将情节线延伸至最后一个刻度标记

Question

绘图线结束于属于域的最后一个刻度标记处。是否可以将线条一直延伸到标记之外并到达图表框的边缘？

\documentclass{article}

\usepackage{tikz,pgfplots}

\begin{document}

\begin{tikzpicture}[font=\tiny,scale=2.2]
\begin{axis}[
    axis x line=center,
    axis y line=center,
    restrict y to domain=-50:50,
    legend entries={$d=-2$,$d=-1$,$d=0$,$d=1$,$d=2$},legend pos=north west]
]
\foreach \d in {-2, ..., 2}
{
    \addplot[solid, every mark/.append style={fill=blue}, mark=*, mark size=1]{(x-\d)^3};
}
\end{axis}
\end{tikzpicture}

\end{document}

Answer 1

您可以通过将域明确定义为以下方式获得所需的结果domain=-4:4：

代码：

\documentclass[border=2pt]{standalone}

\usepackage{tikz,pgfplots}

\begin{document}

\begin{tikzpicture}[font=\tiny,scale=2.2]
\begin{axis}[
    axis x line=center,
    axis y line=center,
    restrict y to domain=-50:50,
    legend entries={$d=-2$,$d=-1$,$d=0$,$d=1$,$d=2$},legend pos=north west]
]
\foreach \d in {-2, ..., 2}
{
    \addplot[solid, every mark/.append style={fill=blue}, mark=*, mark size=1, domain=-4:4]{(x-\d)^3};
}
\end{axis}
\end{tikzpicture}

\end{document}
