# how to draw discrete time diagram in tikz [closed]

Could anyone help me to draw the following in tikz?

1. A straight line.
2. On the line segment, I need to point out 0,1,2, \dots, k, k+1 in equal distance.
3. Between 0 and 1 and in general k, k+1 segment, I need to highlight, 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}

• @Markov The sticks are controlled by the loop \foreach \t in {1,2,\tmax}. If you change it to \foreach \t in {1,2,...,\tmax} then it draws all of them. I added such a possibility. I do not know what the typical ranges of \k and \t are, but I hope this gives you reasonable results in your use-case examples. – user121799 Mar 16 '19 at 14:03
