如何改变 \tkzAxeXY 尖端的距离？

Question

我目前正在尝试改善形象de.wikipedia.org/wiki/Datei:TrigEinheitskreis.png/ 创建它的免费版本。

这是我目前得到的：

\usetikzlibrary{angles,quotes}

\usetkzobj{all}

    % Mark angle
    \tkzMarkAngle[arc=l,size=0.6cm,fill=green!30](B,A,C)
    \tkzLabelAngle[pos=0.15](B,A,C){$\alpha$}

    % Draw polygon
    \tkzDrawPolygon(A,B,C)
    \tkzDrawSegment[black!60!green,very thick](A,B)
    \tkzDrawSegment[red,very thick](B,C)

    % Label lines
    \tkzLabelSegment[above](A,C){$1$}

问题

我不喜欢 x 轴和 y 轴的尖端相距多远。我该如何改变这种情况？

Answer 1

将选项添加[up space=y,right space=x]到\tkzAxeXY。x和y应该（显然）是无单位数字，和表示轴线延伸超出最大值的长度（以厘米为单位）。据我了解。

label options可以使用键修改刻度标签的样式\tkzAxeXY，因此label options={fill=none}将删除填充。

手册第 6 节对此进行了记录tkz-base，宏命令。请注意，这\tkzAxeXY是四个宏的组合\tkzDrawX\tkzDrawY \tkzLabelX\tkzLabelY，因此如果您查看第 6 节并找到这四个宏的描述，您就会知道可以为轴使用哪些选项。该手册是法语的，因此了解该语言是一种优势，尽管您可以通过查看示例以及键名称为英语的事实来取得很大进展。（我不懂法语。）

Answer 2

仅需tikz

\documentclass[border=2mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{angles,quotes}

\usetikzlibrary{shapes, calc, decorations}
\usepackage{amsmath,amssymb}
\usepackage{helvet}
\usepackage[eulergreek]{sansmath}
\begin{document}
\begin{tikzpicture}[very thick,font=\sansmath\sffamily,x=3cm,y=3cm]
  \coordinate[label={below left:0}] (A) at (0,0);
  \coordinate (B) at (30:1);
  \coordinate (c) at (1,0);

  \draw [help lines] (-1,-1) grid (1,1);  
  \draw[-latex] (0,-1) -- (0,1.2)node[left]{$y$};  
  \path pic[draw=black,fill=green!30, angle radius=10mm,"$\alpha$",angle eccentricity=0.7] 
                                    {angle = c--A--B};  
  \draw (A) -- (B);
  \draw[red] (B) -- ($(A)!(B)!(c)$) node[pos=0.5,above=0.13cm,rotate=180,sloped]{$\sin(\alpha)$}
                                    coordinate (C);
  \draw[-latex] (-1,0) -- (1.2,0)node[below]{$x$};
  \draw[black!60!green] (A) -- (C)node[pos=0.5,below]{$\cos(\alpha)$};

  \draw circle (1);
  \node [anchor=north east] at (-1,0) {$-1$}; 
  \node [anchor=north west] at (1,0) {$1$};
  \node [anchor=north east] at (0,-1) {$-1$}; 
  \node [anchor=south east] at (0,1) {$1$};  
\end{tikzpicture}
\end{document}
