Can't display wins / losses in a line chart (Baseball)

[DavidJ726]

I'm trying to See if there's a trend with the KC Royals, it seems they start off every year on a high note, and then start loosing more and games as the season progresses. I've downloaded the past 4 years of data, but am having difficulty with a line chart. How should I arrange the data? I'm thinking of seperate trend lines for wins & losses, per year, or perhaps unique charts for wins and losses.

Go Royals!

Thanks!
David

Attach your data, without your data I'd suggest to group your dates by weeks, and count the # of wins per week. Are there weeks where they play more? You could add a calculated field that shows win % for the week win/total games.
