I have a simple scatter chart to which I add a NumericTimeSeries.
I can switch on the data point labels and set the ItemFormatString = "<DATA_VALUE:##.##>".
But I cannot get it to display the Value from the NumericTimeSeries, I think it's trying to format the date using the format string!?
Is there a way of telling the chart to use the Value column from the NumericTimeSeries?
Many Thanks!
Try setting the axis Labels property ItemFormatString="<ITEM_LABEL>".
You can read more about it from the following link:

Let me know if you have further problems.
Many Thanks for the reply! Still not working though I'm afraid. Here is the code I'm using....

//Setup DataSource
DataTable table = new DataTable();table.Columns.Add("Date", typeof(DateTime));table.Columns.Add("Value", typeof(double));
double minValue=0;double maxValue=0;
foreach (MyData data in dataList){ table.Rows.Add(new object[] { data.Date, data.Value }); if (exceedenceHistory.Value > 0 && exceedenceHistory.Value > maxValue) { maxValue = exceedenceHistory.Value; } if (exceedenceHistory.Value < 0 && exceedenceHistory.Value < minValue) { minValue = exceedenceHistory.Value; }}
NumericTimeSeries series = new NumericTimeSeries();series.Data.TimeValueColumn = "Date";series.Data.ValueColumn = "Value";series.Data.DataSource = table;series.DataBind();this.UltraChart1.Series.Add(series);
//Setup Chartthis.UltraChart1.ChartType = ChartType.ScatterChart;this.UltraChart1.ScatterChart.ConnectWithLines = true;this.UltraChart1.ScatterChart.LineAppearance.SplineTension = 0;this.UltraChart1.Data.UseMinMax = true;this.UltraChart1.Data.ZeroAligned = true;this.UltraChart1.Tooltips.FormatString = "Run DateTime : <DATA_VALUE_X:dd-MM-yyyy HH:mm>\r\n" +"Value : <DATA_VALUE_Y:##.##>mm";this.UltraChart1.ScatterChart.Icon = SymbolIcon.Circle;this.UltraChart1.ScatterChart.IconSize = SymbolIconSize.Medium;

<<<<
I've tried using "<DATA_VALUE_Y:##.##>mm" as the format string as this works fine for the tooltip, but does not work for the item label, with the code above I get this as the output ...
Any help will be much appreciated!
