I want to place a lot of pictures and plots in a long document. By now, I am using figure-environment with center-environment, but the tikz-axis-plots didn't align well with included eps-pictures or tikz-pictures. I read PGFplot to occupy full \linewidth, and aligned y=axis across tikzpicture and the pgfplot-Manual (regarding alignment), and found out, that I can use ylabel style={overlay} and yticklabel style={overlay}.
To be precise, the situation is better, but images are still not aligned well. I want the left and right border of the grid to be exacly above the other boxes. See my example for illustration.
Thanks in advance.
