I suggest that you take a look at our Data Zooming in which you will be able to see how the scaling progress through the zooming.
Open our Chart Explorer ( Start Menu -> All Programs -> Xceed Components -> Our components in action! -> Xceed Chart Explorer for .NET ), then go to All Examples -> Interactivity -> Data Zooming.
You can look at the code by clicking on the “C# Code” tab (you will find the complete source code of the explorer under -> C:\Program Files\Xceed Components\Xceed Chart for .NET and ASP.NET 4.1\Samples, or C:\Xceed Component Samples\Xceed Chart for .NET 4.1\Samples under Vista ).
