Hi Sweta,
The control does not have touch support for interactivity operations yet. You generally have to implement custom zooming in response to touch events.

Hi Shweta, The following code shows how to zoom in to a specified range on a particular axis: NChart chart = nChartControl1.Charts[0]; NBarSeries bar = new NBarSeries(); chart.Series.Add(bar); bar.DataLabelStyle.Visible = false; bar.Values.Add(10); bar.Values.Add(20); bar.Values.Add(30); // make sure all internal values are updated nChartControl1.RecalcLayout(); // zoom in NNumericAxisPagingView view = new NNumericAxisPagingView(); chart.Axis(StandardAxis.PrimaryX).PagingView = view; view.ZoomIn(new NRange1DD(0.5, 1.5), 0); Zooming this way (instead of using the NRangeAxisView) ensures you can also activate scrolling/panning later. We hope this helps - let us know if you have any questions.
