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.

I've changed it so they all use APS on the X axis, so it should be clearer now.

I like new charts better and they are easier to understand. Thanks.

They are some white space on left and right, but I think it is ok since presentation is clearer now.

There is amasing correlation between APS and Survival in roborumble scores :)

Would it be a good idea, to make survival difference green on bot comparison charts? This way color scheme matches the main chart.

Beaming (talk)15:26, 19 November 2013

Sorry to be such a pain. But I have one more thought. May be APS as X axis is not such a good choice. Since in meleerumble there is white spaces on left and right. No bots have APS above 70% and below 10%.

Would it be better to use rating? Or may be ANPP? Those take full scale.

Beaming (talk)03:00, 20 November 2013

I use APS because it is stable and always available. ANPP is sometimes not available (just after stabilising, before batches have run). I could use rating, but that I feel is too closely fit to which other bots are in the rumble at the time of viewing, and I would prefer the image to be more stable for long-term comparison.
