sharepoint development

[meetmeat10pm]

Hello All,
Is there any experienced sharepoint developer or designer in this forum, i have a problme, which i wanted to discuss with,

if any one have any idea please advice me

I have a few data metrics for which there are diferent owners, now i want to creat a excel sheet with different tabs for different data so that when ever the owner of the metrics updates the excel sheet, the graphs will be updated on the share point, I wanted to know if this is feasible and if yes how is it possible.

Thanks in advance
