Python - Extra Excel Chart Series With Win32com

I'm writing some code for an assignment, and I need to create a simple column chart in Excel. This afternoon I found win32com (amazing tool by the way), but I've been suffering fro

Solution 1:

By observing the behavior of recording a macro in Excel which performs the same actions as we are replication in Python we can see that there does not appear to be a need to create a new series such as

series = chart.SeriesCollection().NewSeries()

I was able to simply reference an existing series

series = chart.SeriesCollection(1)

The following code seems to give me the desired behavior on my computer.

import win32com.client
xlApp = win32com.client.Dispatch('Excel.Application')

xlBook = xlApp.Workbooks.Add()

xlSheet = xlBook.Sheets(1)
xlSheet.Name = "Algoritmos de Busqueda"
xlSheet.Cells(1,1).Value="Secuencial"
xlSheet.Cells(2,1).Value="Binaria"
xlSheet.Cells(1,2).Value="32"
xlSheet.Cells(2,2).Value="32"

chart = xlApp.Charts.Add()
chart.Name= "Grafico "+xlSheet.Name
series = chart.SeriesCollection(1)
series.XValues= xlSheet.Range("A1:A2")
series.Values= xlSheet.Range("B1:B2")
series.Name= "Algoritmos"
chart.Axes()[0].HasMajorGridlines = True

This has been simplified to the bare minimum. I tested this in Python 2.7 with Excel 2003.
