Custom tooltip data

[Fabian Languy]

Hello,

thanks for this great jquery tool.

I would like to know if it's possible to add custom data, such as 

<span class="inlinebar">{1;John},{3;Mary},{4;Steve},{5;bob},{3;Edward},{5;Chen}</span>

SO that, when we put or cursor on the data, we can see the associate name to the value.

Thanks so much,

Fabian
