Score Distribution

Can someone describe how to read the fancy new Score Distribution graph? What is the X axis? What is the Y axis? What do the different colored dots represent?

There is a caption under the diagram describing X and Y. Mouse over the image to see what the colors mean.

Basically X, opponent strength, Y is how good your robot is against that opponent.

Can I ask a question over here? If I look at my or at any "bot detail page" (like http://literumble.appspot.com/BotDetails?game=roborumble&name=mae.Mae1%201.1 ) I see many abbreviations ,for example APS,NPP and KNNPBI.Is there a page in this wiki or somewhere else where these words are explained ,because my English is not so good that I could deduce the meaning myself. Thank you very much.

Some of them are listed at LiteRumble.
The important one is APS, as that is the primary ranking. APS is average percentage score.
For each opponent your percent score is 100% * <your score> / (<your score> + <opponent score>). APS is this value averaged over all the battles/opponents for your bot, so it is important not just to win, but to win by the largest margin possible.
PWIN is percentage of wins.

I have added a page on the Literumble here (and a link to it from the main page) which provides better explanations of what the different scores are.

If you have any questions, or think that they need to be clarified, just ask.

Thank you very much.
