有人可以帮我创建一个由 Origin Lab 生成的如图所示的图形吗？
根据Jack的建议，我按照如下方式制作了我的tex代码。最后要做的就是图例。虽然Jack已经告诉了我方法，但我还是不知道如何制作这个图例。

答案1
\addlegendimage{<plot options>} \addlegendentry{<legend text>}要获得不同轴的单个图例，您需要通过对最终轴上的每个图例说一次来组装图例。
您不必手动指定<plot options>: 相反，您可以\label{<plot name>}直接在每个\addplot命令后面放置。然后，您只需说一下\addlegendimage{refstyle=<plot name>}即可激活绘图样式。
（我也稍微清理了一下你的代码）
