This figure is made with Tikz package, I need suggestions to make font more bigger and more readable. I tried many solutions such as \Large but still not able to increase the font more clear. My advisor told me to use the spaces in the image attached. Any suggestions to make the font more clear and bigger ??

  • Unfortunately your code won't compile. Apart from the fact that you include graphics that most likely none of the users has, you forgot to provide the definition of \point and the o-o style. BTW, if any of the answers you received so far helped you to solve your problems, could you perhaps consider accepting them? You could e.g. use \begin{tikzpicture}[o-o/.style={{Circle[open]}-{Circle[open]}}, every node/.append style={font=\LARGE}] and kick out all \Large commands to universally increase the size of the characters. – user121799 Dec 29 '18 at 4:21
  • The code is working on overleaf. May be because there are figures that is not included so you are not able to run it – Heba Mohsen Dec 29 '18 at 4:39
  • @marmot The code is working now. – Heba Mohsen Dec 29 '18 at 4:48

  • Your solution is new and I like it. But in the my original code, I was having a 2 nodes as in the following code. I tried to add them but it gives me errors: \node[right=10.6 of a,yellow!70!black, yshift=-.7cm,xshift=1.4cm] (b) {\Large\textcolor{black}{$H_1$}}; \node[right=8.3 of a] (b) (russell) at (4.1,0) {\includegraphics[width=1.4cm]{Figures/R}}; – Heba Mohsen Dec 29 '18 at 19:31
  • @HebaMohsen, do you refer to your mwe? such approach as you show in comment, is not present in my mwe ... note, my mwe is rewritten from scratch and replicate showed image. it hasn't anything common with your mwe (which code is almost not possible to understand). if you have new request, pleas ask new question that more member of site can help you. sorry, i do not understand your comment. – Zarko Dec 29 '18 at 19:38
  • Thanks. but you forget to add the two separated vertical lines in my mwe, (Please see the attached picture). I am trying to add them to your mwe but I am not able. Could you please help me as I am new to tkiz? – Heba Mohsen Dec 29 '18 at 19:47
  • @HebaMohsen, your image is not clear. i see there some lines on the left, but i assumed that they are some artifacts arisen at copy your image from your PC to here. can you explain where should be these lines, what they should connect? what is they purposes. they can be part of table, but note, the any widening of the table can cause that table will spill out of page ... – Zarko Dec 29 '18 at 19:58
  • I have updated the question with a clear image. The two lines represent a road of a car. The green line is the path of it. Your answer is great. what I need now, is just to add the lines to the your code. – Heba Mohsen Dec 29 '18 at 20:15
