RazorChartViewer works with the JsChartViewer Javascript control on the browser side to support advanced chart user interactions, such as programming track cursors, zooming and scrolling and AJAX chart updates. It provides chart information needed by the JsChartViewer, and handles the AJAX chart update requests and responses between the server and the browser.
