Adding a Chart Title

 
Sub chartTitle()
    Dim myChartObject As ChartObject
    Set myChartObject = ActiveSheet.ChartObjects.Add(Left:=200, Top:=200, _
        Width:=400, Height:=300)
    
    myChartObject.Chart.SetSourceData Source:= _
        ActiveWorkbook.Sheets("Chart Data").Range("A1:E5")
    
    myChartObject.SeriesCollection.Add Source:=ActiveSheet.Range("C4:K4"), Rowcol:=xlRows
    myChartObject.SeriesCollection.NewSeries
    myChartObject.HasTitle = True
End Sub



Seaching for Charts Using the Chart Title

 
Function GetChartByCaption(ws As Worksheet, sCaption As String) As Chart
    Dim myChart As ChartObject
    Dim myChart As Chart
    Dim sTitle As String
    Set myChart = Nothing
    For Each myChart In ws.ChartObjects
        If myChart.Chart.HasTitle Then
            sTitle = myChart.Chart.ChartTitle.Caption
            If StrComp(sTitle, sCaption, vbTextCompare) = 0 Then
                Set myChart = myChart.Chart
                Exit For
            End If
        End If
    Next
    Set GetChartByCaption = myChart
    Set myChart = Nothing
    Set myChart = Nothing
End Function
Sub TestGetChartByCaption()
    Dim myChart As Chart
    Dim ws As Worksheet
    Set ws = ThisWorkbook.Worksheets("Sheet1")
    Set myChart = GetChartByCaption(ws, "I am the Chart Title")
    If Not myChart Is Nothing Then
        Debug.Print "Found chart"
    Else
        Debug.Print "Sorry - chart not found"
    End If
    Set ws = Nothing
    Set myChart = Nothing
End Sub



To change chart default title, set the Text property of the ChartTitle object, which represents the chart title

 
Sub charTitleText()
    ActiveChart.ChartTitle.Text = "Industrial Disease in North Dakota"
End Sub



To format the text of the title, work with its Font object

 
Sub format()
    Dim myChartObject As ChartObject
    Set myChartObject = ActiveSheet.ChartObjects.Add(Left:=200, Top:=200, _
        Width:=400, Height:=300)
    
    myChartObject.Chart.SetSourceData Source:= _
        ActiveWorkbook.Sheets("Chart Data").Range("A1:E5")
    
    myChartObject.SeriesCollection.Add Source:=ActiveSheet.Range("C4:K4"), Rowcol:=xlRows
    myChartObject.SeriesCollection.NewSeries
    myChartObject.HasTitle = True
    
    myChartObject.ChartTitle.Font.Name = "Times"
End Sub



To position the title, set its Top property (specifying the number of points from the top edge of the worksheet) and its Left property (specifying the number of points from the left edge of the worksheet)

 
Sub source()
    Dim myChartObject As ChartObject
    Set myChartObject = ActiveSheet.ChartObjects.Add(Left:=200, Top:=200, _
        Width:=400, Height:=300)
    
    myChartObject.Chart.SetSourceData Source:= _
        ActiveWorkbook.Sheets("Chart Data").Range("A1:E5")
    
    myChartObject.SeriesCollection.Add Source:=ActiveSheet.Range("C4:K4"), Rowcol:=xlRows
    myChartObject.SeriesCollection.NewSeries
    myChartObject.HasTitle = True
    With myChartObject.ChartTitle
        .Top = 100
        .Left = 150
    End With
End Sub
