Is there anyway that I can fill a bar/column chart with patterns as I can do
with Excel 2003?

I know that MicroSoft removed this feature in Excel 2007. But I don't
understand why they do it. Lots of academic journals prefers black and white
charts than shaded or charts with gradient. Also, it's hard to tell one
series of data from another series if they are printed in black and white.

Any help is appreciated.
