我有一组/一组曲线的 (x,y) 坐标。每条曲线对应不同的 z 值，但曲线之间的 x 值或 y 值没有相关性。也就是说，我无法将曲线集表示为表格，它实际上是几个 x,y 对列表。
我想尝试将曲线做成 3d 形式，看看这样是否更易于阅读，以及是否可以从此消除对颜色编码的需求。我希望避免使用颜色编码，以更好地照顾色盲观众，同时实现黑白打印。
下面是 latex 代码。有人能建议一种将其转换为 3d 图像的方法吗？我是否需要重新开始并使用完全不同的包，或者我是否可以通过一些调整仍然使用 tikzpicture 和朋友来做到这一点？
欢迎提出建议。

答案1
我会采取不同的策略。我会坚持使用 2D 打印页面，但我会利用可编程绘图工具的强大功能“手工”绘制图表，而不是尝试让绘图包自动完成您所需的所有工作。
在这里我用的是元帖子包装在luamplib（因此您需要使用编译lualatex或改编它以适应 Plain MP 或gmp包）。其他人可以向您展示如何使用 TikZ 做类似的事情。
我编写了一个自定义addplot例程来绘制每条曲线。我利用语言的可编程功能来更改每条线的虚线图案，并在需要的地方添加标签，而不是使用笨重的图例。
