希望您能帮我解答这个问题，如果这个问题同时包含多个问题，我深表歉意。我不知道如何以我需要的方式显示多个实验的比较。
我正在为几个实验做这个。我改变了 ymin 和 ymax 的值，因为（最大值）一个没有出现，或者其他值重叠。
在一些实验中，我要比较的值有时会太大。下面是我遇到错误的一个实验Dimension too large。所以我想知道 ymin 和 ymax 是否可以动态更改，因为我有 18 个参数，我将像这样进行比较，再次感谢
感谢 Excelsior 的帮助，到目前为止我已经完成了一些实验，但是其他具有较大值的实验变得过于拥挤或重叠。
第一个没问题，因为值很小（x 轴值需要间距），第二个不起作用，如您所见。任何帮助都将不胜感激。

关于评论中提出的问题：
问题 1 您如何根据值来关注这一点，例如，我有另一个想要比较的参数，并且值要大得多（我假设它是 ymin 和 ymin）我们有什么办法可以动态地改变它吗？
如果你指的是箭头：\draw[-stealth, thick, red] (axis cs:1st x value + 0.25, start y value) -- (axis cs:2nd x value - 0.25, end y value);如果你改变，命令就可以进行调整x and y values。
第二季度 我们如何增加 y 轴值之间的距离 - xlabels 需要为我更改并且它们重叠？
如果您指的是 x 轴标签，您可以增加坐标的 x 值（以及 xmin 和 xmax 值）以实现更高的水平偏移。
否则，请参阅评论...

因此，我的新尝试是分别绘制三个图，然后使用calc库将它们粘贴在一起。如果垂直方向太高，您可以在每个环境中定义一些heigth和来调整它。widthaxis
