Description

The A property determines the value of the shape distribution parameter for a random value.

Comments

Property value must be greater than zero.

Example

To execute the example, the form must have the ChartBox component and the UiChart component which serves as the source for ChartBox.

Class OBJ18692Form: Form
    ChartBox1: ChartBox;
    UiChart1: UiChart;
    Weibull: SmWeibullDistribution;
    Values: Array Of Double;
    Const Cnt = 100;

    Sub OBJ18692FormOnCreate(Sender: Object; Args: IEventArgs);
    Begin
        Weibull := New SmWeibullDistribution.Create;
        Text := Weibull.DisplayName;
        Weibull.A := 3.2;
        Weibull.B := 0.8;
        Values := Weibull.RandomVector(Cnt);
        UiChart1.PointCount := cnt;
    End Sub OBJ18692FormOnCreate;

    Sub UiChart1OnGetDataValue(Sender: Object; Args: IUiChartGetDataValueEventArgs);
    Begin
        If Args.PointIndex < Cnt Then
            Args.Value := Values[Args.PointIndex];
            Args.Result := True;
        End If;
    End Sub UiChart1OnGetDataValue;
End Class OBJ18692Form;

Executing this example makes a Weibull distribution chart:
