How to set the top argument of the ChartObjects.Add method dynamically

Hello,

I have a worksheet that consists of a datatable and five charts.  The table is dynamic in size.  I'lm trying to modify my code so that the charts will move up or down so that the distance between the charts and the datatable remains constant.  I am creating the charts and in fact via automation from Access.  Everything populates fine.  I think I may have to use the current.region property in the top argument but am not sure how.  In addition, I'm not sure how to convert the currentregion to points.

Set objXlChart = objXLSheet.ChartObjects.Add(Left:=75, Width:=750, Top:=150, Height:=300).Chart


Private Sub CreateNE_TotalPercentItemsAvailableChart(objWS As Object)
Dim objXLSheet As Object
Dim objXlChart As Object
Dim objXlDataSheet As Object
Dim rng As Object
Dim rngChart As Object

Set objXLSheet = objWS
Set objXlDataSheet = objXlBook.Worksheets("Summary")
Set rng = objXlDataSheet.Range("A:A,D:D")

Set objXlChart = objXLSheet.ChartObjects.Add(Left:=75, Width:=750, Top:=150, Height:=300).Chart



    With objXlChart
        .ChartType = 4  'xlLine
        .SetSourceData Source:=rng
        .PlotBy = 2
        .HasTitle = True
        .ChartTitle.Text = "Norgren Express" & vbCrLf & "Total Items % Available"
        .HasLegend = False
        .Axes(2).TickLabels.NumberFormat = "0%"
        .Axes(2).TickLabels.Orientation = 0
        .Axes(1).TickLabels.Orientation = 60
        .ChartStyle = 31
    End With

End Sub

Is this in a Report r a form?
What about page breaks?
Move the chart?, ...or do you mean shrink/grow?

This is all difficult to visualize...
Can you post a screenshot of what you have now, ...then post a clear graphical example of what you want it to be...?

I have done something like this for Images,...so the same  technique might be useful here.

convert the value of the Top parameter to a variable.

dim xTop as long
xTop=150 ' start of the chart vertical location

then just add the height of the chart + space to xTop variable as you are plotting the succeeding charts

I want to be able to set the value of xtop for the first chart equal to the height of the currentregion of the datatable   (which is the datasource for the graphs and which may expand according to the underlying recordset" plus a space of 50 points

I populate the datatable from a query.  It's jus a dataset that is used to populate a chart.  Depending on the data, it can be more or less rows.

<I populate the datatable from a query>

are you using vba to do this or copy and paste

I am using vba. I have a query and I am using the copy recordset method to put the results of the query on the worksheet.  I am then generating several charts from that data.  I want to ensure that no matter how many rows of data are returned that the charts do not end up overlapping one another or the dataset at the top of the worksheet.

after the copyfromrecordset line,

you can get the number of rows that was used with

objXlDataSheet.UsedRange.rows.count

from here you can based your starting xTop variable

I've attached a screenshot of the worksheet.  I want to dynamically position the top position of each chart so that they will never overlap

objXlDataSheet.UsedRange.rows.count
From reading about the top argument, it uses points.  Is there a way to convert the rows count to point?  It seems like they are apples and oranges
