Using a CustomControl to Create Chart Control

In Microsoft Visual Studio 2022 (version 17.0 or above), create a Windows Forms App (.NET Framework) project and in Project > Add New Item.., select ActiveReports 19 Code-Based Report template and click Add.
Add reference to System.Windows.Forms.DataVisualization.
From the Visual Studio toolbox, drag and drop the Data > Chart item to the design surface.

Add the following code to the code-based report constructor after the InitializeComponent method:

Dim chart = CType(Me.customControl1.Control, System.Windows.Forms.DataVisualization.Charting.Chart)
Dim chartArea = New System.Windows.Forms.DataVisualization.Charting.ChartArea("Main")
chart.ChartAreas.Add(chartArea)
Dim seriesColumns = New System.Windows.Forms.DataVisualization.Charting.Series("Columns")
For Each val In New Single() {6, 14, 3, 4, 2, 2, 1, 3}
    seriesColumns.Points.Add(Convert.ToDouble(val))
Next
seriesColumns.ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Radar
chart.Series.Add(seriesColumns)

var chart = (System.Windows.Forms.DataVisualization.Charting.Chart)this.customControl1.Control;
var chartArea = new System.Windows.Forms.DataVisualization.Charting.ChartArea("Main"); 

chart.ChartAreas.Add(chartArea);
var seriesColumns = new System.Windows.Forms.DataVisualization.Charting.Series("Columns");
foreach (var val in new float[] { 6, 14, 3, 4, 2, 2, 1, 3 })  

    seriesColumns.Points.Add(Convert.ToDouble(val));
seriesColumns.ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Radar;
chart.Series.Add(seriesColumns);
