散点图使用 Pgfplots 在线条顶部添加 ax 线

Question

我想在图片1就像图片-2。我还想删除用圆圈标记的箭头。任何建议或完整的代码都将不胜感激。

图片1 代码

%-------------------------------------------
\begin{axis}
  [
  grid = both, %grid in the picture
  height=10cm, %height of the figure
  width=\textwidth,
  axis x line=middle,%remove the top x axis line
  legend style={draw=none}, %remove the box, options- none, white, black
  %-------------------------------------------
  xlabel style={xshift=-4.2cm}, %shifting the x line text -0.2
  xlabel style={yshift=-1.2cm}, %shifting the x line text -0.2
  ylabel style={yshift=0.3cm}, %shifting the y line text
  %-------------------------------------------
  ylabel=Accuradfdcy Value {\%},
  xlabel=number of best terms,
 ]

图片-2

Answer 1

CW 来自评论。

要恢复带框的轴，只需删除axis x line=middle。由于我没有您的绘图函数，因此我在此处的代码中使用了示例图。

代码

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.10}

\begin{document}
\begin{tikzpicture}
\begin{axis}
  [
  grid = both, %grid in the picture
  height=10cm, %height of the figure
  width=\textwidth,
%  axis x line=middle,%remove the top x axis line
  legend style={draw=none}, %remove the box, options- none, white, black
  %-------------------------------------------
  xlabel style={xshift=-4.2cm}, %shifting the x line text -0.2
  xlabel style={yshift=-1.2cm}, %shifting the x line text -0.2
  ylabel style={yshift=0.3cm}, %shifting the y line text
  %-------------------------------------------
  ylabel=Accuradfdcy Value {\%},
  xlabel=number of best terms,
 ]
\addplot {x};
\addplot {x^2};
\end{axis}
\end{tikzpicture}%
\end{document}
