The steps in VB.NET to populate a multiple series chart by manually adding xy points to the chart.

#vbdotnet

Dim months As New List(Of String)
Dim lowTemps As New List(Of Integer)
Dim highTemps As New List(Of Integer)

months.AddRange(New String() {"Jan", "Feb", "Mar", "Apr"})
lowTemps.AddRange(New Integer() {37, 41, 49, 56})
highTemps.AddRange(New Integer() {56, 61, 69, 77})

Chart1.Titles.Add("Monthly Average Temperature")
Chart1.Series.Clear()
Chart1.Series.Add("Low")

For i = 0 To months.Count - 1
Chart1.Series("Low").Points.AddXY(months(i), lowTemps(i))
Next

Chart1.Series.Add("High")

For i = 0 To months.Count - 1
Chart1.Series("High").Points.AddXY(months(i), highTemps(i))
