Python, Excel, and Charts using win32com

Python and MS Excel question - using win32com, I'm able to create a chart within Excel but i'm unable to move it within a worksheet. I've found code online to generate the chart:

import win32com.client
from win32com.client import constants as c

xl = win32com.client.gencache.EnsureDispatch('Excel.Application')
xl.Visible = True
wb = xl.Workbooks.Add()
ws = xl.ActiveSheet
ws.Range('A1').FormulaR1C1 = 'X'
ws.Range('B1').FormulaR1C1 = 'Y'
ws.Range('A2').FormulaR1C1 = 1
ws.Range('A3').FormulaR1C1 = 2
ws.Range('A4').FormulaR1C1 = 3
ws.Range('B2').FormulaR1C1 = 4
ws.Range('B3').FormulaR1C1 = 5
ws.Range('B4').FormulaR1C1 = 6
#ws.Range('A1:B4').Select()
ch = ws.Shapes.AddChart().Select()
xl.ActiveChart.ChartType = c.xlXYScatterLines
xl.ActiveChart.SetSourceData(Source=ws.Range("A1:B4"))
#ch.Location(10,10) # something like this?

How may I move the chart within the worksheet?

You can specify the location at the time of creation of the chart expression.AddChart(Type, Left, Top, Width, Height) see here.

If you don't want to embed the chart in a worksheet, you can create a chart sheet :

wb.Worksheets.Add(Type:=xlChart)

Caveat : Microsoft.interop.Excel not win32com, but should work.
