Report Assistance

Hello,

Hopefully one of you report guru's can assist me in creating the following chart in one of my reports.

I have an array that has 3 storage pools (all-ssd, all-fc and all-nl).  I would like to do a stacked column chart to show each pool (Free Space / Total Space) per pool

For Example

all-ssd [########################################-------------------]

all-fc    [###########-------------------------------------------------------------------]

all-nl    [###########################----------------------------------------]

Can anyone provide any assistance on how to do this?

Thanks!
