Can I make gray scale charts?

[Laurel]

I have a series of pie charts and bar charts. Is there anyway to get them
in black and white instead of color?

You can do it manually after the charte has been created. Right-click within
a data point area (pie slice for example) and choose to Format Data Point and
you can change the color.
Just remember that if the charts are very complex and have many pie
slices/bars, it's difficult for the human eye to distinguish between a lot of
shades of gray.
