我试图展示当某些节点被移除时立方体结构的演变。这是我的初始图表：

这给了我以下图像：
现在，我使用它作为模板，并从本质上删除了节点：2、5、6 和 8（以及它们各自的边）：

这给出了以下结果：
奇怪的是，节点和格式之间的距离似乎不对，而且图的右侧有一大片额外的空白。
我希望基本保持第一幅图的尺寸和所有内容不变，但隐藏节点和边，其他所有内容保持不变。标记为 111 和 101 的节点之间的尺寸应保持不变，所有剩余标签也应保持原样。我还想摆脱那一团乱麻，这样我就可以轻松地将它们包含在演示文稿和文档中，而不必考虑右侧的所有额外空间。
答案1
问题在于它们的nodes尺寸不为零，并且这些尺寸进一步拉大了图表的间距。您可以通过保留节点100但使其不可见来解决这个问题。
