  Hi,

  I am sorry but I could not observe any issue in displaying series while using DataTable as DataSource for the chart/series. Please refer to the attached modified sample for the same and let me know if something else is to be done?

  Also, the sample you provided was WinForms sample(whereas query is created in WPF Edition forum) so, I am assuming that you need help for WinForms FlexChart only.

  Hi Basant，

  Sorry I provided the wrong code, I cannot bind datatable on WPF,

  In fact, I have another question about the provided Winforms demo.

  How do I change the order of the Y axis or the legend of the two series ? My purpose is to make the order of the Y axis is same as the legend order.
  
  Keep the blue legend to the left of the red

  Hi,

  In the case of WPF FlexChart, you need to provide DataView of the required DataTable to the ItemsSource of the chart/series.

  ser1.ItemsSource = dataAAA.AsDataView();
  ser2.ItemsSource = dataBBB.AsDataView();

  In order to change(reverse in your case) the order of legends, you can simply set Legend.Reversed property to true.

  flexChart1.Legend.Reversed = true;
