Issue creating Stacked Column Chart

Question

I am trying to create a stacked column chart from the following data.
PrimaryAdvisorName AccountTypeName TotalCustodianValue Paul T1 100 John T2 200 John T3 300

but the issue I am facing is all the series gets stacked on the same x-axis label.I don't see other x-axis values

    foreach (ProfileLineItem x in data.LineItems)
            {

                Series s = new Series

                stackedColumnChart.Series.Add(s);

            }
