定位 pgfplots 双列环境

Question

我通常通过 来制作图表pgfplots。但是，我在环境中遇到了对齐问题twocolumn。事实上，如果我只生成一个图表，结果会与列正确对齐。当我在环境中执行此操作时，subfloat图表不会与单个图表对齐。我想知道是否有办法将 subfloat 环境中的图表与单个图表对齐。此外，有效图表的大小（不考虑标签）取决于标签本身（例如，当标签包含积分符号时）。有没有办法修复“有效”图表的大小？

下面举个例子来说明

\documentclass[twocolumn,10pt]{article}

\usepackage{blindtext}
\usepackage{graphicx}
\usepackage{subcaption}
\usepackage{pgfplots}


\begin{document}

\begin{figure*}[!h]
\centering
\subfloat[graph A]
{
\begin{tikzpicture}
\begin{axis}[
    width=0.36\textwidth,
    height=0.27\textwidth,
]

\addplot [
    domain=-10:10, 
    samples=100, 
    color=red,
]{x^2 - 2*x - 1};
\addlegendentry{\(x^2 - 2x - 1\)}


\end{axis}
\end{tikzpicture}}
%\hspace{3cm}
\subfloat[graph B]
{\label{fig:totalTemperatureAmp}
\begin{tikzpicture}
\begin{axis}[
    width=0.36\textwidth,
    height=0.27\textwidth,
]

\addplot [
    domain=-10:10, 
    samples=100, 
    color=red,
]{x^2 - 2*x - 1};
\addlegendentry{\(x^2 - 2x - 1\)}


\end{axis}

Answer 1

您可以尝试使用两个subfigure环境，并将其宽度设置为\columnwidth，并在\hfill它们之间使用。注意，我还使用了\columnwidth尺寸axis。

关于您的最后一个问题，您是否在寻找scale only axis选项？即，使用\begin{axis}[scale only axis, width=5cm]，5cm 单独确定轴框的大小，无需标签。

    samples=100, 
    color=red,

\addlegendentry{\(x^2 - 2x - 1\)}
