the databook 2 has a whole bunch of information on the characters that i only wish I could be able to read, most importantly it has the "power/ability charts"

You know the big circle indicating the strengths of the characters.

what exactly do they mean? i want to be able to tell what's what to have an idea of how they compare.

The 3rd Hokage's data kind of disappointed me, he has the whole right side of the circle full which is impressive but why is he missing so much on the left? what the heck are the left side things?
for those interested, you can check out the character data's here
