有人能帮我在 tikz 中画出下面的内容吗?
- 一条直线。
- 在线段上,我需要指出 0,1,2
\dots
,,钾,钾等距离+1。 - 在0和1之间以及一般的k、k+1段中,我需要突出显示,1,2,3,
\dots
,t。

\documentclass[tikz,border=3.14mm]{standalone}
\begin{document}
\begin{tikzpicture}
\pgfmathtruncatemacro{\L}{10} %<- length of the line
\pgfmathtruncatemacro{\kmax}{6}
\pgfmathtruncatemacro{\tmax}{7}
\draw (0,0) -- (\L,0);
\foreach \k in {0,...,\kmax}
{\draw (\L*\k/\kmax,0.2) -- (\L*\k/\kmax,-0.2) \ifnum\k<2 node[below,text
height=1.5ex]{$\k$}\fi
\ifnum\k=\numexpr\kmax-1 node[below,text
height=1.5ex]{$k$}\fi
\ifnum\k=\kmax node[below,text
height=1.5ex]{$k+1$}\fi;
\ifnum\k<\kmax
\foreach \t in {1,2,\tmax}
{\draw ({\L*\k/\kmax+\L*(\t/(\tmax+1))/\kmax},0.1)
-- ({\L*\k/\kmax+\L*(\t/(\tmax+1))/\kmax},-0.1);}
\fi}
\end{tikzpicture}
\end{document}
或者
