It seems to have lost labels on the left, though... and there is some 
oddness on the right edge, too, where the number "45" found in the other 
two plot versions has been replaced with "V. De Gen..." - what looks like 
part of someone's name or some other descriptor.  The "(1-3) 60%" under 
the PCA 5 Vars section also intersects with part of a plot.

Overall the effect is better, but the fine details could use some 
tweaking.
