Extremely, Sorry about the vertical upload or the capture of the scale, Could you please consider the picture as horizontal, I need to draw this, I am able to learn from here the following: But I need to re-draw this in my current situation: Will be grateful for the help. Between 1 and k, dot dot will be fine instead of small line segments which I have drawn for P or 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)
node[above] {$\ifnum\t=\tmax
t\else\ifnum\t<4
\t\else .\fi\fi$} ;}
\fi}
\end{tikzpicture}
\end{document}
I also learned these today:
\begin{tikzpicture}[xscale=8]
\draw[-][draw=red, very thick] (0,0) -- (.5,0);
\draw[-][draw=green, very thick] (.5,0) -- (1,0);
\draw [thick] (0,-.1) node[below]{0} -- (0,0.1);
\draw [thick] (0.5,-.1) node[below]{$a=b=1/2$} -- (0.5,0.1);
\draw [thick] (1,-.1) node[below]{1} -- (1,0.1);
\end{tikzpicture}
\draw[-][draw=red, very thick] (0,0) -- (.5,0);
\draw[-][draw=green, very thick] (.5,0) -- (1,0);
\draw [thick] (0,-.1) node[below]{0} -- (0,0.1);
0
\draw [thick] (0.5,-.1) node[below]{$a=b=1/2$} -- (0.5,0.1);
0 a = b = 1/2
\draw [thick] (1,-.1) node[below]{1} -- (1,0.1);
