Free disk space chart in Excel

[Edi]

I would like to do a graph with following data in Excel:

Drive Date Used Space (Gb) Free Space (Gb)
C: 29/08/2005 2,5 5,5
C: 30/08/2005 3 5
D: 29/08/2005 7 3
D: 30/08/2005 5 5


The graph should be a stacked bar containing "Used Space" and
"Free Space". X-axis should be the date and Y-Axis the size while
Z-axis should contain the drive letter.

Is it possible to do that in Excel and when yes how?

Send examples or sheets to (e-mail address removed)

Thanks a lot.
