Generating, plotting, and analyzing the data

1. Double-click the button control to display the

Form1 code, with the

cursor inside the click event handler of the button control.

2. Add the following code to generate random data, plot the data,

calculate the mean of the data, and display the mean on the gauge.

[VB.NET]

' Declare and initialize an instance of WhiteNoiseSignal.

Dim whiteNoise As New WhiteNoiseSignal()

' Store the generated data in a double array named data.

Dim data As Double() = whiteNoise.Generate(1000.0, 256)

' Use the PlotY method to plot the data.

Plot.PlotY(data)

' Use the Mean method to calculate the mean of the data.

Dim mean As Double = Statistics.Mean(data)

' Display the mean on the gauge.

gauge.Value = mean

[C#]

// Declare and initialize an instance of WhiteNoiseSignal.

WhiteNoiseSignal whiteNoise = new WhiteNoiseSignal();

// Store the generated data in a double array named data.

double[] data = whiteNoise.Generate(1000.0, 256);

// Use the PlotY method to plot the data.

Plot.PlotY(data);

// Use the Mean method to calculate the mean of the data.

double mean = Statistics.Mean(data);

// Display the mean on the gauge.

gauge.Value = mean;
