If I read it correctly, there two lines have different parameters too:
xoffset=3, yoffset=2
xoffset=2, yoffset=3 .
How you set up offsets depends on the layout of your figures. I mean
portrait or landscape. You could find more on manual. I do agree with
you it takes some time to figure these things out and get a nice
figure.
