One thing I really missed from the old rumble was the LRP, but without ELO/Glicko we can't really do the whole straight-line fit any more. So, instead I have added a Score Distribution image on every bot's details page. The red is APS and the green is Survival (as seen in image the mouseover). The image is directly embedded in the HTML using data URIs, so if you are using IE, 8 and later only, otherwise pretty much everything supports it. I'm also planning to add this to the BotCompare page so you can analyse differences in score compared to opponent score for both APS and survival.
Ahhh, neat stuff. That's very nifty with directly embedding the image data there. For some reason the image is displaying very tiny for me though under Firefox 20.0. It gets scaled to the box around it properly under Chromium, but not Firefox.
EDIT: Nevermind... the styles.css file was being cached and that was the problem. A ctrl-r fixed it.
There is something fishy with a chart in the right part close to the end. If you look at above CunobelinDC score distribution you would see that there is no corresponding red points for stronger opponents, while blue and grean are there. This is quite common theme for other bots as well.
Also have a look at this EvBot score distribution you would see the problem with normalizing, i.e. about 1/4 of the space in the right part of the chart has no points. Which is non optimal use of the chart space.
Is it still showing the problem? I don't see anything wrong right now. I had some issues with (I suspect) bad bytecode and versioning, but that should be fixed now.
As for the EvBot chart, that is because in meleerumble nobody gets higher than ~75%, so the top 25% is empty. Although I guess I could normalise to the top score, I'd rather have the charts consistent as better bots are released.
Aha, I see now why melee charts were somewhat off.
But I insist that I do not see red points for X>95% for CunobelinDC. Look at 5 the rightmost green points, I cannot locate red (APS) or blue for the same X values. It might be aliasing problem or may be points are just on top of each other.
Green is survival, and so the X value is the average survival score of the enemy bot. The red and blue use enemy APS as the X value, not survival, and since survival scores are higher the green dots go further to the right.
I've actually thought about changing the X axis to just be enemy APS to make it easier to interpret. Or ordering the X-axis by rank instead of using APS values.
