![如何在乳胶中制作此图表](https://linux22.com/image/271931/%E5%A6%82%E4%BD%95%E5%9C%A8%E4%B9%B3%E8%83%B6%E4%B8%AD%E5%88%B6%E4%BD%9C%E6%AD%A4%E5%9B%BE%E8%A1%A8.png)
有人能用 LaTeX 画出这个图表吗?如果你有其他想法让它比我画的更好,我将不胜感激。以下是图 1 和图 2 的绘制方法
感谢 John Wickerson 先生为我提供了最佳的图表样式
如果可能的话用不同的风格发表评论谢谢
\usepackage{tikz}
\usetikzlibrary{arrows, decorations.markings}
% for double arrows a la chef
% adapt line thickness and line width, if needed
\tikzstyle{vecArrow} = [thick, decoration={markings,mark=at position
1 with {\arrow[semithick]{open triangle 60}}},
double distance=1.4pt, shorten >= 5.5pt,
preaction = {decorate},
postaction = {draw,line width=1.4pt, white,shorten >= 4.5pt}]
\tikzstyle{innerWhite} = [semithick, white,line width=1.4pt, shorten >= 4.5pt]
答案1
干得好。
