| Do you want to add fixed limit lines, like specification limits, to the chart; or are you looking to add a variable line, like the x-bar line of the primary chart? You can do the former, but not the latter. |

I am looking to add
- Upper and Lower Specification line
- +/-3 Sigma line
to the existing Control Chart during loading.

You can set the +- 3-sigma limits using code similar to
// Setup upper and lower 3-sigma limits values
this.PrimaryChart.GetControlLimitData(SPCChartObjects.SPC_LOWER_CONTROL_LIMIT).LimitValue = 20;
this.PrimaryChart.GetControlLimitData(SPCChartObjects.SPC_UPPER_CONTROL_LIMIT).LimitValue = 34;
You can add spec limits using code similar to:
// You must add a reference (using xxxx) System.Drawing.Drawing2D at the top of your module to resolve the DashStyle.Dash constant.
// Adding a Specification limit in addition to regular SPC control limits
SPCControlLimitRecord lcl2 = new SPCControlLimitRecord(this.ChartData,
SPCControlLimitRecord.SPC_LOWERTHAN_LIMIT, 0, "L SPEC", "L SPEC");
this.PrimaryChart.AddAdditionalControlLimit(lcl2, SPCChartObjects.SPC_MEASURED_VARIABLE, 1);
lcl2.ControlLimitValue = 26;
this.PrimaryChart.GetControlLimitData(SPCChartObjects.SPC_LOWER_CONTROL_LIMIT_2).LinePlot.LineColor = Color.Green;
this.PrimaryChart.GetControlLimitData(SPCChartObjects.SPC_LOWER_CONTROL_LIMIT_2).LinePlot.LineStyle = DashStyle.Dash;
SPCControlLimitRecord ucl2 = new SPCControlLimitRecord(this.ChartData,
SPCControlLimitRecord.SPC_GREATERTHAN_LIMIT, 0, "H SPEC", "H SPEC");
this.PrimaryChart.AddAdditionalControlLimit(ucl2, SPCChartObjects.SPC_MEASURED_VARIABLE, 1);
ucl2.ControlLimitValue = 32;
this.PrimaryChart.GetControlLimitData(SPCChartObjects.SPC_UPPER_CONTROL_LIMIT_2).LinePlot.LineColor = Color.Yellow;
this.PrimaryChart.GetControlLimitData(SPCChartObjects.SPC_UPPER_CONTROL_LIMIT_2).LinePlot.LineStyle = DashStyle.Dash;
