As you could notice there are some changes in rating graph.
For example with prompting on a point of a competition it is possible to see a place occupied with the participant, rating change and we can go to the table of results.
And what else do you want to see in that graph? :)
UPD: As for me...
1) Rank: 91 of 521
2) Solved: 2 of 5
3) Maybe somethink like http://codeforces.ru/contest/13/standings?place=91 or/and http://codeforces.ru/contest/33/standings?room=12
