使用 TikZ 的故障树：在多个级别绘制子树

在 TiKZ 示例中的故障树线上（http://www.texample.net/tikz/examples/fault-tree/），我制作了以下故障树

 \node (g1) [event] {Project fails \\ E0}
            child {node (e1) {No legal permit \\(E1)}
                child {node (e11) {No legal permit A \\ (E11)}}
                child {node (e12) {No legal permit B \\ (E12)}}
                child {node (e13) {No legal permit C \\ (E13)}}
            }
        child {node (e2) {No financing \\(E2)}
            child {node (e21) {No financing A \\ (E21)}}
            child {node (e22) {No financing B \\ (E22)}}
            child {node (e23) {No financing C \\ (E23)}}
        }
        child {node (e3) {No collaboration}
            child {node (e31) {Low incentive}}
            child {node (e32) {Low trust}}
        };

但是树的节点相互重叠。我尝试减少节点之间的距离，但在这种情况下看起来不太优雅。有没有办法让 E2 子树处于比 E1 子树更低的级别？ 在此处输入图片描述

答案1

这就是你想要的吗？看来你的代码没有反映你发布的图像。此解决方案已尝试生成你想要的图像并将 E2 子树移到低于 E1 子树的位置。这是通过使用节点[level distance=xx]处的选项实现的e2。

child[level distance=70mm]  {node (e2) {No financing \\(E2)}

如果希望将 E3 子树稍微向左移动，则适用相同的想法。但[sibling distance=xx]在这里使用

child[sibling distance=30mm] {node (e3) {No collaboration}

如果不需要门，则删除最后一部分的代码。
