I have an UltraDataChart with a CategoryXAxis and NumericYAxis and am adding 2 ColumnSeries with the same datasource but different ValueMemberPath to it.  I want the corners to be rounded like shown in examples but no matter what I set RadiusX and RadiusY to it has NO effect on the columns at all they are still very rectangular.  Ive tried values from -1000 to 1000 and it never changes anything.

Heres a snippet of the code:

var xAxis = ultraDataChart1.Axes.OfType<CategoryXAxis>().First();
xAxis.DataSource = data;
xAxis.Label = "Date";

NumericYAxis yAxis = ultraDataChart1.Axes.OfType<NumericYAxis>().First();
yAxis.Label = "Usage";

for (var i = 0; i < servicesActive.Count; i++)
{
    var series = new ColumnSeries();
    series.XAxis = xAxis;
    series.YAxis = yAxis;
    series.DataSource = data;
    series.ValueMemberPath = "Service" + (i + 1);

    series.RadiusX = 10;
    series.RadiusY = 10;

    ultraDataChart1.Series.Add(series);
}
