Forms Data Controls :: Chart Points Not Signed?

In the control Chart, I add few points, selected from the database:

var Diagram_1 = Razrez_D1.Series ["D1"];
sqlDA.SelectCommand.CommandType = CommandType.StoredProcedure;
sqlDA.SelectCommand.CommandText = "Razrez_D1";
sqlDA.SelectCommand.Parameters ["@ date1"]. Value = Session ["date1"]. ToString ();
sqlDA.SelectCommand.Parameters ["@ date2"]. Value = Session ["date2"]. ToString ();
sqlDA.Fill (dataSet1, "Razrez_D1");
sqlDA.SelectCommand.CommandType = CommandType.Text;
for (int i = 0; i <dataSet1.Razrez_D1.Rows.Count; i + +)
(
string name_s = dataSet1.Razrez_D1 [i]. Name.ToString ();
name_s = name_s.Substring (name_s.IndexOf ('№')). Trim ();
Diagram_1.Points.AddXY (name_s, dataSet1.Razrez_D1 [i]. Count);
Diagram_1.Points [i]. BorderColor = System.Drawing.Color.Black;;
Diagram_1.Points [i]. BorderWidth = 1;
if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> 5)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Red;
)
else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> = 4 & & Convert.ToInt32
(dataSet1.Razrez_D1 [i]. count) <= 5)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Yellow;
)
else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count) <4)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Green;
)
)

The problem is that the points on the X axis are signed that way: first is not signed, second is signed, third is not signed etc How can I sigh all points?
