Generating Multiple Series For Chart From Same Data Source

I am importing data from an excel file, and it is stored in a dataset. The data is then filtered with a binding source, and that data is outputted into a datagridview. The filtered data in the datagridview contains data for 2 identification numbers. I want to graph each ID number in a chart on their own bar, in either a stacked bar graph, or a double bar graph.

I am having trouble assigning each series to an ID number: I have tried using multiple binding sources, but each seems to override the previous giving too much/too little data. I have tried using multiple datagridviews, however I cannot assign more than one datagridview as the datasource for the chart. The code I have pasted below outputs a double bar graph, however both bars graph the same ID number.

Private Sub dataButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dataButton.Click

Dim cnRange As String = "provider=Microsoft.Jet.OLEDB.4.0; " & _
"data source='" & strFileName & "';" & _
"Extended Properties=""Excel 8.0; IMEX=1; HDR=No;"""
