I imported XML data from the MLB's site and made a scatter plot. The
data however doesn't match up with other pics. Seems like its fliped
of rotated. Also, How can i plot a pitch location. I have the
coordantes but its to find where the strikezone should be.
thanks for anyhelp
 
This is interesting. I've watched the gameday (and the ESPN equivalent) on
the internet, and it's interesting to see the data stream.

I separated the pitches into three categories (three series): balls, called
strikes, and swings. The series are somewhat grouped together, but not in
any pattern I could discern. Nothing resembling a strike zone.

I'm not sure what the measurements are, either. X ranges from 59 to 122. If
those are inches, then it's 5 to 10 feet; if centimeters, then it's 2 to 4
feet, which might be reasonable. Y ranges from 90 to 175, which if that's
inches relates to 7.5 to 14.5 feet, or if it's cm it's 3 to 5.75 feet,
reasonable though the lower end is high.

I think you're going to have to do a bit of research. Go to Google or to the
GameDay blogs, or contact the writers at The Hardball Times, and see how
they translate these numbers into pitch locations. Good luck, it looks like
fun.

I've tried contacting but no one responded. Thanks I look at the site.
btw- X and y go from 0 to 250
 
That link discusses what X and Y are, and I suspect it's X and Y in the
"old" game day system, so it's not in inches, feet, cm, or any other system
an outsider would be familiar with. The newer ("enhanced") game day system
includes more info on each pitch, like velocity and position when it leaves
the pitcher's hand and when it crosses the plate, and more. The XML files
you referenced did not have this extra information.
