Usage Example

This example shows the creation of a probability plot.

Create a new Weibull/ALTA Plot instance.

       Dim WeibullALTAPlot As New WAPlots

Declare a WeibullDataSet. See New WeibullDataSet for additional details.

       Dim WDS As New WeibullDataSet

Add values to the raw data. See AddFailure for additional details.

       WDS.AddFailure(1, 1)
       WDS.AddFailure(2, 1)
       WDS.AddFailure(3, 1)

Calculate the WeibullDataSet. See CalculateBestFit for additional details.

       WDS.Calculate

Add the WeibullDataSet to the WAPlots.

       WeibullALTAPlot.AddDataset(WDS)

Create the WAPlot. In this example, it will create a Probability plot.

       Dim FinalPlot As Bitmap = WeibullALTAPlot.CreatePlot(WAPlotType.Probability)
