Creating a Gaussian Curve

A Gaussian or normal curve is used to show a distribution of probability over the values of a random variable.

To create a Gaussian Curve in C1Chart, use the following code:

// create and add to the chart data series representing Gaussian function
  //   y(x) = a * exp( -(x-b)*(x-b) / (2*c*c))
  // in the interval from x1 to x2
    void CreateGaussian(double x1, double x2, double a, double b, double c)
  {
    // number of points
      int cnt = 200;       var xvals = new double[cnt];
    var yvals = new double[cnt];
    double dx = (x2 - x1) / (cnt-1);
    for (int i = 0; i < cnt; i++)
    {
      var x = x1 + dx * i;
      xvals[i] = x;
      x =  (x - b) / c;
      yvals[i] = a * Math.Exp(-0.5*x*x);
    }
    var ds = new XYDataSeries()
    {
      XValuesSource = xvals,
      ValuesSource = yvals,
      ChartType = ChartType.Line
    };
    chart.Data.Children.Add(ds);
  }
