Is there any idea what he is doing in the below code at line
"chartSeries.AddItem(new ChartSeriesItem(listData[i].x, listData[i].y));"
I took this code from one forum.

I was not able to understand what kind of data holder it is?
如果我能够把数据集与清单数据联系起来,那么用数据形式将数据从数据集中抽取,我会促成这一发展。 但是,我不需要如何使这一约束力。
我曾尝试过如下,但 did不奏效, error一差错。
Dim listdata As new DataList
listdata.DataSource = ds.Tables.Item(0)
listdata.DataBind()

ChartSeries chartSeries = new ChartSeries("Altitude", ChartSeriesType.Line);
chartSeries.Appearance.ShowLabels = false;
incrementCount = 1;
for (int i = 0; i < listData.Count; i = i + incrementCount)
{
chartSeries.AddItem(new ChartSeriesItem(listData[i].x, listData[i].y));
}
RadChart2.AddChartSeries(chartSeries);
RadChart2.PlotArea.XAxis.AxisLabel.TextBlock.Text = "Distance (Miles)";
RadChart2.PlotArea.YAxis.AxisLabel.TextBlock.Text = "Yaxislabel";
