I would like to draw the following graph:
without using any TikZ style library. I have tried putting
\phantom to make X and Y aligned, it did not work (don't know why). Additionally, putting multiple alignments
&& etc. doesn't work, although it alignes correctly, now graph spans the whole line, which makes it ugly. I would be grateful for a neat solution.
I don't want any libraries because I think of using this in Mathjax.
