VBでMSCHART　.NETの使い方を教えてください。以下のソースでArea3DStyle.Enable3D で実行時にエラーがでます。defaultがないとのことです。どのように直せばいいでしょうか？

Imports System.Windows.Forms.DataVisualization.Charting
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
DynamicChartCreation_Load(sender, e)
End Sub

Dim Chart1 As System.Windows.Forms.DataVisualization.Charting.Chart
Private Sub DynamicChartCreation_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Chart1 = New Chart()

Dim chartArea1 As New ChartArea()

Chart1.ChartAreas.Add(chartArea1)
Dim series1 As New Series()
Dim series2 As New Series()
　　　　　　データ代入は略
' Add series to the chart
Chart1.Series.Add(series1)
Chart1.Series.Add(series2)

Chart1.Location = New System.Drawing.Point(16, 48)

Chart1.Size = New System.Drawing.Size(360, 260)

Chart1.ChartAreas("Default").Area3DStyle.Enable3D = True　＜＝ここでDefaultがないとエラーが出る。

Me.Controls.AddRange(New System.Windows.Forms.Control() {Me.Chart1})
End Sub 'DynamicChartCreation_Load


End Class
