+-   `cssClass` : the class to assign to the tooltip's HTML DIV element, defaulted to "flotTip"
 -   `content` : content of your tooltip, HTML tags are also allowed; use `%s` for series label, `%x` for X value, `%y` for Y value and `%p` for percentage value (useful with pie charts using flot.pie plugin)  
   With `%x`, `%y` and `%p` values you can also use `.precision`, for example `%x.2` means that value of X will be rounded to 2 digits after the decimal point.  
   If no precision or dateFormat is set then plugin uses tickFormatter to format values displayed on tooltip.  
   If you require even more control over how the tooltip is generated you can pass a callback `function(label, xval, yval, flotItem)` that must return a string with the format described.  
   The content callback function pass may also return a boolean value of false (or empty string) if the tooltip is to be hidden for the given data point.
