The scrollbars that you see in the previously attached project are showd because a ChartPanZoomBehavior is present. If you remove this behavior you will not see the scrollbars.
Unfortunately we do not have a built-in feature for neither scroll-to-zoom nor drag-to-pan. We have plans to introduce this with the next Q2 official release (scheduled at the beginning of June). However, I have attached a simple project to demonstrate one possible way to achieve this functionality. Give it a try and see if you can apply this approach to your actual app.
