Bubble chart ToolTip Script

[Prakash Bhai]

 Hi,

I have a price-cost having values(2 to 6).I want this column to show on bubble chart.when we directly used price-cost the bubble got overlapped so we used rand function to split values of price-cost(2.1,2.2,....,3.1,3.2,.....etc) but we r having issue when price-cost having value 2.6 to 2.9 etc.for these values the price-cost is showing as 3 in the ToolTip but we want the price-cost to show as 2 in the ToolTip.so pls any one can help with this issue.

Regards
Prakash
