I "draw" two pstricks pictures, one after the other. At the beginning of each of them, I specify the font size (\small in my example). Then I draw axes, with labelFontSize=\normalsize, which should result in the same \small size as the whole picture. I know that this is useless, but I just add it in the code in case I want to change it in the future. However, the font size of the labels are smaller in the first picture than in the second one. Does anyone know why?
I compile with TeXstudio, using XeLaTeX and the chain DVI->PS->PDF (but it does the same with LuaLaTeX, and I doubt that the vizualisation chain would change anything).
Here My code:
