I wonder if you could you perform the same with pure d3 instead, using the mousewheel up and down event?
like in
.call(d3.behavior.zoom()
.on("zoom", function() {
console.log("entering zoom function")
console.log("d3.event.sourceEvent.type: " + d3.event.sourceEvent.type); // we get a DOMMouseScroll
console.log("d3.event.sourceEvent.detail: " + d3.event.sourceEvent.detail);
if (d3.event.sourceEvent.detail > 0)
{
... augment the value
}else{
... decrease the value;
}
}
