Need help to create a Bubble Chart with data labels

[#1]

Dear Friends,

I want to create a bubble chart. Please refer the sample attached.

I have a historical table which has last 10 years data. I would like to retrieve the top 10 performers (order by count) of each year with their contributions across the 12 months and show in a bubble chart (like the sample attached).

I have a year’s listbox on the top. So, if I choose ‘2011’ then the top performers of the year and their contributions for the 12 months should be displayed in a chart.

How can I do that? Please share your valuable suggestions.

Thanks,

Muru

I want to represent the count visually with the bubble sizes. That's the reason I've chosen bubble chart.
