Hi all, This seems to be a truetype font issue my plots were made without true type support. I noticed the difference between Alan plots and mine were not only in position and orientation but also in fonts used. I have a lot of true types fonts installed but for strange reason none is selected. only with a package free-ttf-fonts they are selected. result in attach. the text orientation is corrected but not the vertical displacement.
