工作流程图中的相对箭头位置

我正在尝试重新创建下面的图像，并对其进行了小幅修改使其垂直。

在此处输入图片描述

然而，我遇到了一些关于箭头长度的小问题，

在此处输入图片描述

有什么想法可以让箭头长度相同，并正确居中吗？是否可以让所有框的高度/宽度也相同？

作为起点（因为我迷失在你的代码中:-(）：

编辑： 再次阅读您的问题后，我意识到您希望所有箭头形状的长度相等，所有块的高度相等（我说得对吗？）。这可以通过text width为箭头规定尺寸并将minimum height其他节点的尺寸放大来获得。更正后的代码：

\documentclass[svgnames, margin=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{positioning, shadows, shapes.arrows, shapes.geometric}

\tikzset{
   arrowstyle/.style n args = {3}{single arrow, single arrow head extend=3mm,
                        minimum width=12mm, text width=24mm,
                        draw=#1, top color=#2, bottom color=#3,
                        drop shadow={shadow xshift=0ex, shadow yshift=-0.8ex},
                        anchor=west
                                 },
 arrowstyle/.default = {red}{OrangeRed!20}{Red},
    startstop/.style = {rectangle, rounded corners, draw=black, fill=red!30,
                        minimum width=33mm, minimum height=22mm, align=left},
           io/.style = {trapezium,
                        trapezium left angle=70, trapezium right angle=110,
                        trapezium stretches body,
                        draw=black, fill=blue!30,
                        minimum width=33mm, minimum height=22mm, align=left},
      process/.style = {rectangle, draw=black, fill=orange!30,
                        minimum width=33mm, minimum height=22mm, align=left},
        }

\begin{document}
    \begin{tikzpicture}[
node distance = 6mm and 9mm]
\node (start)   [startstop]                             {Your computer\\ \\ 3. Update \\ 4. Commit};
\node (push)    [above right=of start.east,
                 arrowstyle, shape border rotate=180]   {2. Clone};
\node (clone)   [below right=of start.east,
                 arrowstyle]                            {5. Push};
%
\node (in1)     [io, right=of clone.east |- start]      {Your GitHub-repo \\
                                            \footnotesize github.com/you/coolproject};
\node (pull)    [above right=of in1.east,
                 arrowstyle, shape border rotate=180]   {1. Fork};
\node (fork)    [below right=of in1.east,
                 arrowstyle]                            {6. Pull request};

  • 在我的代码中删除所有嵌套的tikz图片，重新设计节点样式并统一它们的定义方式（仅使用tikzset），使用tikz库positioning进行节点定位
  • 观察节点处选项的新序列arrowstyle：首先是定位，然后是节点样式。这是必要的，以确保节点锚点不会被定位覆盖

  • 如果您想复制所显示的图像，将上述代码重新排列一下相对简单：

                        drop shadow={shadow xshift=0ex, shadow yshift=-0.8ex},
                        anchor=west
                                 },
   arrowstyle/.default = {red}{OrangeRed!20}{Red},
    startstop/.style = {rectangle, rounded corners, draw=black, fill=red!30,
                        minimum width=33mm, minimum height=22mm, align=left},
           io/.style = {trapezium,
                        trapezium left angle=70, trapezium right angle=110,
                        trapezium stretches body,
                        draw=black, fill=blue!30,
                        minimum width=33mm, minimum height=22mm, align=left},
      process/.style = {rectangle, draw=black, fill=orange!30,
                        minimum width=33mm, minimum height=22mm, align=left},
        }

答案2

如果我理解正确的话，你的问题是控制箭头的长度和方向。这两件事都可以用以下方法解决Torbjørn T. 的回答很棒，我针对当前任务对其进行了修改。您应该能够使用简单的 edge 命令完成所有这些操作

\path
([xshift=7mm]in1.south) edge[fancy arrow={}{5.~Push}] 
([xshift=7mm]start.north);

其中坐标指的是起点和终点（我移动了它们，因为你想要箭头指向相反的方向），第一个参数是一个选项，在大多数情况下你可能不需要它，第二个参数是箭头内的文本。
