PokerEV: I know I ran bad today but how much??

[RiverRider]

I know I ran bad today, but I have some difficulties interprating my PokerEV graphs.

Lets say that:
<u>Game Analysis Graph</u>
Showdown winnings = $200
Slansky Bucks = $2000
Total Winnings = -$600

<u>Luck Graph</u>
All in winnings = $500
Expected All in winnings = $1200

So does it mean that I lost $2600 in equity today (Slansky Bucks - Total Winnings)? How reliable are those stats?
