the green line is the total chips you have won/lost so you want that to go up obviously. if you get it all in preflop with AK against QQ and you win let's say $1000, your green line will go up by $1000.
however your expected value (EV) for the hand is only $439 because mathematically the probability of you winning the hand is 43.9% (0.439 * $1000 = $439).
the orange line is the total EV that you won. your green line is running above your orange line, which means that you've been running good
3500 hands isn't a very big sample and this deviation between your winnings and EV isn't unusual. but bear in mind that it works both ways and sometimes you'll lose more than expected, i.e. your green line will be lower than your EV line.
blue line is your winnings for all hands that went to showdown. this should definitely go up if you're doing it right
red line is non-showdown winnings. so these are pots you win when the other players fold. i dunno enough about what sngs you play etc to be able to say whether your slightly negative red line here is ok or not.
posting hands you're unsure about in the appropriate forum and looking at stats like vpip, pfr, cbet etc are going to be more useful for analysing your play than graphs though.
