You need to add a new handler, _move
. Since the behavior of _mouse
is for click events.
.bind("mousemove", function (e) {
e.preventDefault();
s._xy()._move(e);
})
this._move = function (e) {
var v = s.xy2val(e.pageX, e.pageY);
if (v == s.cv)
return;
if (s.cH && (s.cH(v) === false))
return;
s.change(v);
s._draw();
};
