Hi R.B.,
You simply need to tell the line to use X values:

nl.UseXValues = true;

otherwise it will automatically assign x values that start from 0.

Hi,
I am trying to fill chart using a List<decimal> like this:
 for (int i =0; i<ListItems.Count; i++)
            {
nl.Values.Add(ListItems[i]);
            nl.XValues.Add(i+1);
}

but the first item always has xvalue = 0, how can I change it to start from 1 to 30?

Best regards,

R. B.
