1 [label="", xlabel=<<FONT POINT-SIZE="7">1</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="120.4,31.1!"];
  2 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">2</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="73,35.5!"];
  3 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">3</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="236.2,35.2!"];
  4 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">4</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,100!"];
  5 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">5</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,90!"];
  6 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">6</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,80!"];
  1 -- 4 [arrowhead=none, shape=none];
  2 -- 5 [arrowhead=none, shape=none];
  3 -- 6 [arrowhead=none, shape=none];
}

执行以下命令行时：

neato -n2 -Tpng -ographviz-overlap-test.png graphviz-overlap-test.dotty

我得到了以下结果：

您是否知道生成与无重叠边连接的节点图的替代解决方案？

提前致谢，

只要您告诉graphviz节点的确切位置，就没有机会避免与您正在使用的代码重叠。我手动交换了节点1和2的位置，这样就重新排序了节点。我猜你用其他软件生成dotty文件，这是罪魁祸首。

strict graph {
  overlap=false;
  1 [label="", xlabel=<<FONT POINT-SIZE="7">1</FONT>>,
    shape=circle, style=filled, width=0.05, pin=true, pos="73,35.5!"];
    #                                                 ^^^^^^^^^^^^^^
  2 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">2</FONT>>,
    shape=circle, style=filled, width=0.05, pin=true, pos="120.4,31.1!"];
    #                                                 ^^^^^^^^^^^^^^^^^
  3 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">3</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="236.2,35.2!"];
  4 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">4</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,100!"];
  5 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">5</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,90!"];
  6 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">6</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,80!"];
  1 -- 4 [arrowhead=none, shape=none];
  2 -- 5 [arrowhead=none, shape=none];
  3 -- 6 [arrowhead=none, shape=none];
}
