Setting Wall Color in 3-D charts

[Marian]

When setting the wall color in a 3-D chart I have encountered a problem with
the side wall and floor. They appear to have a embedded shawdow set. Is
there anyway to remove the shadow so the walls and floor will all reflect the
same color as Excel 2003 allowed?

I don't believe you can change the side wall and floor colors. Would you
consider changing to a regular column chart instead? A normal column chart
might work better because it's generally thought that 3-D effects can
misrepresent the visual interpretation of the underlying data.
