I checked the "Wheel Zoom" check box in the "Data Zoom Tool" of the sample provided by your company and tried to operate the mouse wheel but it does not work. And I applied the following code to my source code, but it also does not work.
NDataTool dataZoomTool = new NDataZoomTool();
dataZoomTool.WheelZoomAtMouse = true;
dataZoomTool.BeginDragMouseCommand = new NMouseCommand(MouseAction.Wheel, MouseButton.Middle, 0);
nChartControl1.Controller.Tools.Add(dataZoomTool);
NDataTool dataZoomTool = new NDataZoomTool();
dataZoomTool.WheelZoomAtMouse = true;
dataZoomTool.BeginDragMouseCommand = new NMouseCommand(MouseAction.Wheel, MouseButton.Middle, 0);
nChartControl1.Controller.Tools.Add(dataZoomTool);
