给X轴添加滚动条，放大X轴Y轴

见Dundas自带的Chart Features->Axis->Scrolling and zooming示例，

首先引用下面语句

using Dundas.Charting.WebControl;
...
若在自己的代码中若是单击按钮后显示图表，则将里面的代码写到按钮事件中
private void Page_Load(object sender, System.EventArgs e)
{

    // scrolling and zooming will force keeping of series data between callbacks.
    this.Chart1.ChartAreas["Default"].CursorX.UserEnabled = true;

    // Set restriction on how far the user can zoom in
    this.Chart1.ChartAreas["Default"].AxisX.View.MinSize = 5;
    
    // Check AJAXZoomEnabled property.
    if (CheckBoxAJAXZoomEnabled.Checked)
    {
        Chart1.AJAXZoomEnabled = true;
    }
    else
    {
        Chart1.AJAXZoomEnabled = false;
    }
    
    if (!this.Page.IsPostBack)
    {
        // Set initial X axis zooming
        this.Chart1.ChartAreas["Default"].AxisX.View.Position = 10.0;
        this.Chart1.ChartAreas["Default"].AxisX.View.Size = 25.0;
        
        // populate data here...
    
    }
}
...
