Hello,

I've got a basic column chart with vertical grid lines but no horizontal grid lines. On my category axis I have week ending dates. All I want to be able to do is stagger the background color between each day (between each major grid line) so that they alternate between gray and white (e.g. 1/8/11 white, 1/15/11 gray, 1/22/11 gray, etc.). I'm sure there has to be a fairly simple way to do this but I haven't been able to find it. Any ideas?

Thanks!
