Using this answer https://tex.stackexchange.com/a/113669/37570 I tried to apply the same setup to a graph, but it did not work with the center axis lines.
The first graph is set up as in the linked answer and the ticks are correct, but the X axis starts just before zero, which is wrong.
The second one is set up the way I need it to appear in the report but the ticks are wrong. What should I change to keep the layout of the axis but still have the APA ticks?
