关键代码：

        /// <summary>
        /// 创建基准线ConstantLine
        /// </summary>
        /// <param name="chart">ChartControl</param>
        /// <param name="ctAxisValue">基准线数值</param>
        /// <param name="ctLegendText">基准线图例文字</param>
        /// <param name="ctTitle">基准线文字</param>
        /// <param name="ctTitleColor">基准线字体颜色</param>
        /// <param name="ctLineColor">基准线颜色</param>
        /// <param name="ctLineStyle">基准线样式</param>
        public static void CreateConstantLine(this ChartControl chart, int ctAxisValue, string ctLegendText, string ctTitle, Color ctTitleColor, Color ctLineColor, DashStyle ctLineStyle)
        {
            XYDiagram _diagram = (XYDiagram)chart.Diagram;
            if (_diagram != null)
            {
                ConstantLine _ctLine = new ConstantLine();

                _ctLine.AxisValue = ctAxisValue;
                _ctLine.Visible = true;
                _ctLine.ShowInLegend = true;
                _ctLine.LegendText = ctLegendText;
                _ctLine.ShowBehind = false;

                _ctLine.Title.Visible = true;
                _ctLine.Title.Text = ctTitle;
                _ctLine.Title.TextColor = ctTitleColor;
                _ctLine.Title.Antialiasing = false;
                _ctLine.Title.Font = new Font("Tahoma", 14, FontStyle.Bold);
                _ctLine.Title.ShowBelowLine = true;
                _ctLine.Title.Alignment = ConstantLineTitleAlignment.Far;

                _ctLine.Color = ctLineColor;
                _ctLine.LineStyle.DashStyle = ctLineStyle;
                _ctLine.LineStyle.Thickness = 2;

                _diagram.AxisY.ConstantLines.Add(_ctLine);
            }
        }

代码使用：

chartControl1.CreateConstantLine(25, "理论利润", "理论利润", Color.Red, Color.Red, DashStyle.Dash);

运行效果：

希望有所帮助！谢谢！
