Activates the ChartObject named Chart 1

 
Sub activate()
    ActiveSheet.ChartObjects("Chart 1").Activate
End Sub



Add Chart

 
Sub AddChart()
  Dim aChart As Chart
  ActiveSheet.ChartObjects.Delete
  Set aChart = Charts.Add
  Set aChart = aChart.Location(Where:=xlLocationAsObject, Name:="Sheet1")
  With aChart
    .ChartType = xlColumnClustered
    .SetSourceData Source:=Sheets("Sheet1").Range("A3:D7"), _
      PlotBy:=xlRows
    .HasTitle = True
    .ChartTitle.Text = "=Sheet1!R3C1"
    With .Parent
      .Top = Range("F3").Top
      .Left = Range("F3").Left
      .Name = "MangoesChart"
    End With
  End With
End Sub



Adding a Chart Sheet Using VBA Code

    Charts.Add   "Create a chart sheet
    With ActiveChart    "Set chart properties
        .ChartType = xlColumnClustered
        .HasLegend = True
"        .Legend.Position = xlRight
        .Axes(xlCategory).MinorTickMark = xlOutside

In most cases you can avoid using the worksheet Index property

 
     Sub InsertChartsBeforeWorksheets2()
           Dim myWorksheet As Worksheet
           For Each myWorksheet In Worksheets
           Charts.add Before:=myWorksheet

           Next myWorksheet
     End Sub



Inserts a chart before each sheet

 
Sub InsertChartsBeforeWorksheets()
   Dim myWorksheet As Worksheet
 
   For Each myWorksheet In Worksheets

End Sub



Insert two chart sheets after the last worksheet in the active workbook. The chart sheets receive default names, such as Chart1 and Chart2:

 
Sub addAfter()
    ActiveWorkbook.Sheets.Add After:=Sheets(Sheets.Count), Count:=2, Type:=xlChart
End Sub



Modifying the chart type

 
Sub ModifyChart1()
    ActiveSheet.ChartObjects("Chart 1").activate
    ActiveChart.Type = xlArea
End Sub



Producing an Excel worksheet on a Word ocument

 
Sub MakeExcelChart()
    Dim XLSheet As Object
    
    Documents.Add
    Wbook = "\projections.xls"
    Set XLSheet = GetObject(Wbook, "Excel.Sheet").ActiveSheet
    
    XLSheet.range("Value") = 1
    XLSheet.range("Change") = 2
    XLSheet.Calculate
    Selection.Font.Size = 14
    Selection.Font.Bold = True
    Selection.TypeText "Monthly Increment: " & Format(2, "0.0%")
    Selection.TypeParagraph
    Selection.TypeParagraph
    XLSheet.range("data").Copy

    WS.Shapes.AddChart(xlColumnClustered, Left:=100, Top:=150, Width:=400, Height:=300).Select
    ActiveChart.SetSourceData Source:=WS.range("A1:E4")
End Sub



Retrieving data point labels from field names in the worksheet

 
Sub DataLabelsFromRange()
    Dim DLRange As range
    Dim myChart As Chart
    Dim i As Integer
    
    Set myChart = ActiveSheet.ChartObjects(1).Chart
    On Error Resume Next
    Set DLRange = Application.InputBox _
      (prompt:="Range for data labels?", Type:=8)
    If DLRange Is Nothing Then Exit Sub
    On Error GoTo 0
    myChart.SeriesCollection(1).ApplyDataLabels Type:=xlDataLabelsShowValue, AutoText:=True, LegendKey:=False
    Pts = myChart.SeriesCollection(1).Points.Count
    For i = 1 To Pts
        myChart.SeriesCollection(1). _
          Points(i).DataLabel.Characters.Text = DLRange(i)
    Next i
End Sub



Select a chart object

 
Sub m()
