Hi Shweta,
The following code shows how to configure thechart for zooming and scrolling:
NCartesianChart chart =(NCartesianChart)nChartControl1.Charts[0];
chart.Axis(StandardAxis.PrimaryX).ScrollBar.Visible= true;
chart.Axis(StandardAxis.PrimaryY).ScrollBar.Visible= true;
chart.RangeSelections.Add(new NRangeSelection());
NPointSeries point = new NPointSeries();
point.Values.Add(10);
point.Values.Add(20);
point.Values.Add(30);
chart.Series.Add(point);
nChartControl1.Controller.Tools.Add(newNPanelSelectorTool());
nChartControl1.Controller.Tools.Add(newNAxisScrollTool());
nChartControl1.Controller.Tools.Add(newNDataZoomTool());
nChartControl1.Controller.Tools.Add(newNDataPanTool());
You can also take a look at the examples in the Interactivity / Tools section onhow to configure all the features in each tool individually.
