transparent chart

is there a way to make the chart background be transparent in Excel 2007?

That is, I want to be able to see cells behind a chart or put to charts one on top of another and have both of them show up instead of the top plot area block the apearance of the bottom chart?

Thanks!

I suppose it works the same way in Excel 2007 as in Excel 2003.
1. Rightclick on the Chart Area.
2. Select Format Chart Area... and Select Tab: Patterns
3. Set the Area: None
Done
