Low non-showdown winnings

Hi everyone. As posted in my brags and beats thread my graph over a few thousand hands looks like a cone meaning high showdown winnings my c-won in the middle and my non showdown winnings line falling like crazy.
The more i play the more it looks like a slope to hell. Im not passive cause i double barrel in known situations and my AF is 2.1. So whats happenning? Im i doing something wrong?

Dw its normal.

You make money at the micros by having the best hand at showdown so ye it's normal that your non SD winnings are negative - you're probably making good folds when you think you're beaten and not bluffing too much --> negative redline.

just looking around a bit i found this :

"The red line is affected whenever you win or lose a pot without getting to showdown.

• Every time you fold before showdown your red line goes down.
• Every time you bet and make your opponent fold before showdown your red line goes up."

you can read the rest here, no idea how old this is, but may be helpful - http://www.thepokerbank.com/articles/software/red-line/
Also, 2.1 AF is not all that aggressive. still a bit on the passive side of things. Leakbuster for instance gives a recommended range of 2.3 - 4.1, but i'm not sure of your sample size, and it may even out.
