StatControlCharts.QCSChart Method

S-Chart.

public QCSChart(TMtx Data, TVec DrawVec, ref double CL, ref double UCL, ref double LCL, double Confidence);

Parameters

Parameters	Description
Data	Each Data row contains replicated observation taken at specific time.
DrawVec	Returns values to be drawn.
CL	Returns control Chart centerline.
UCL	Returns control Chart upper control limit.
LCL	Returns control Chart lower control limit.
Confidence	Confidence level for upper and lower control limit. Confidence must lie in the (0,1) interval.

Remarks

Calculates S-Chart drawing values, center line, upper and lower control limit.

C# Example

Place a TChart component on the chart and add a TQCSerie (Series1). The following code creates necessary values for S chart:

using Dew.Math;
using Dew.Math.Units;
using Dew.Stats.Units;
namespace Dew.Examples
{
  private void Example()
  {
    double cl,ucl,lcl;
    Matrix Data = new Matrix(0);
    Vector DrawVec = new Vector(0);
    Data.LoadFromFile("data.mtx"); // data is now initialized
    StatControlCharts.QCSChart(Data,DrawVec,out cl, out ucl, out lcl, 0.025);
  }
}
