Content has multiple inner Divs with their own dynamic width

[agilist-github]

I have to fill up the contents dynamically with ajax so I changed it a little bit like below. Actually this is a chart which I want to auto scroll.
ScrollingChart_Marquee.pdf

$('.scroll-x').bind('finished', function () {
$(this).marquee('destroy');
}).marquee({
duration: 30000,
gap: 10,
delayBeforeStart: 1000,
//duplicated: true,
startVisible: true,
direction: "left",

            pauseOnHover: true,
            pauseOnCycle: true
        });

And start working when the content is loaded fully.
Next I am facing that inner divs get a width setting as style="width:100000px" which disturbs the whole inner content. Then I used the following code which gets my chart divs proper.
var myElements = document.querySelectorAll(".scroll-x");
for (var i = 0; i < myElements.length; i++) {
myElements[i].children[0].style.removeProperty('width');
}
But the problem comes when the scroll is reaching to end, it does not rotate the content but stretch the content and right portion gets stucked to right side only.
