我使用 pgfplots 包绘制了两个独立图。我想要这两个图具有相同的高度，但是我失败了。
这是我的论文中显示的图像。
如你所见，右边的比左边的稍微高一点。
我尝试过这些事情：
使用
scaled x ticks=false。此方法可以解决此问题。但是，数字太接近，这是我所不希望的。我怀疑这是由指数引起的。所以我接下来尝试了 2。将指数移动到其他位置
every x tick scale label/.style={ at={(rel axis cs:0.9,-0.2)} }但这个问题还没能解决，它们还是没有达到同样的高度。

它们像这样插入到论文中：
\begin{figure}[htb]
\centering
\subfloat[Performance under different levels of increment noise]{\includegraphics[height=4cm]{incremental_noise/incremental_noise}}
\hspace{.5cm}
\subfloat[Performance under different levels of deviation noise]{\includegraphics[height=4cm]{deviation_noise/deviation_noise}}
\caption{Resistence to different kind of noise.}

您有解决这个问题的办法吗？谢谢！
答案1
我知道该怎么做才能解决这个问题。我添加了\raisebox{-0.25ex}[0pt][0pt]我的主要 tex 文件，结果看起来不错。请参阅此答案更多细节。
