如何在graphviz中隐藏节点边界？

我正在用graphviz画一个图表。即使我为节点设置了

penwidth=0

，我仍然可以看到节点边界。如何消除节点边界

我的dot注释如下所示：

strict graph  {
    graph [bgcolor=white];
    0    [fillcolor=red,
        style=filled,
        shape=octagon,
        penwidht=0,
        fontsize=10,
        fixedsize=True,
        width=0.5,
        height=0.5,
        type=3];
    2    [shape=octagon,
        style=filled,
        fillcolor=gray,
        penwidth=0];
    0 -- 2  [penwidth=0.5,
        color=gray];
}

setlinewidth适用于我：

strict graph  {
    graph [bgcolor=white];
    0    [fillcolor=red,
        style="filled,setlinewidth(0)",
        shape=octagon,
    penwidht=0,
        fontsize=10,
        fixedsize=True,
        width=0.5,
        height=0.5,
        type=3];
    2    [shape=octagon,
        style=filled,
        fillcolor=gray,
        penwidth=0];
    0 -- 2  [penwidth=0.5,
        color=gray];
}

node [shape=plaintext]

这对我很有用：

strict graph  {
    graph [bgcolor=white];
    0    [fillcolor=red,
        style="filled,setlinewidth(0)",
        shape=octagon,
    penwidht=0,
        fontsize=10,
        fixedsize=True,
        width=0.5,
        height=0.5,
        type=3];
    2    [shape=octagon,
        style=filled,
        fillcolor=gray,
        penwidth=0];
    0 -- 2  [penwidth=0.5,
        color=gray];
}

node [shape=plaintext]

问题是你的打字错误

penwidt

应为

penwidth

strict graph  {
    graph [bgcolor=white];
    0    [fillcolor=red,
        style=filled,
        shape=octagon,
        penwidth=0,
        fontsize=10,
        fixedsize=True,
        width=0.5,
        height=0.5,
        type=3];
    2    [shape=octagon,
        style=filled,
        fillcolor=gray,
        penwidth=0];
    0 -- 2  [penwidth=0.5,
        color=gray];
}
