ASP.NET MVC Charts & Graphs with Zoom & Pan

Download ASP.NET Chart Samples

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.
