Programmatically generating charts in Excel 2010 VBA

Hi,

I'm struggling to come up with the code to programmatically add a series of charts to a test spreadsheet in Excel 2010 VBA.  Haven't used VBA a whole lot and less with charts.  

I've looked through a number of examples online and haven't found a combination that seems to work.  Can someone peek at this and suggest a good example to use or sample code?

The first tab is called Distributions.  A sample chart is to the right of the table, and the VBA code I've already created is in the workbook.

Much appreciated!

Do you want to create similar charts for each of the tables?

Yes; the only thing that would change is the height of the bars.  The code currently generates empty charts going down the right side.

This is what I came up with, it's a little rough but it seems to get the job done.
Option Explicit

Sub CreateCharts()
Dim ws As Worksheet
Dim cht As Chart
Dim chtObj As ChartObject
Dim ser As Series
Dim rng As Range
Dim rngData As Range
Dim I As Long

    Set ws = Sheets("Distributions")

    Set rng = ws.Range("B4:B8")
    
    Do
        Do
            If rngData Is Nothing Then
                Set rngData = rng
            Else
                Set rngData = Union(rngData, rng)

            End If
            Set rng = rng.Offset(, 2)
        Loop Until rng.Cells(1, 1).Value = ""

        Set chtObj = ws.ChartObjects.Add(ws.Cells(rng.Row, "I").Left, rng.Offset(-2).Top, rngData.Width * 2 * 3, rng.Resize(rng.Rows.Count + 2).Height)

        chtObj.Chart.SetSourceData Source:=rngData

        Set cht = chtObj.Chart

        cht.ChartType = XlChartType.xlColumnClustered
        I = 1
        For Each ser In cht.SeriesCollection
            ser.Name = "=" & rngData.Areas(I).Cells(1, 1).Offset(-2).Address(external:=True)
            I = I + 1
        Next ser
        
        Set rngData = Nothing
        
        Set rng = ws.Cells(rng.Row, 2).Resize(5)
        Set rng = rng.Offset(9)
        
    Loop Until rng.Cells(1, 1).Value = ""

End Sub

Good grief!  I've been messing with this for a day and a half. :)  Wow.  That's impressive.

Were I to want to add a title to each chart reflecting the table title (Wa Sales, etc.), how would that be added?

There's a LOT here for me to look up and see how you did that.  I can't thank you enough for the help!

This will add the chart title, put it after the code that sets the ChartType
        cht.SetElement msoElementChartTitleAboveChart
        cht.ChartTitle.Text = ws.Cells(rng.Cells(1, 1).Row - 2, "A").Value

Thanks much!

Where would one go to read up on the techniques you used in this?  I've read the Excel 2013 Power Programming with VBA by John Walkenbach but I don't recall seeing coding this sophisticated in it.
