Hi,

I am atemping to add line label for each line in my scatter line chart. Since I don't use series, I use a datatable which has several columns, I swap the rows and columns to draw the line chart.. I wonder is there any way that I can set the line label? Thank you.

My code is as follows:

UltraChart1.ChartType = ChartType.ScatterLineChart;
GrowthChart growth = new GrowthChart();
DataTable dt1 = growth.SearchByGenderType("M", "Length");

UltraChart1.Axis.X.RangeMin = 0;
UltraChart1.Axis.X.RangeMax = 40;
UltraChart1.Axis.X.RangeType = AxisRangeType.Custom;

UltraChart1.Axis.Y.RangeMin = 0;
UltraChart1.Axis.Y.RangeMax = 120;
UltraChart1.Axis.Y.RangeType = AxisRangeType.Custom;

UltraChart1.Axis.X2.RangeMin = 0;
UltraChart1.Axis.X2.RangeMax = 40;
UltraChart1.Axis.X2.RangeType = AxisRangeType.Custom;

UltraChart1.Axis.Y2.RangeMin = 0;
UltraChart1.Axis.Y2.RangeMax = 120;
UltraChart1.Axis.Y2.RangeType = AxisRangeType.Custom;

UltraChart1.ScatterLineChart.LineData.DataSource = dt1;
UltraChart1.ScatterLineChart.LineData.SwapRowsAndColumns = true;
UltraChart1.ScatterLineChart.LineData.DataBind();

DataTable dt = new DataTable();
dt.Columns.Add("X-Axis", typeof(decimal));
dt.Columns.Add("Y-Axis", typeof(decimal));
dt.Rows.Add(new object[] { 6.5, 80 });
dt.Rows.Add(new object[] { 20, 90 });

UltraChart1.ScatterLineChart.ScatterData.DataSource = dt;
UltraChart1.ScatterLineChart.ScatterData.DataBind();
UltraChart1.ScatterLineChart.Scatter.ColumnX = 0;
UltraChart1.ScatterLineChart.Scatter.ColumnY = 1;

UltraChart1.ScatterLineChart.LineData.UseRowLabelsColumn = true;
UltraChart1.ScatterLineChart.LineData.RowLabelsColumn = 0;
