Various Beginner Questions

Hello all,

I was looking to post this under the "Absolute dumb newb questions" area but the Beginner forum seemed the best alternative.

1) when people post other people's stats, i.e. 26/5/3.2, what do each of these numbers refer to? I have pt, so I'm assuming its like VPIP/PFR/?
2) What program are people using when they post graphs of their winnings over the past 10k or 50k or 100k hands? Usually the y axis is BB. I tried looking for a feature on pokertracker that graphed your results, but I couldn't find one.
3) Is it worth spending time finding a juicy table if one is 6-8tabling at the 50nl games? and if so, does that mean waiting for a table that has a vpip above 25?

Sorry i didn't realize this, but i suppose most of my questions are related to pt

4) Why does my pahud label some opponents with icons (mouse, rock, etc.) but not others? Is it based on the # of hands i have played with them?

Thats all I can think of for now,

Grant
