  hello.
  
  I used flex chart on c1.
  
  I want to line color of NormalCurve but error occurs.
  
  can you help me?

  Dim histogramSeries = New C1.Win.Chart.Histogram()
      histogramSeries.Name = "Frequency"
      histogramSeries.Binding = "X"
  
      histogramSeries.NormalCurve.Visible = True
      histogramSeries.NormalCurve.LineStyle.FillColor = Color.Blue
      histogramSeries.NormalCurve.LineStyle.StrokeColor = Color.Blue
      Chart2.Series.Add(histogramSeries)

  Hi,

  The Style/LineStyle for a Series/HistogramSeries is null/Nothing by default. Therefore accessing a property (StrokeColor/FillColor) on a null object will throw NullReferenceException. Rather you should set the ChartStyle object for LineStyle as follows:

  histogramSeries.NormalCurve.LineStyle = New ChartStyle With {
      .StrokeColor = Color.Blue,
      .StrokeWidth = 2
  }
  

  Just for your information, since it’s a curve therefore setting FillColor will not make any difference.

  Regards,

  Basant
