    wrong x'axis label.jpg

    I have a Chart with two series, the X axis use dateManual as annotation format. then I pass in six dates as X value.which date is the last day of each month. But the graph's X axis shows Jul Aug Oct Nov Dec. Sept is missing in between. how does that happen? how do I have "Sept" back on my graph?

    Code Sample:

    Dim dat() As Date = New Date() {New Date(2005, 7, 31), New Date(2005, 8, 31), New Date(2005, 9, 30), New Date(2005, 10, 31), New Date(2005, 11, 30), New Date(2005, 12, 31)}

    thisChart.ChartGroups(0).ChartData.SeriesList(0).PointData.Length = 6

    thisChart.ChartGroups(0).ChartData.SeriesList(1).PointData.Length = 6

    For i As Integer = 0 To 5

    thisChart.ChartGroups(0).ChartData.SeriesList(0).X(i) = dat(i)

    thisChart.ChartGroups(0).ChartData.SeriesList(0).Y(i) = i

    thisChart.ChartGroups(0).ChartData.SeriesList(1).X(i) = dat(i)

    thisChart.ChartGroups(0).ChartData.SeriesList(1).Y(i) = i

    Next

    Thanks!

    Hello,
     
    Try the given code snippet.
     
    BEGIN CODE

    Me.C1Chart1.ChartGroups(0).ChartData.SeriesList.Clear()

    Dim ds As C1.Win.C1Chart.ChartDataSeries = Me.C1Chart1.ChartGroups(0).ChartData.SeriesList.AddNewSeries

    Dim dat() As Date = New Date() {New Date(2005, 7, 31), New Date(2005, 8, 31), New Date(2005, 9, 30), _

                                    New Date(2005, 10, 31), New Date(2005, 11, 30), New Date(2005, 12, 31)}

    Me.C1Chart1.ChartGroups(0).ChartData.SeriesList(0).PointData.Length = 6

    ds.X.CopyDataIn(dat)

    For i As Integer = 0 To 5

    ds.Y(i) = i

    Next

    Me.C1Chart1.ChartArea.AxisX.AnnoFormat = C1.Win.C1Chart.FormatEnum.DateManual

    Me.C1Chart1.ChartArea.AxisX.AnnoFormatString = "MMMM"

    Me.C1Chart1.ChartArea.AxisX.SetMinMax(CDate("06/01/2005"), CDate("12/31/2005"))

    Me.C1Chart1.ChartArea.AxisX.UnitMajor = 30


    END CODE
     
    Hope this helps.

    I have tried your code snippet, the Date axis on the graph is now correct. but I am creting a column chart. the column is not drawn on the right date axis. the first column should be on august because i passed in "31th of july" for x1, not in between of august and september. any idea? Thanks!
