How to give custom labels to x axis of chart contr

问题:

I am creating a windows project in which there is a requirement to plot a graph, for that i am using chart control.

The X-Axis of chart control has label from 0 to 100 with following code.

chart1.ChartAreas[0].AxisX.Minimum = 0;
chart1.ChartAreas[0].AxisX.Maximum = 100;

chart1.ChartAreas[0].AxisY.Minimum = 0;
chart1.ChartAreas[0].AxisY.Maximum = 200;

chart1.ChartAreas[0].AxisX.Interval = 25;
chart1.ChartAreas[0].AxisY.Interval = 25;

But i want to customize the label of X-Axis from 100 to 0.

I tried out following things.

chart1.ChartAreas[0].AxisX.Minimum = 0;
chart1.ChartAreas[0].AxisX.Maximum = 100;

chart1.ChartAreas[0].AxisY.Minimum = 0;
chart1.ChartAreas[0].AxisY.Maximum = 200;

chart1.ChartAreas[0].AxisX.Interval = 25;
chart1.ChartAreas[0].AxisY.Interval = 25;



string[] xval = { "100", "75", "50", "25", "0" };
for (int i = 0; i < xval.Length; i++)
{
  chart1.ChartAreas[0].AxisX.CustomLabels.Add(i + 0.5, i + 1.5, xval[i]);
  //chart1.ChartAreas[0].AxisX.CustomLabels.Add(xval[i]);
}

Series S1 = new Series();
S1.Points.AddXY(184,10);
S1.Points.AddXY(100,10);
S1.ChartType = SeriesChartType.Line;
S1.Color = Color.Red;
S1.Name = "Steam Inlet Saturation Temp";
chart1.Series.Add(S1);

Series S2 = new Series();
S2.Points.AddXY(100, 10);
S2.Points.AddXY(0, 10);
S2.ChartType = SeriesChartType.Line;
S2.Color = Color.Blue;
S2.Name = "Back Pressure Temp";
chart1.Series.Add(S2);

But this thing are not working for me.

Is there any one who did this before? Your prompt reply will be really appreciated thanks.

Following is the solution of my question.

string[] monthNames = { "100", "75" , "50" , "25" ,"0"};
int startOffset = -2;
int endOffset = 2;
foreach (string monthName in monthNames)
{
 CustomLabel monthLabel = new CustomLabel(startOffset, endOffset, monthName, 0, LabelMarkStyle.None);                        
 chart1.ChartAreas[0].AxisX.CustomLabels.Add(monthLabel);
 startOffset = startOffset + 25;
 endOffset = endOffset + 25;
}
