Dynamic Chart Generation
 

I am trying to use VBA to dynamically produce a number of charts. The
number of charts produced depends on the amount of data that appears in
a seperate spreadsheet...

I have taken the code produced when I recorded a macro to produce one
such chart and adapted it to meet my needs, however I am getting error
1004, "Unable to set the XValues property of the Series class" when I
try to assign the x-axis values using a range I have dynamically
created.

I'm sure the problem is somewhere with my syntax, but however I try to
phrase it I cannot seem to get it to work.

Please find a copy of my code below - any help would be much
appreciated!

In the following code the variable Count determines how many charts
will need to be produced:

<code
Dim i As Integer
Dim Count As Integer
Dim intGraphDisplayStartRow As Integer
Dim rngTempRange1 As Range
Dim rngTempRange2 As Range
Dim rngTempRange3 As Range


If Count 0 Then
For i = 1 To Count
intGraphDisplayStartRow = (i * 13) + 2
ThisWorkbook.Worksheets("Page 2").Select

Charts.Add
Set rngTempRange1 =
ThisWorkbook.Worksheets("WorkspaceTemp") _
.Range("A" & Trim(CStr(intGraphDisplayStartRow _
& ":A" & intGraphDisplayStartRow + 11)))
Set rngTempRange2 =
ThisWorkbook.Worksheets("WorkspaceTemp") _
.Range("C" & Trim(CStr(intGraphDisplayStartRow)) & ":C"
_
& Trim(CStr(intGraphDisplayStartRow + 11)))
Set rngTempRange3 =
ThisWorkbook.Worksheets("WorkspaceTemp") _
.Range("C" & Trim(CStr(intGraphDisplayStartRow - 1)))

ActiveChart.ChartType = xlLine
ActiveChart.SeriesCollection(1).XValues = rngTempRange1
ActiveChart.SeriesCollection(1).Values = rngTempRange2
ActiveChart.SeriesCollection(1).Name = rngTempRange3
ActiveChart.Location Whe=xlLocationAsObject, Name:="Page
2"

Next
End If
</code

Hi jonwatts,

The only thing wrong with your code is that when you create a new chart
Series(1) does not exist, so you need to add a new series. Try this
slightly modified version.

Dim i As Integer
Dim Count As Integer
Dim iStartRow As Integer
Dim iEndRow As Integer
Dim rngTempRange1 As Range
Dim rngTempRange2 As Range
Dim rngTempRange3 As Range
Dim wks As Worksheet

' Just for neatness, and so I could test on my own
' worksheet, we set a variable for the worksheet
Count = 2
Set wks = ThisWorkbook.Worksheets("WorkspaceTemp")

If Count 0 Then
For i = 1 To Count
iStartRow = (i * 13) + 2
iEndRow = iStartRow + 11 ' iEndRow calculated here, makes the range
calcs shorter
ThisWorkbook.Worksheets("Page 2").Select

Set rngTempRange1 = wks.Range("A" & Trim(CStr(iStartRow & ":A" &
iEndRow)))
Set rngTempRange2 = wks.Range("C" & Trim(CStr(iStartRow)) & ":C" &
Trim(CStr(iEndRow)))
Set rngTempRange3 = wks.Range("C" & Trim(CStr(iStartRow - 1)))

Charts.Add
With ActiveChart
.ChartType = xlLine
.SeriesCollection.Add rngTempRange2 ' the only change you really
need
.SeriesCollection(1).XValues = rngTempRange1
.SeriesCollection(1).Name = rngTempRange3
.Location Whe=xlLocationAsObject, Name:="Page 2"
End With
ActiveChart.Parent.Top = iStartRow * 5
ActiveChart.Parent.Left = iStartRow * 5
Next
End If

A further refinement is to use

Worksheets("Page 2").ChartObjects.Add(<dimensions)

rather than

Charts.Add
...
ActiveChart.Location Whe=xlLocationAsObject, Name:="Page 2"

Work your position parameters

ActiveChart.Parent.Top = iStartRow * 5
ActiveChart.Parent.Left = iStartRow * 5

into the left, top, width, and height dimensions in the ChartObjects.Add
statement.
