如何在 TikZ 中移动每个图片引用构造中的弧线？

Question

我的代码：

\documentclass{scrartcl}
\usepackage{stanli}
\usetikzlibrary{angles, quotes}
\begin{document}

  \begin{tikzpicture}
    %the points
    \point{begin}{0}{0};
    \point{end}{5}{0};
    %the beam
    \begin{scope}[dashed]
      \beam{2}{begin}{end};
    \end{scope}
    %displaced points
    \point{delta_begin}{.5}{.5};
    \point{delta_end}{5.5}{1};
    %displaced beam
    \beam{2}{delta_begin}{delta_end};
    %virtual displacements
    \dimensioning{2}{begin}{delta_begin}{0}[$\delta y$];
    \dimensioning{1}{begin}{delta_begin}{.5}[$\delta x$];
    \draw
      [dashed] (delta_begin) -- (5.5, .5);
    %angle
    \coordinate (A) at (5.5, .5);
    \coordinate (B) at (delta_begin);
    \coordinate (C) at (delta_end);
    \pic[draw, angle radius = 10mm, "$\varphi$"] {angle};
  \end{tikzpicture}

\end{document}

结果：

我的角度很小。phi 不适合线条之间。因此 phi 和弧应该向右移动。every pic quotes您可以在手册第 255 页的第 18.2.1 节中找到构造的描述TikZ & PGF。或者最好在这里使用arc构造（第 152 页的第 14.7 节）。

提前感谢您的帮助和努力！

Answer 1

angle radius令人惊讶的是，它会改变角度的半径。不太明显的是，angle eccentricity它会影响标签相对于标记角度的线的位置。

\documentclass{scrartcl}
\usepackage{stanli}
\usetikzlibrary{angles, quotes}
\begin{document}

  \begin{tikzpicture}
    %the points
    \point{begin}{0}{0};
    \point{end}{5}{0};
    %the beam
    \begin{scope}[dashed]
      \beam{2}{begin}{end};
    \end{scope}
    %displaced points
    \point{delta_begin}{.5}{.5};
    \point{delta_end}{5.5}{1};
    %displaced beam
    \beam{2}{delta_begin}{delta_end};
    %virtual displacements
    \dimensioning{2}{begin}{delta_begin}{0}[$\delta y$];
    \dimensioning{1}{begin}{delta_begin}{.5}[$\delta x$];
    \draw
      [dashed] (delta_begin) -- (5.5, .5);
    %angle
    \coordinate (A) at (5.5, .5);
    \coordinate (B) at (delta_begin);
    \coordinate (C) at (delta_end);
    \pic[draw, angle radius = 30mm, angle eccentricity=1.2, "$\varphi$"] {angle};
  \end{tikzpicture}

\end{document}
