  Hello, I am working with FlexChart (Win forms, VB.NET) and I am trying to create a chart which features:

  The X-Axis shows the months of the selected year.
  
  The Y-Axis shows the total amount of all quotes per user for each month.
  
  I need to be able to plot the Y-Axis values for multiple users, each with a line in a different colour.

  I can get it to display one user at a time but I am not sure how to display the data points for more than one user at the same time. Can you give me any hints in that regard?

  Thanks,

  Mike

  Hi Mike,

  FlexChart allows to provide individual data source for each Series. So, for your requirement you can structure your data source as a collection of monthly data(which is a collection again) for each user and create a Series for each user in the chart.

  For userId As Integer = 1 To 5
   If _data.Count < userId Then
    _data.Add(New ObservableCollection(Of DataItem)())
    Dim ser = New Series() With {
     .Name = "User " & userId,
     .DataSource = _data(userId - 1)
    }
    flexChart1.Series.Add(ser)
   End If
  Next
  
  Where _data is as follows:
  
  _data = New List(Of ObservableCollection(Of DataItem))()
  
  

  Please refer the attached sample(prj_MultiSourceVBFlexChart.zip) for complete implementation of the same.

  Thanks,

  You don’t have any VB samples do you? That is what I am working in.

  Hello,

  The sample shared by Basant was created in VB.Net language only. So, if you’re looking for any other sample in VB, please mention the specific name.

  Thanks,

  Thanks! Not sure how I missed that. That is exactly what I am looking for.
