yes, exactly. > In that case, the answer is: pgfplots uses the loglog coordinate system > as expected, but it rescales the unit vectors in order to a) fit the > axis into the prescribed dimensions and b) to view a "good" portion of > the axis.

Thank you for your explanations. Well in my case it's not really a big problem, I just have to play a little with axis limits to get what I want. Actually I thought that "after end axis" would be completely independent from the axis environment parameters (axis limits, etc.) while still allowing access to (axis cs:x,y) coordinates in order to put annotations on top of existing graph. However it appears it doesn't work that way... > Concerning the placement: it seems to me that the placement is correct. yes, the placement is fine. > The unit "0.25" and the coordinate "(0,-0.25)" are expressed in the > completely scaled pgfplots system which means that their meaning is a > little bit unclear. hmm, thanks I'll look into it.
