You can take a look at the following example in our demo application: All Examples > Interactivity > Tools > Data Zoom Tool By default the chart in the example is 2D, but there is a setting to switch it to a 3D point chart. In general this method applies for all Cartesian series, including surface series. The same thing can be achieved programmatically. The code below demonstrates how to zoom-in on a portion of a mesh surface: nChartControl1.Controller.Tools.Add(new NSelectorTool()); nChartControl1.Controller.Tools.Add(new NTrackballTool()); NChart chart = nChartControl1.Charts[0]; chart.Enable3D = true; chart.Width = 50; chart.Depth = 50; chart.Height = 40; NMeshSurfaceSeries surface = new NMeshSurfaceSeries(); surface.Data.SetGridSize(10, 10); chart.Series.Add(surface); for (int i = 0; i < 10; i++) { for (int j = 0; j < 10; j++) { double y = Math.Sin(i * 0.3); double x = i; double z = j; surface.Data.SetValue(i, j, y, x, z); } } NAxis axisX = chart.Axis(StandardAxis.PrimaryX); axisX.ScaleConfigurator = new NLinearScaleConfigurator(); NNumericAxisPagingView pagingViewX = (NNumericAxisPagingView)axisX.PagingView; pagingViewX.Enabled = true; pagingViewX.Begin = 1; pagingViewX.Length = 2; NAxis axisZ = chart.Axis(StandardAxis.Depth); axisZ.ScaleConfigurator = new NLinearScaleConfigurator(); axisZ.Visible = true; NNumericAxisPagingView pagingViewZ = (NNumericAxisPagingView)axisZ.PagingView; pagingViewZ.Enabled = true; pagingViewZ.Begin = 1; pagingViewZ.Length = 2; Best Regards, Nevron Support Team
