You really need to include three screenshots - the Battery view (which you included), the Screen On details (press the Screen item) and the History details (press the graph at the top of the main view).
It's pretty normal for the battery to drop a couple of percent right after disconnecting the charger - the battery is seldom actually full, but starts to discharge once it reaches 100%, and then the trickle charger starts to bump it back up, so depending on where it was at when you unplugged it you'll see some variation.
And frankly I don't see anything wrong with your battery data - you got about 24 hours and still have 46% remaining. The rest of the screenshots will help to paint a clearer picture.
