InvientCharts : question about mouse events on iPad


I’m using InvientCharts to render a Pie Chart.

This Pie Chart has tooltips (when the user does a mouse over on a slice) and has a click event when clicking on a slice (to zoom on the datas of this slice)

On computer browsers, everything works well. The2 behaviours are correctly managed (mouse over and mouse click).

But on iPad, the mouse over and mouse click are the same event. When touching a slice, the tooltip is showed, and after the click event is managed. Why ?

In touch screen with jQuery, I tought that a mouse over event was translated in one click and a mouse click event in two clicks. Am I wrong ?

Is there a way to have this behaviour with InvientCharts ?

Kind regards,
