用于align=left多行节点

Question

我想在右侧写下有关四分之一圆的信息。

我希望它是这样的：

我希望它保持一致，并且尽可能实际地做到这一点。

\documentclass[12pt, border=50mm]{standalone}
\usepackage{tikz}
\usepackage{tkz-euclide}
\begin{document}
\begin{tikzpicture}
\tkzDefPoint(0,0){A},
\tkzDefPoint(4,0){B},
\tkzDefPoint(0,4){C},
\draw [black, very thick] (A)--(0:4) arc[radius=4, start angle=0, end angle= 90]--(C)--(A)--cycle;
\node at (5,4) {$x+y+z=1$};
\node at (5,3) {$text$};
\node at (5,2) {$2x^2=3$};
\node at (5.6,1) {$4x+5x-4=0$};
\end{tikzpicture}
\end{document}

Answer 1

一些备注：您不需要加载，TikZ因为tkz-euclide使用。除非您使用来自的代码，否则TikZ您不需要使用。如果您想放置标签，您可以使用，但也可以。;TikZtkzTextnode

\documentclass[border=1cm]{standalone}
\usepackage{tkz-euclide}
\begin{document}
\begin{tikzpicture}
  \tkzDefPoints{0/0/A,4/0/B,0/4/C}
  \tkzDrawSector(A,B)(C)
  \tkzText[align=left, font={\baselineskip=4ex},
           text width=3cm](6,3)
           {$x+y+z=1$\\$text$\\$2x^2=3$\\$4x+5x-4=0$}
\end{tikzpicture}
\end{document}

Answer 2

这非常简短pstricks：

    \documentclass[svgnames]{article}
    \usepackage{amsmath, array}
    \usepackage{pstricks}

    \begin{document}

    \psset{unit=3cm, linejoin=1}
    \begin{pspicture}(0,0)(2,1)
    \pswedge{1}{0}{90}
    \rput[tl](1,1){$\begin{array}{l}x + y + z = 1 \\ \text{text}\\ 2x^2 = 3 \\ 4x + 5y - 4 = 0\end{array}$}
    \end{pspicture}

    \end{document} 

Answer 3

\documentclass[tikz, border=1cm]{standalone}
\usepackage{tkz-euclide}
\begin{document}
\begin{tikzpicture}
\tkzDefPoint(0,0){A},
\tkzDefPoint(4,0){B},
\tkzDefPoint(0,4){C},
\draw [black, very thick] (A)--(0:4) arc[radius=4, start angle=0, end angle= 90]--(C)--(A)--cycle;
\node[align=left, font={\baselineskip=4ex}] at (6,2.5) {$x+y+z=1$\\$text$\\$2x^2=3$\\$4x+5x-4=0$};
\end{tikzpicture}
\end{document}

Answer 4

这里有两种可能性。在这两种情况下，放置都是从点开始的磷位于四分之一圆弧起点的 1/4 处。由于above right我使用的键（来自positioningTi钾Z 库），明确相对于磷是south west包含文本的矩形节点的锚点。

请注意，您应该删除行后的逗号\tkzDefPoint：每个逗号都会导致警告Missing character: There is no , in font nullfont!打印在 TeX 的标准输出和日志文件上！

用于align=left多行节点

\documentclass[12pt, border=2mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{positioning}
\usepackage{tkz-euclide}

\begin{document}
\begin{tikzpicture}
\tkzDefPoint(0,0){A}
\tkzDefPoint(4,0){B}
\tkzDefPoint(0,4){C}

\draw[black, very thick]
  (A) -- (0:4)
  arc[radius=4, start angle=0, end angle=90] coordinate[pos=0.25] (P)
  -- (C) -- cycle;
\node[align=left, above right=0em and 1em of P]
  {%
   $x+y+z=1$\\[0.5ex]
   \textit{some text}\\[0.5ex]
   $2x^2=3$\\[0.5ex]
   $4x+5x-4=0$%
  };
\fill[blue] (P) circle[radius=3pt] node[below left=2pt of P] {$P$};
\end{tikzpicture}
\end{document}

行距的变体：hpekristiansen'sfont={\baselineskip=4ex} 主意（但是，我建议font={\setlength{\baselineskip}{4ex}}或者font={\baselineskip=4ex\relax}代替）。

tabular在单行节点内使用

\documentclass[12pt, border=2mm]{standalone}
\usepackage{array}
\usepackage{tikz}
\usetikzlibrary{positioning}
\usepackage{tkz-euclide}

\begin{document}
\begin{tikzpicture}
\tkzDefPoint(0,0){A}
\tkzDefPoint(4,0){B}
\tkzDefPoint(0,4){C}

\draw [black, very thick] (A) -- (0:4)
  arc[radius=4, start angle=0, end angle=90] coordinate[pos=0.25] (P)
  -- (C) -- cycle;
\node[above right=0em and 1em of P]
  {%
   \renewcommand{\arraystretch}{1.2}% set row spacing
   \begin{tabular}{@{} l @{}}
     $x+y+z=1$\\
     \textit{some text}\\
     $2x^2=3$\\
     $4x+5x-4=0$
   \end{tabular}%
  };
\fill[blue] (P) circle[radius=3pt] node[below left=2pt of P] {$P$};
\end{tikzpicture}
\end{document}
