This is just a part of the code.
For i = 1 To Total_Graphs
Sheet3.Select
Num_Variables = Sheet2.Range("Num_Variables").Offset(i - 1, 0).Value
ActiveSheet.Shapes.AddChart.Select
ActiveChart.ChartType = xlLine
ActiveChart.SetSourceData Source:=Sheet1.Range(Total_Variable_Range(i))
For j = 1 To Num_Variables
ActiveChart.SeriesCollection(j).Name = Sheet2.Range("List_format").Offset(i - 1, j - 1).Value
Next j
Next i
Now, i want to name the chart created myself, instead of excel giving the name automatically.
