ZedGraph labels

Question

In ZedGraph, how do I show text labels for each point and in the XAxis all together?

If I do

myPane.XAxis.Type = AxisType.Text;
myPane.

I've changed my answer after you clarified the question. You just have to remember to position the labels correctly:

<%
  System.Collections.Generic.List<ZedGraphWebPointPair> points = new System.Collections.Generic.List<ZedGraphWebPointPair>();
  for (int i = 0; i < 15; i++)
  {
    // Let's have some fun with maths
    points.Add(new ZedGraphWebPointPair
    {
      X = i,
      Y = Math.Pow(i - 10, 2) * -1 + 120
    });
  }

  System.Collections.Generic.List<string> XAxisLabels = new System.Collections.Generic.List<string>();

  TestGraph.CurveList.Add(new ZedGraphWebLineItem { Color = System.Drawing.Color.Red });
  TestGraph.XAxis.Scale.FontSpec.Size = 9;

  int j = 1;
  foreach (ZedGraphWebPointPair point in points)
  {
    // Add the points we calculated
    TestGraph.CurveList[0].Points.Add(point);

    // Add the labels for the points
    TestGraph.GraphObjList.Add(new ZedGraphWebTextObj
    {
      Location =
      {
        CoordinateFrame = ZedGraph.CoordType.XChartFractionYScale,
        // Make sure we position them according to the CoordinateFrame
        X = Convert.ToSingle(j) / points.Count - 0.05f,
        Y = Convert.ToSingle(point.Y) + 3f,
        AlignV = ZedGraph.AlignV.Top
      },
      Text = point.Y.ToString(),
      FontSpec = { Angle = 90, Size = 9, Border = { IsVisible = false } }
    });

    // Add the labels for the XAxis
    XAxisLabels.Add(String.Format("P{0}", j));

    j++;
  }

  TestGraph.RenderGraph += delegate(ZedGraphWeb zgw, System.Drawing.Graphics g, ZedGraph.MasterPane mp)
  {
    ZedGraph.GraphPane gp = mp[0];
    gp.XAxis.Type = ZedGraph.AxisType.Text;
    gp.XAxis.Scale.TextLabels = XAxisLabels.ToArray();
  };

%>

That code will produce this graph:

If the axis type is text, the code below is easier to get x-coordinates of the points ;)

for (int tPoint = 0; tPoint < curve.Points.Count; tPoint++)
{
    TextObj text = new TextObj(curve.Points[tPoint].Y.ToString(), curve.Points[tPoint].X, curve.Points[tPoint].Y + 10);
}
