Is this some kind of joke? Man, I knew Pre-meds are borderline neurotic, but this takes the cake.
Pray, tell me what such a graph could tell you about a certain med school. Just a word of advice- don't put too much weight into these match results. As a matter of fact, don't put any weight into them. Chances are, 90% of you will change your chosen specialty 2-3 times during med school anyways, so choosing whatever school based on their numbers matching into Rad-Onc is unlikely to yield you any competitive advantage. Besides, many schools have unpredictable variations from year to year. My school, for example, had a 20% match rate into Peds this year. Why? Who the F knows. Anesthesia was less popular than before, blah blah blah. It really doesn't mean anything.
I can tell you that the prestige of a certain school is so low on the heirerarchy of what most residency programs look at to be almost negligible. Really want to take control of your future? Do well in school. Do well on the boards. Practice your interviewing techniques. Eliminate all perceptible character flaws. Buy a nice suit.
