ASP.NET MVC Charts & Graphs with Zoom & Pan

Zooming and Panning allows analysis of data at microscopic level and is very useful while plotting graphs with large data sets. All Charts with axis support Zooming & Panning along both X & Y axes in CanvasJS. Given example demonstrates a Line Chart with Zoom / Pan feature. It also includes source code that you can try running locally.
