  I am downloading a datatable, then using the FlexChart.DataSource = mydatatable in vb.
  
  How do I update the flexchart?
  
  Sorry I’m learning C#.

  Hi,

  After setting FlexChart’s DataSource, you also need to add Series and set their Binding to the columns of the datatable as follows:

  
          Dim series1 As New C1.Win.Chart.Series()
          Dim series2 As New C1.Win.Chart.Series()
  
          ' name the series
          series1.Name = "Population (in million)"
          series2.Name = "GDP (in $Billion)"
  
          ' add the series to the series collection
          FlexChart1.Series.Add(series1)
          FlexChart1.Series.Add(series2)
  
          ' bind X-axis and Y-axis 
          FlexChart1.BindingX = "Country"
          series1.Binding = "Population"
          series2.Binding = "GDP"
  
  

  I have also uploaded a sample application binding C1FlexChart to a DataTable, you may download the same from: https://www.dropbox.com/s/k912xvng46anmoi/prj_C1FlexChart_VB.zip?dl=0
