dataTipFunction is a property of the chart, not the series, so you will have to have a single function that looks at the hitData to determine which series the mouse is over. The hitData.element property will give you access to the properties of the series that the mouse is over. If you give the series ids, you can then have your datatip function call your series specific function based on the element id.
