type type TQCSeries=class(TLineSeries);

Quality Control Chart (QCC).

The TQCSeries can be used to plot Quality Control Charts (variable and attribute charts). It inherits all TLineSeries properties/methods and introduces some new properties. <Example> <code lang="Delphi"> var center, upcl, lowcl: double; Data: Matrix; EWMAResult: Vector; begin Data.LoadFromFile('ewma_data.mtx'); // EWMA with r= 0.37 EWMAChart(Data,DrawVec,center,upcl,lowcl,0.37,0.95); // setup TQCSeries Series1.CL := center; Series1.UCL := upcl; Series1.LCL := lowcl; Series1.ShowText := True; DrawValues(DrawVec,Series1); end; </code> <code lang="C++"> #include "MtxExpr.hpp" #include "Math387.hpp" #include "MtxVecTee.hpp" #include "StatSeries.hpp" void __fastcall WeibullPlot() { sVector ewmaresult; sMatrix Data; double center, upcl,lowcl; Data.LoadFromFile("ewma_data.mtx"); // EWMA with r= 0.37 EWMAChart(Data,ewmaresult,center,upcl,lowcl,0.37,0.95); // setup TQCSeries Series1->CL = center; Series1->UCL = upcl; Series1->LCL = lowcl; Series1->ShowText = true; DrawValues(ewmaresult,Series1,0,1,false); } </code> </Example>

Examples

delphi
var center, upcl, lowcl: double;
Data: Matrix;
EWMAResult: Vector;
begin
    Data.LoadFromFile('ewma_data.mtx');
    // EWMA with r= 0.37
    EWMAChart(Data,DrawVec,center,upcl,lowcl,0.37,0.95);
    // setup TQCSeries
    Series1.CL := center;
    Series1.UCL := upcl;
    Series1.LCL := lowcl;
    Series1.ShowText := True;
    DrawValues(DrawVec,Series1);
end;
