        {
            chartControl.Titles.Clear();                    //先清除以前的标题

            //横标题设置
            ChartTitle titles = new ChartTitle();            //声明标题

            titles.Text = HTitle;                            //名称
            titles.TextColor = System.Drawing.Color.Yellow;   //颜色
            titles.Indent = ;                                //设置距离  值越小柱状图就越大
            titles.Font = new Font("Tahoma", , FontStyle.Bold);            //设置字体
            titles.Dock = ChartTitleDockStyle.Top;           //设置对齐方式
            titles.Indent = ;
            titles.Alignment = StringAlignment.Center;       //居中对齐
            chartControl.Titles.Add(titles);                 //添加标题
