以下代码来自这个问题的答案问题和这个问题。

我想修改一些单独的参数，但我无法做到：

  1. 如何控制个别引脚颜色和距离（节点B*的引脚应该是红色）（节点B的引脚应该更长）
  2. 如何控制某些单独的圆圈颜色（节点 B* 的圆圈应该是红色）

  3. 如何控制一些单独的文本框大小（点 12,18 处的框宽度应该具有不同的宽度和颜色）

答案1

您可以定义一些新样式，并在 中使用它们，而不是对值进行硬编码aligned pin。然后，您可以根据需要在本地修改这些样式。

对于应该是红色的黑点，因为它是作为单独的添加的\addplot，您只需添加red到那里的选项即可。（请注意，我dot从节点中删除了，当您已经用图制作了这些点时，添加这样的点似乎毫无意义。）

代码里有一些注释，有什么不清楚的可以问。

如果您想要完全控制每个点的外观，您也可以重新添加样式dot，然后使用\node [dot, aligned pin=...。然后，您只需添加选项即可dot控制这些内容，例如\node [dot, minimum size=30pt, blue, aligned pin=...制作一个巨大的蓝点。

要更改绘制标记的大小，请使用mark size，即\addplot [..., mark size=10pt] ...。请注意，mark size设置半径，而minimum size（对于节点）设置直径。

我dot这里稍微修改了一下。
