    Set chartObj = ws.ChartObjects(1)
    
    ' Update chart data range
    chartObj.Chart.SetSourceData Source:=ws.Range("A1:C10")
End Sub

This snippet changes the chart’s data source to range A1, making it more dynamic.

4. Adding a Data Series

Adding additional data series to a chart can also be automated:

Sub AddDataSeries()
    Dim chartObj As ChartObject
    Set chartObj = ThisWorkbook.Sheets("Sheet1").ChartObjects(1)
    
    ' Add a new series
    With chartObj.Chart.SeriesCollection.NewSeries
        .Name = "Projected Sales"
        .Values = ThisWorkbook.Sheets("Sheet1").Range("C1:C10")
        .XValues = ThisWorkbook.Sheets("Sheet1").Range("A1:A10")
    End With
End Sub

This code adds a new data series named “Projected Sales” using the data in column C.
