Michael-

You can actually do that today (though I think it's not as obvious as it could be):

1.In the Project palette pick the colors tab (the color wheel)
2. Click on the Alternate Rows color swatch, and pick a color (default is for it to be 100% transparent)

There is a drawback though: when you print the lines don't show up - the whole background of the chart shows up as the alternate color you've picked. At least it does for me in beta 10.
