关键代码：

        /// <summary>        /// 设置X轴Title        /// </summary>        /// <param name="chart">ChartControl</param>        /// <param name="titleText">Title文字</param>        /// <param name="titleColor">Title文字颜色</param>        public static void SetAxisXTitle(this ChartControl chart, string titleText, Color titleColor)        {            XYDiagram _diagram = (XYDiagram)chart.Diagram;            if (_diagram != null)            {                _diagram.AxisX.Title.Visible = true;                _diagram.AxisX.Title.Alignment = StringAlignment.Center;                _diagram.AxisX.Title.Text = titleText;                _diagram.AxisX.Title.TextColor = titleColor;                _diagram.AxisX.Title.Antialiasing = true;                _diagram.AxisX.Title.Font = new Font("Tahoma", 14, FontStyle.Bold);            }        }        /// <summary>        /// 设置Y轴Title        /// </summary>        /// <param name="chart">ChartControl</param>        /// <param name="titleText">Title文字</param>        /// <param name="titleColor">Title文字颜色</param>        public static void SetAxisYTitle(this ChartControl chart, string titleText, Color titleColor)        {            XYDiagram _diagram = (XYDiagram)chart.Diagram;            if (_diagram != null)            {                _diagram.AxisY.Title.Visible = true;                _diagram.AxisY.Title.Alignment = StringAlignment.Center;                _diagram.AxisY.Title.Text = titleText;                _diagram.AxisY.Title.TextColor = titleColor;                _diagram.AxisY.Title.Antialiasing = true;                _diagram.AxisY.Title.Font = new Font("Tahoma", 14, FontStyle.Bold);            }        }

代码使用：

            chartControl1.SetAxisXTitle("时间x轴演示", Color.Red);            chartControl1.SetAxisYTitle("时间y轴演示", Color.Red);

运行效果：

chartControl
