    chart1.Series[0].Points.AddXY(0, 1);
    chart1.Series[0].Points.AddXY(7, 1;
    chart1.Series[0].Points.AddXY(8,1);

3点がこんな感じになるといいなと思っていました

 .      . .

でもこんな感じでした

なんで？ありがとうございました

問題が見つかりました。

 series1.IsXValueIndexed = true;

これが起こった理由です。それは誤りであるはずです。皆様のご注目に感謝いたします。

空のDataPointを使用する必要があると思います（http://msdn.microsoft.com/en-us/library/dd456677.aspxを参照）

IsEmptyプロパティを使用すると、次のコードになります。（DataManipulator.InsertEmptyPoints必要なコードは少ないはずですが、まだテストしていません）

chart1.Series[0].Points.Add(new DataPoint(0,1));
chart1.Series[0].Points.Add(new DataPoint(1,0){IsEmpty=true});
chart1.Series[0].Points.Add(new DataPoint(2,0){IsEmpty=true});
chart1.Series[0].Points.Add(new DataPoint(3,0){IsEmpty=true});
chart1.Series[0].Points.Add(new DataPoint(4,0){IsEmpty=true});
chart1.Series[0].Points.Add(new DataPoint(5,0){IsEmpty=true});
chart1.Series[0].Points.Add(new DataPoint(6,0){IsEmpty=true});
chart1.Series[0].Points.Add(new DataPoint(7,1));
chart1.Series[0].Points.Add(new DataPoint(8,1));
