I tried this sample trying to solve a similar problem. I wanted to render a text label for every label that is an even number. Could not get it to work. Finally, I brute forced a list of labels and used the following code to solve it.
*****
int[] points = {1,5,2,3,6,9,4,16,3,17,8,2,25,22};
string[] labels = new string[points.Length];
for(int i = 0; i < points.Length; i++)
{
if(points[i] % 2 == 0)
labels[i] = points[i].ToString();
else
labels[i] = "";
}
for(int i = 0; i < labels.Length; i++)
{
chartControl1.PrimaryXAxis.Labels.Add (labels[i]);
}
chartControl1.PrimaryXAxis.ValueType = ChartValueType.Custom;
