Multiple Stacked Graph with three dimensions

I have a dataset that I need to represent visually. It has three axes - State (X), Tons (Y), and Year (Z). The Tons are split into Imports, Exports, and Internal. In Excel I am able to show the data along all three axes but have to create separate graphs for Imports, Exports, and Internal. What I want to show is the Imports, Exports and Internal stacked together along along the three dimensions.

I am sharing a .pdf which shows the dataset, the separate graphs by Imports, Exports, and Internal and my desired output. Link to the PDF: http://bit.ly/nvgv4j

I want to avoid creating it outside a graphing/data program as I want to have flexibility to change th开发者_StackOverflow中文版e graph as the data changes. R or Excel works for me.
