How can I create a chart like this??

This is my code. It is incomplete. Not sure on how to add the columns and the line to the Database.

Sub ColumnLineChart()

        Dim dt As New DataTable()

        dt.Columns.Contains("SiteCode")

        dt.Rows.Add(New [Object]() {"SiteCode"})

        Return

    End Sub

I want to know how do I manipulate the data in the Database to my ColumnLine Chart.

Really appreciate any help or hints I can get.
