Web Components Zoom Slider Overview

The Web Components ZoomSlider control provides zooming functionality to range-enabled controls. The ZoomSlider features a horizontal scroll bar, a thumbnail of the whole range, and a resizable zoom-range window. The ZoomSlider cannot work as a standalone control and it acts as an enhancement for range-based controls like the DataChart or CategoryChart.
