}仅针对x轴（y轴同理）
chartArea1.CursorX.IsUserEnabled = true; chartArea1.CursorX.IsUserSelectionEnabled = true;
chart1.ChartAreas[0].AxisX.ScaleView.ZoomReset();
ZoomReset(0); —— 撤销所有放大动作ZoomReset(1); —— 撤销上一次放大动作设置滚动条宽度

以上所有方法也可以在chart属性里直接进行设置
获取选区坐标
Console.WriteLine(chart1.ChartAreas[0].AxisX.ScaleView.ViewMinimum);//当前显示范围最小坐标 Console.WriteLine(chart1.ChartAreas[0].AxisX.ScaleView.ViewMaximum);//当前显示范围最大坐标
