/// <summary>
/// 创建Drill-Down样式的Title
/// </summary>
/// <param name="chart">ChartControl</param>
/// <param name="title">title文字</param>
/// <param name="visible">是否可见</param>
public static void AddDrillDownTitle(this ChartControl chart, string title, bool visible)
{
ChartTitle _chartTitle = new ChartTitle();
_chartTitle.Alignment = StringAlignment.Near;
_chartTitle.Antialiasing = false;
_chartTitle.Font = new Font("Tahoma", 10F, FontStyle.Underline);
_chartTitle.Indent = 20;
_chartTitle.Text = title;
_chartTitle.TextColor = Color.RoyalBlue;
_chartTitle.Visible = false;
chart.Titles.Add(_chartTitle);
}
