StatControlCharts.QCPChart Function

In this case each sample can have different size. You must store sizes in SampleSize vector.

Pascal

procedure QCPChart(const Data: TVec; const SampleSize: TVec; const DrawVec: TVec; out CL: double; const UCL: TVec; const LCL: TVec; Confidence: double = 0.997); overload;

Parameters

Parameters	Description
Data	Data to be analyzed. Each value represents number of defects.
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.
Confidence	Confidence level for upper and lower control limit. Confidence must lie in the (0,1) interval.

Description

An exeption is raised if Data and SampleSize length do not match.

Example

The following code will create P chart:

Uses StatControlCharts, MtxExp, Math387, MtxVecTee, StatSeries;
procedure Example(Series1: TQCSeries);
var CL, UCL, LCL : double;
  Data: Matrix;
  DrawVec: Vector;
begin
  Data.LoadFromFile('data.mtx');
  QCPChart(Data,10, DrawVec,CL,UCL,LCL,0.05);
  // setup limit lines
  Series1.UCL := UCL;
  Series1.LCL := LCL;
  Series1.CL := CL;
  // now draw actual data
  DrawValues(DrawVec,Series1);
end;

#include "StatSeries.hpp"
#include "MtxVecTee.hpp"
#include "MtxExpr.hpp"
#include "StatControlCharts.hpp"
#include "Math387.hpp"
void __fastcall Example(TQCSeries* Series1)
{
  sVector DrawVec;
    sVector Data;
  double cl,lcl,ucl;

  QCPChart(Data,10, DrawVec,cl,ucl,lcl,0.05);
  // Setup series properties
  Series1->UCL = ucl;
  Series1->LCL = lcl;
  Series1->CL = cl;
  DrawValues(DrawVec,Series1,0,1,false);
}
