Custom tooltip templates

[aureustaurus]

Hi. I try to add custom template and have fail. When i try to apply standard simple or simple static template all fine. But if I need template like this: 'The customer with ID: '+x+' has '+y+' % stocks'.
I can't do it because function which return template have no one arguments...
Maybe does it have some way to give point from "data: statsChartData" to "setTooltipsTemplate" functions? It very important to use this components.
Thanks.
