# Simple stair graph drawing in overleaf

I'm not really familiar with LaTeX (started working with it 2 days ago). Most of that work I'm doing in Overleaf, I only recently moved to graphs, could anyone possibly provide me a simple stair chart that I would be able to put in Overleaf and edit?

Example here: http://i.imgur.com/uDd02Nj.jpg

I found some example here: Tikzpicture: Step function (most minimalistic!)

But I'm having hard time with editing it.

Many thanks to anyone kind enough to help me!

EDIT: so far I have this code:

\usepackage{pst-all}
\begin{document}
\begin{pspicture}(-1,-1)(5,5)
\psaxes{->}(0,0)(-0.5,-0.5)(4.5,4.6)[$x$,0][$y$, 180]
\end{pspicture}
\vspace{1.6in}


and I want to make this out of it:

• Hi, welcome to TeX.SX! What do you want to change from the example you mention? (And which of the three answers were you specifically looking at?) – Torbjørn T. Jan 17 '17 at 12:14
• I was looking at the first one, but it's not quite it. So far I managed to do the axes and numbers in them using Overleaf: i.imgur.com/bdsfiIa.png Now I want to draw in it something like this: i.imgur.com/mEzvMUz.png So basically what I need right now is some hint on how to draw the mentioned line, thank you! – callmeadr Jan 17 '17 at 12:21
• Well, if you're using the code from the accepted answer there, you just need to change the coordinates used in the \addplot statement. – Torbjørn T. Jan 17 '17 at 12:30
• No, this is the code I'm using: \usepackage{pst-all} \begin{document} \begin{pspicture}(-1,-1)(5,5) \psaxes{->}(0,0)(-0.5,-0.5)(4.5,4.6)[$x$,0][$y$, 180] \end{pspicture} \vspace{1.6in} And it doesn't allow me to use \addplot in Overleaf for some reason – callmeadr Jan 17 '17 at 12:42
• No, it doesn't work because \addplot, which is defined by the pgfplots package, only works inside an axis environment, which must be inside a tikzpicture environment. Why can't you use the code from one of the answers to the question you referred to, and just change the coordinates? – Torbjørn T. Jan 17 '17 at 12:45

\documentclass{article}
\psaxes{->}(0,0)(-0.5,-0.5)(4.5,4.6)[$x$,0][$y$,180]
