    I'm creating a line chart with multiple series created dynamically.

    Here is the code.

    For Each mdItem As ModalityTrendWrapper In ModalityTrend
                Dim newSeries As New Telerik.Charting.ChartSeries()
                newSeries.Name = mdItem.Modality
                newSeries.Type = ChartSeriesType.Line
                 
                For Each dateCount As ModalityTrendItem In mdItem.DateCounts
                    Dim chrItem As New ChartSeriesItem()
                    chrItem.YValue = dateCount.Count
                    chrItem.Name = dateCount.Modality
                    chrItem.Label.TextBlock.Text = dateCount.Count
                    chrItem.ActiveRegion.Tooltip =dateCount.Modality
                    newSeries.Items.Add(chrItem)
                Next
     
     
                RadChart1.Series.Add(newSeries)
            Next
             
            Dim MaxValue As Integer = Enumerable.Range(0, CInt(ModalityTrend.Count)).Select(Function(ex) ModalityTrend(ex).DateCounts.Max(Function(dc) dc.Count)).Max()
            RadChart1.ClientSettings.XScale = DateList.Count / 7
            RadChart1.PlotArea.XAxis.AddRange(1, DateList.Count, 1)
            RadChart1.PlotArea.YAxis.MaxValue = MaxValue + 2
            For i As Integer = 0 To DateList.Count - 1
                RadChart1.PlotArea.XAxis(i).TextBlock.Text = DateList(i)
                RadChart1.PlotArea.XAxis(i).Appearance.Border.Visible = True
     
     
            Next


    For some reason the tooltips just aren't showing up.  Is there anything that I'm missing?

    Hello Javier,

    It is hard to say what is preventing the tooltips to appear in your scenario from the provided information. Could you please open a formal support ticket and send us your stripped down runnable project so that we can inspect it locally and support you better?

    will do.  It appears to break when I enable scrolling.

    I'm sorry that I omitted to see it from your code snippet. Unfortunately the tooltip functionality is not supported when zooming and scrolling is enabled for the chart control and it would not be possible to apply both of them simultaneously.

    Apologies for the inconvenience caused.

    Kind regards,

    You didn't miss it.  I forgot to mention it.
