大标题与轴的数字重叠

Question

代码：

\begin{document}
\usepackage{tikz}

\begin{figure}
\begin{center}
\begin{tikzpicture}[scale=1.2]
  \begin{axis}[
    title=Oxford CROW features Parallel Search,
    xlabel=$Threads$,
    ylabel=$Time$ (sec),
    legend pos=north east]
    \addplot coordinates {
        (1, 3.18099e-05)
    (2, 3.02396e-05)
    (4, 1.05439e-05)
    };
    \addplot [red,mark=triangle] coordinates {
        (1, 0.000515463)
    (2, 0.000272568)
    (4, 0.000166557)
    };
     \addplot [green,mark=square] coordinates {
        (1, 0.000517588)
    (2, 0.000410064)
    (4, 0.000166227)
    };
  \addlegendentry{$threshold = N * 1\%$}
  \addlegendentry{$threshold = N * 5\%$}
  \addlegendentry{$threshold = N * 10\%$}
  \end{axis}
\end{tikzpicture}
\end{center}
\caption{Oxford CROW features, $N$ = 5063, $D$ = 512, Parallel Search.}
\label{crowParSearch}
\end{figure}

\end{document}

输出（注意标题如何与该数字重叠）：

关于如何让这种重叠消失，您有什么想法吗？

Answer 1

• 使用该width选项可使图例更宽。这也为图例提供了更多空间，使其不会与图例重叠。

• 添加\pgfplotsset{compat=1.14}（或无论您使用哪个版本，请参阅日志文件中的注释）以使 y 轴的标签移动得更近。

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\begin{document}
\begin{figure}
\begin{center}
\begin{tikzpicture}
  \begin{axis}[
    width=10cm,
    title=Oxford CROW features Parallel Search,
    xlabel=$Threads$,
    ylabel=$Time$ (sec),
    legend pos=north east]
    \addplot coordinates {
        (1, 3.18099e-05)
    (2, 3.02396e-05)
    (4, 1.05439e-05)
    };
    \addplot [red,mark=triangle] coordinates {
        (1, 0.000515463)
    (2, 0.000272568)
    (4, 0.000166557)
    };
     \addplot [green,mark=square] coordinates {
        (1, 0.000517588)
    (2, 0.000410064)
    (4, 0.000166227)
    };
  \addlegendentry{$threshold = N * 1\%$}
  \addlegendentry{$threshold = N * 5\%$}
  \addlegendentry{$threshold = N * 10\%$}
  \end{axis}
\end{tikzpicture}
\end{center}
\caption{Oxford CROW features, $N$ = 5063, $D$ = 512, Parallel Search.}
\label{crowParSearch}
