在框图中绘制轴

Question

我想在 TikZ 节点内添加图。这是我已有的代码的最小工作示例。

\documentclass[]{standalone}
\usepackage{pgf,tikz,pgfplots}
\usetikzlibrary{calc,positioning}
\pgfplotsset{compat=1.15}

\begin{document}
\begin{tikzpicture}
\draw node[draw,minimum width=2cm, minimum height=15mm},label=Test] {};
\begin{scope}[x=0.016cm,y=8,shift={(-0.8cm,0cm)}]
\draw[thick] (0,0) plot[domain=0:100,samples=30,mark=none] ({\x},{sin(2*pi*\x)});
\end{scope}
\end{tikzpicture}
\end{document}

MWE 创建了下图：

我想在框图中使用多个这样的节点。是否可以将示波器替换为具有轴线和固定宽度和高度的常规轴，以便简单地将绘图替换为其他绘图而不影响轴的外观？

Answer 1

修改后的版本，框架作为样式的一部分进行绘制simple axis，并且该样式的参数允许您为框架节点指定名称。可以使用库相对于其他节点进行定位calc，但不使用该库的便捷语法positioning（据我所知）。

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots} % loads tikz which loads pgf
\usetikzlibrary{calc,fit}
\pgfplotsset{
  compat=1.15,
  simple axis/.style={
    scale only axis,
    anchor=center,
    axis lines=middle,
    enlargelimits=0.1,
    width=2cm,
    height=15mm,
    xtick=\empty,
    ytick=\empty,
    domain=0:100,
    tickwidth=0,
    clip mode=individual,
    every axis plot/.append style={smooth},
    cycle list={
      black, thick\\
      black, thick, dashed \\
    },
    before end axis/.code={
        \node [draw,fit=(current axis)] (#1) {};
        }
    },
  simple axis/.default=foo
}

\begin{document}
\begin{tikzpicture}
\begin{axis}[ % no position defined, so this ends up at (0,0)
  simple axis=ax1,
  title=Test,
  ]
  \addplot  {sin(2*pi*x)};

\end{axis}

\begin{axis}[
  simple axis=ax2,
  title=Test2,
  at={($(ax1.east)+(1cm,0)$)}, % specify position relative to east anchor of ax1
  anchor=west
  ]
  \addplot {cos(2*pi*x)};
\end{axis}


\draw [red, thick, -stealth] (ax1) -- (ax2);

\end{tikzpicture}
\end{document}

您在寻找类似的东西吗？

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots} % loads tikz which loads pgf
\usetikzlibrary{calc,positioning}
\pgfplotsset{
  compat=1.15,
  simple axis/.style={
    scale only axis,
    width=2cm,
    height=15mm,
    xtick=\empty,
    ytick=\empty,
    domain=0:100,
    tickwidth=0
    }
}

\begin{document}
\begin{tikzpicture}
\begin{axis}[ % no position defined, so this ends up at (0,0)
  simple axis,
  title=Test,
  ]
  \addplot [thick, smooth] {sin(2*pi*x)};
\end{axis}


\begin{axis}[
  simple axis,
  title=Test2,
  at={(3cm,1cm)} % specify position
  ]
  \addplot [thick, smooth] {cos(2*pi*x)};
\end{axis}
\end{tikzpicture}
\end{document}

Answer 2

我可以自己更改 Torbjørn T 的解决方案。我将轴的锚点改为中心，并将其放置在节点的位置。

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots} % loads tikz which loads pgf
\usetikzlibrary{calc,positioning}
\pgfplotsset{
  compat=1.15,
   simple axis/.style={
    scale only axis,
    width=1.7cm,
    height=12mm,
    xtick=\empty,
    ytick=\empty,
    domain=0:100,
    tickwidth=0,
    axis lines=left,
    enlargelimits=upper,
    anchor=center,
    }
}

\begin{document}
\begin{tikzpicture}
\draw node[draw,minimum width=2cm, minimum height=15mm,label=Test] (node1) {};
\begin{axis}[simple axis,at={(node1)}]
  \addplot [thick, smooth] {sin(2*pi*x)};
\end{axis}

\draw node[draw,minimum width=2cm, minimum height=15mm,label=Test 2,right=of node1] (node2) {};
\begin{axis}[simple axis,at={(node2)}]
  \addplot [thick, smooth] {sin(2*pi*x)};
\end{axis}

\draw[->] (node1)-- (node2);
\end{tikzpicture}
\end{document}
