three dimensionnal representation of data

Hello,

I've got three sources of data concerning a big group's profit margin. There are three product categories : men's clothes, women's clothes and children's clothes. To be more specific, I have three tables, each one displaying the profit margin for each product category depending on month and specific subsidiary (indeed this group owns several subsidiaries).
I would like to merge these three tables to have a three dimensionnal representation of the figures.

How can I do that?
