丑陋的双坐标图

由于某种原因，这段代码生成的图看起来非常丑陋。这两个系列看起来像是手绘的。我以为这个smooth属性会有所帮助，但图仍然很丑陋。

\documentclass[8pt]{beamer}
\usepackage{pgfplots}

\begin{document}
\begin{frame}
\begin{tikzpicture}
\begin{axis}[domain=-0.015:1.15,
    width=10cm,
    scale only axis,
    xmin=-0.015,
    xmax=1.15,
    height=8cm,
    axis y line=left,
    xlabel=$x_{\alpha}$,
    ylabel=$y_{j}$]
    \addplot [id=logit,color=blue,thick,smooth,mark=x] coordinates   {(-0.0148,-1.56862) (0.02902,-3.28582)(0.06382,-3.28582)(0.12780,-2.56495)(1.13767,-3.33220)};
\end{axis}
\begin{axis}[domain=-0.015:1.15,
    width=10cm,
    scale only axis,
    xmin=-0.015,
    xmax=1.15,
    height=8cm,
    axis y line=right,
    axis x line=none,
    ylabel=$\tau_{j}$]
    \addplot [id=txdef,color=green,thick,smooth,mark=*] coordinates   {(-0.0148,0.17241) (0.02902,0.03571)(0.06382,0.03571)(0.12780,0.07143)(1.13767,0.03448)};
\end{axis}
\end{tikzpicture}


\end{frame}

\end{document}

这是我删除两个键后情节的样子smooth。这是你想要实现的吗？如果不是，你希望情节是什么样子的？

\documentclass{beamer}
\usepackage{pgfplots}

\begin{document}
\begin{frame}
\begin{tikzpicture}
\begin{axis}[domain=-0.015:1.15,
    width=8cm,
    scale only axis,
    xmin=-0.015,
    xmax=1.15,
    height=8cm,
    axis y line=left,
    xlabel=$x_{\alpha}$,
    ylabel=$y_{j}$]
    \addplot [id=logit,color=blue,thick,mark=x] coordinates   {(-0.0148,-1.56862) (0.02902,-3.28582)(0.06382,-3.28582)(0.12780,-2.56495)(1.13767,-3.33220)};
\end{axis}
\begin{axis}[domain=-0.015:1.15,
