Declaration
Procedure QCUChart(Data: TVec; SampleSize: TVec; DrawVec: TVec; out CL: TSample; UCL, LCL: TVec; Confidence: TSample = 0.997);
| Parameter | Description |
|---|
| Data | Data to be analyzed. Each value represents number of defects. |
| Confidence | Confidence level for upper and lower control limit. Confidence must lie in the (0,1) interval. |
| Samplesize | Sample size. Can be integer or vector. |
| 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. |
