Have you heard about Tufte's "small multiples" or Cleveland's "trellis"
displays? These approaches create a series of small plots instead of trying
to put everything into a single overly complex chart. I would stay away form
3D charts in Excel.
Trellis is a trademarked by Insightful software. I use the term "panel
charts" to reflect trellis and small multiple charts in Excel. I have
examples of horizontal and vertical panel charts at this link which may
help you see another way to visualize your data.

Jon Peltier has an example of stacked charts which is similar to my vertical
panel chart example.

Andy Pope has a two-way mini-plot example.

These should get you started.
