如何将此年度时间表转换为半年时间表？

使用此代码，

\begin{tikzpicture}
  \draw[line width=1pt] (0,0) -- (12,0)node[right=4mm]{(periods)};
  \foreach \x/\y in {18000/0,19080/1,20224.80/2,21438.29/3}%
  {
  \draw[line width=1pt] (4*\y,-2mm) node[below] {\y} -- ++(0,4mm) node[above] {\$ \num{\x}};
  }
  \draw[-latex] (2,-7mm) -- +(0,-10mm)node[below]{\$ \textbf{18,000}*0.06 = \$1,080};
  \draw[-latex] (6,-7mm) -- +(0,-20mm)node[below]{\$ \textbf{19,080}*0.06 = \$1,144.80};
  \draw[-latex] (10,-7mm) -- +(0,-10mm)node[below]{\$ \textbf{20224.80}*0.06 = \$1,213.49};
\end{tikzpicture}

我有以下时间表： 在此处输入图片描述

但是，我想将这个年度复利转换为半年复利，总共收取 6 个利息，分别在 0 和 1/2、1/2 和 1、...、2 1/2 和 3 之间，通过将每个部分分成两部分显示在线下。我仍然希望在每年年底显示金额，因此时间线上方的金额应为：$18,000、$19,096.20、$20,259.16、$21,492.94。

我怎样才能获得这样的一条线？

最好将利息对齐到左侧，如图所示，这样看起来更整洁——现在只需在左侧交叉即可添加季度利息

\documentclass[tikz, margin=3mm]{standalone}
\usepackage{siunitx}
\usetikzlibrary{positioning,calc}
\begin{document}
\begin{tikzpicture}
  \draw[line width=1pt] (0,0)node(a){} -- (12,0)node(b){}[right=4mm];
  \foreach \x/\y in {18000/0,19000/1,20000/2,21000/3}%
{
\draw[line width=1pt] (4*\y,-2mm) node[below] {\y} -- ++(0,4mm) node[above] {\$ \num{\x}};
\node [draw]at(-0.5cm,-2cm)(p){\$ {18,000}*0.06 = \$1,080};
\node [draw,below=of p.west,anchor=west](q){\$ {19,080}*0.06 = \$1,144.80};
\node [draw,below=of q.west,anchor=west](r){\$ {20224.80}*0.06 = \$1,213.49};

\draw[-latex] ($(a)!0.16!(b)$)node[below,yshift=-12pt,fill=white]{0.5} |-(p);
\draw[-latex] ($(a)!0.48!(b)$)node[below,yshift=-12pt,fill=white]{1.5} |-(q);
\draw[-latex] ($(a)!0.84!(b)$)node[below,yshift=-12pt,fill=white]{2.5} |-(r);
}
\end{tikzpicture}
\end{document}
