推荐答案

chartCoRel.Series.Add("TrendLine");
                    chartCoRel.Series["TrendLine"].ChartType = SeriesChartType.Line;
                    chartCoRel.Series["TrendLine"].BorderWidth = 3;
                    chartCoRel.Series["TrendLine"].Color = Color.Red;
                    // Line of best fit is linear
                    string typeRegression = "Linear";//"Exponential";//
                    // The number of days for Forecasting
                    string forecasting = "1";
                    // Show Error as a range chart.
                    string error = "false";
                    // Show Forecasting Error as a range chart.
                    string forecastingError = "false";
                    // Formula parameters
                    string parameters = typeRegression + '','' + forecasting + '','' + error + '','' + forecastingError;
                    chartCoRel.Series[0].Sort(PointSortOrder.Ascending, "X");
                    // Create Forecasting Series.
                    chartCoRel.DataManipulator.FinancialFormula(FinancialFormula.Forecasting, parameters, chartCoRel.Series[0], chartCoRel.Series["TrendLine"]);
