Display Charts on click like how it is in Picassa

Dear Friends,

I have an Excel Workbook with a worksheet containing around 5-6 charts placed side by side. When user clicks on any chart I want that particular chart to Zoom and come in the centre whereas the background must become inactive (Similar to how Picassa Photo Viewer works)..

If this is possible in MS Excel 2003 then nothing like it. If not, Can you please suggest some other platform where it is possible?

Regards,
Vaibhav
