如何使用Python和win32com.client将数据添加到Excel图表中

Question

I have been looking at here: https://msdn.microsoft.com/en-us/vba/excel-vba/articles/object-model-excel-vba-reference

I created a chart in Excel manually and recorded the macro. Using that I am trying to navigate which methods to use. In my code below, ch is an embedded chart object in the worksheet. According to the above link, it should have a method called SetSourceData which takes Range as a required parameter.

import win32com.client as wc

xl = wc.Dispatch("Excel.Application")
xl.Visible = True
wb = xl.Workbooks.Add() 
ws = wb.Worksheets.Add()
ws.Name = 'New Sheet'

ws.Cells(5,5).Value = 1
ws.Cells(6,5).Value = 1
ws.Cells(5,6).Value = 1
ws.Cells(6,6).Value = 1

ch = ws.ChartObjects().Add(100, 100, 100, 100)

#everything above works fine. problem is I can't add data to my chart.

ch.SetDataSource("E5:F5")

When I run the above, I get the following error:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-47-5b5d1a6d3109> in <module>()
     30 ws.Cells(6,6).Value = 1
     31 
---> 32 ch.SetDataSource("E5:F5")

    528 
    529         def __setattr__(self, attr, value):

AttributeError: Add.SetDataSource

Is there a way to show which methods are available when I import win32com.client? Right now, I have to keep going to the MS website and dig through each method for chart creating/formatting, which is not efficient, but instructive I must admit.

Answer 1

ch.SetDataSource(Source=ws.Range('E5:F5'))
