如何使用 `tikzpicture` 环境通过一组彩色箭头连接 `pic`

这是上一个问题的附录：如何确定节点以减少其使用tikzpicture环境的长度，我们需要使用另一个问题：使用调色板从一个节点到多个其他节点绘制多个箭头。

我想要的是

我需要使用从红色到其他颜色的调色板来连接两张图片（主题）。我在用tikz。

每个主题可以有多个外向箭头，但每个箭头只能有一种颜色。但是，不同主题的颜色会有所不同（根据绘制的主题数量，如果总共n只有n-15箭头，则颜色会有所n-15不同，在所选颜色的调色板中均匀分布）：

例子

（取自marmot 的回答）

我想明确指出这些箭头看起来应该像其他箭头（但弯曲）：

我想要的概念

（取自另一只土拨鼠的回答）

每个节点代表一个主题。代码应尽可能自动化。

我做了什么

我借用了以下代码土拨鼠作为第一个附加问题的答案发布并做了一些更改：

我做了什么

请注意最后几行（从#261到#290）。

变化：

  • 用数值（ 等）重命名每个(0)主题(1)。
  • node改变定义和注释中“to”的含义，subject使其更具描述性。
  • 要关联的主题列表已经制作好（共有 5 条线，因为它们是 5 个带箭头的主题）。
  • 删除了绘制箭头的（旧）方法。
  • 删除了长箭头样式，称为manoooh curve。

问题：

  • 当我编译源代码时，我得到了一个pic已绘制所有传出箭头的程序。不同颜色的箭头必须指向各自的主题。
  • 由于蓝色箭头太长，我收到“尺寸太大”的错误。
  • 土拨鼠通过创建新类型的曲线解决了之前的问题：manoooh curve，这对于消除错误是必要的。但是，我无法将两种设计放在同一个循环中，因为我不知道这会如何影响箭头的颜色。
  • 如果您发现任何您认为可能对视觉设计更好的改进，那就继续吧！

我们如何实现一种可以解决这些问题的算法？

谢谢！！

我不明白你为什么要重新绘制节点而不是连接现有节点。我所做的只是改变这一点。
