Split Graphs

I'm pleased to announce that Righty/Lefty and Home/Away split graphs are now available for the 2002-2005 seasons. I've pulled two graphs that I thought illustrated their usefulness. The first graph here is Dontrelle Willis' strikeouts per 9 innings (K/9). Just look at how freakishly dominant he is against left-handed batters!

SK9

Then I pulled up Jeromy Burnitz's isolated power (ISO) home/away splits to take a look at how much better he was playing at Coors Field. Notice how his cumulative ISO with the Cubs was quite similar to his 2004 road stats.

These were two of the more obvious examples, but I hope you'll find these graphs are much easier to take a quick glance at than traditional split data. The other advantage of these graphs is you can see multiple season split data side-by-side. Enjoy and if you have any suggestions or notice any bugs you can discuss it in the forum or send a feedback form!
