VB

hello !

I am currently on a project in VB.NET and I would like to know how to make a graph passing through a combo box that takes data from a datagridview.

Me.FlowByBankTableAdapter.Fill(Me.Données_ProjetDataSet.FlowByBank)
       Chart3.Series(0).ChartType = DataVisualization.Charting.SeriesChartType.StackedColumn
       Chart3.Series(0).Points.Clear()

      If ComboBox1.SelectedText Then
           For Count As Integer = 0 To DataGridView1.Rows.Count - 1
            Chart3.Series(0).ChartType = System.Enum.Parse(GetType(System.Windows.Forms.DataVisualization.Charting.SeriesChartType), ComboBox1.SelectedValue.ToString)

           Next
       End If
