I have an X-Y scatter plot as an embedded chart. I have a list of X & Y
values that I would like to use to draw vertical lines on the chart. The
range for x-series is AB10:AC33, and I would like to use the same values to
define the y-values (AD10:AE10). I started by recording a macro for adding
one series to the chart, then tried to generalize using a for...next loop for
adding all 24. This of course did not work. Here is my code:
Private Sub combobox_2_click()

Dim i As Integer
Dim num As Integer
Dim myRange As Range

If Range("focus_choice") = "All" Then

Application.ScreenUpdating = False
Worksheets(2).Activate
Set myRange = Range("chr_start")
num = ActiveSheet.ChartObjects(1).Chart.SeriesCollection .count


For i = 1 To 24
With ActiveSheet
.ChartObjects(1).Chart.SeriesCollection.NewSeries
.ChartObjects(1).Chart.SeriesCollection(1).Series( num +
1).XValues = myRange.Offset(i, 0)
.ChartObjects(1).Chart.SeriesCollection(1).Series( num +
1).Values = Worksheets(2).Range(Cells(30, 10), Cells(31, 10))
End With

With
ActiveSheet.ChartObjects(1).Chart.SeriesCollection (1).Series(num + 1).Border
.ColorIndex = vbWhite
.LineStyle = xlContinuous
End With

With
ActiveSheet.ChartObjects(1).Chart.SeriesCollection (1).Series(num + 1)
.MarkerStyle = xlNone
End With

Next i

End If

Application.ScreenUpdating = True

End Sub


This does not work because I get an error message that says the "object
doesn't support this method or property" for the second assignment after the
for i = 1 to 24 (.ChartObjects(1).Chart.SeriesCollection(1).Series (num +
1).XValues = myRange.Offset(i, 0)). I know this can be done, but I need
help, so ... please help.

Thanks in advance,

Warren
