Tool tip Issue with Microsoft charts RRS feed

  • Question

  • Hello,

    We are using the Microsoft charts controls (DataVisualization.Charting  having version  v3.5.0.0  ) for the windows application and are having trouble with displaying tool tip for the series when the data points  lie on  X and Y axis. We have set the Tool tip property to true for the series. The problem occurs only when the series and the axis coincides

    We have notice that this problem also occurs in the Sample examples downloaded from

    Below is the piece of code that we are using to draw the chart



            Chart1.Series("Series1").ToolTip = "  (#VALY{} , #VALX{})"

            Dim random As New Random()

            Dim pointIndex As Integer

            For pointIndex = 0 To 9

                If (pointIndex = 4 Or pointIndex = 5) Then

                    Chart1.Series("Series1").Points.AddXY(pointIndex, 0)


                    Chart1.Series("Series1").Points.AddXY(pointIndex, random.Next(45, 95))

                End If


            Next pointIndex


            Chart1.Series("Series1").ChartType = SeriesChartType.Line

            Chart1.ChartAreas("ChartArea1").AxisX.LabelStyle.IsEndLabelVisible = False

            Chart1.Series("Series1").IsValueShownAsLabel = False



    Thanks  in advance
