Okay, I got an div#outer with a width of 200px e.g.
In this div is another wider div, which has a width of 1200px.
To keep it simple this values are fix, in real this will be calculated.
The outer div has "overflow:scroll" so the user can scroll from left to right.
On init the inner div scrolls to a specific position.
This all works good, but why not in IE9 ?
I've made a fiddle, eventually someone has an idea whats going on in IE there.
var scrollOffset = parseInt(1255.3453 - 422.3453);
$('#outer').animate({
scrollLeft: scrollOffset
}, 250, function() {
// animation is over
// createChartNavi();
});
