number line help

Postby Phooey » Sun Sep 29, 2019 4:34 pm

Hi Guys,

I am brand new to this forum and LaTeX in general. But I have now been tasked with writing the assessment materials for my employer so decided LaTeX was the way to go.

So I need to create this diagram. Please, I have spent all weekend trying to make sense of the google results I get. Can someone please suggest a simple piece of code with some brief explanation as to what is happening.

It is just the number line with the arrow. I am ok with the text and formatting.

Please can you show us, what you already have tried. The figure is so simple, that you even could make it with the standard picture environment:
Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex})
  1. \documentclass{article}
  3. \begin{document}
  4. \setlength{\unitlength}{2mm}
  5. \begin{picture}(60,10)(0,-10)
  6. \put(0,0){\line(1,0){60}}%
  7. \multiput(0,0)(1,0){61}{\line(0,-1){1}}%
  8. \multiput(0,0)(5,0){13}{\line(0,-1){2}}%
  9. \put(0,-2.5){\makebox(0,0)[ct]{0}}%
  10. \put(10,-2.5){\makebox(0,0)[ct]{10}}%
  11. \put(20,-2.5){\makebox(0,0)[ct]{20}}%
  12. \put(30,-2.5){\makebox(0,0)[ct]{30}}%
  13. \put(40,-2.5){\makebox(0,0)[ct]{40}}%
  14. \put(50,-2.5){\makebox(0,0)[ct]{50}}%
  15. \put(60,-2.5){\makebox(0,0)[ct]{60}}%
  16. \put(37,-10){\vector(0,1){8}}%
  17. \end{picture}
  18. \end{document}

The picture environment that should be explained in every complete LaTeX introduction, so please read one. You won't become happy with latex only using google search instead of reading a good introduction.

However, I would recommend to use pgf/TikZ instead of picture even for simple figures. Because it would be a good choice to learn TikZ step by step.

That is absolutely perfect. Thank you so much.

I haven't saved anything that I have tried but essentially, I have tried drawing vertical and then horizontal lines and adding numbers - a complete mess!

I tried nodes but only managed to get a line with numbers and couldn't work out how to get the gradations.

I will look for a decent tikz tutorial book. I've managed to get some basics from YouTube vids but only managed to put together a simple document, a document that looks nice but very little in the way of graphics.

Oddly, I could managed to put together a calculus paper - my next job - but making 'pictures' isn't so easy.

Thank you again. I really appreciate you taking the time.

Edit: I will download the resource you suggested!
