使用 python win32com 创建数据透视图会导致 pywintypes.com_error [英] create a pivotchart with python win32com causes pywintypes.com_error

问题描述

有没有人可以给出在excel中创建数据透视图的示例代码?我有一个使用数据透视表创建数据透视表的示例，它可以工作，而当我尝试以相同的方式创建数据透视图时，它总是失败！

is there anyone can give a example code for creating a pivotchart in excel? I have got an example to create a pivottable with pivottable, it works , while when I try to create a pivotchart in the same ways, it will always failed!

import win32com.client
import os

Excel   = win32com.client.gencache.EnsureDispatch('Excel.Application') 
win32c  = win32com.client.constants
wb      = Excel.Workbooks.Add()
Sheet1  = wb.Worksheets.Add()
TestData = [['Country','Name','Gender','Sign','Amount'],
             ['CH','Max' ,'M','Plus',123.4567],
             ['CH','Max' ,'M','Minus',-23.4567],
             ['CH','Max' ,'M','Plus',12.2314],
             ['CH','Max' ,'M','Minus',-2.2314],
             ['CH','Sam' ,'M','Plus',453.7685],
             ['CH','Sam' ,'M','Minus',-53.7685],
             ['CH','Sara','F','Plus',777.666],
             ['CH','Sara','F','Minus',-77.666],
             ['DE','Hans','M','Plus',345.088],
             ['DE','Hans','M','Minus',-45.088],
             ['DE','Paul','M','Plus',222.455],
             ['DE','Paul','M','Minus',-22.455]]

for i, TestDataRow in enumerate(TestData):
    for j, TestDataItem in enumerate(TestDataRow):
        Sheet1.Cells(i+2,j+4).Value = TestDataItem

cl1 = Sheet1.Cells(2,4)
cl2 = Sheet1.Cells(2+len(TestData)-1,4+len(TestData[0])-1)
PivotSourceRange = Sheet1.Range(cl1,cl2)
PivotSourceRange.Select()

Sheet2 = wb.Worksheets("Sheet1")
cl3=Sheet2.Cells(4,1)
PivotTargetRange=  Sheet2.Range(cl3,cl3)
PivotTableName = 'ReportPivotTable'

PivotCache = wb.PivotCaches().Create(SourceType=win32c.xlDatabase, SourceData=PivotSourceRange, Version=win32c.xlPivotTableVersion14)
PivotTable = PivotCache.CreatePivotTable(TableDestination=PivotTargetRange, TableName=PivotTableName, DefaultVersion=win32c.xlPivotTableVersion14)
PivotChart = PivotCache.CreatePivotChart(ChartDestination="Sheet1")
Excel.Visible = 1
cwd = os.getcwd()
wb.SaveAs(os.path.join(cwd,'test.xlsx'))
Excel.Application.Quit()

它会一直报错:

Traceback (most recent call last):
  File "excelpivotchart.py", line 41, in <module>
    PivotChart = PivotCache.CreatePivotChart(ChartDestination="Sheet1")
  File "C:\Python27\lib\site-packages\win32com\gen_py\00020813-0000-0000-C000-000000000046x0x1x8\PivotCache.py", line 36, in CreatePivotChart
    , XlChartType, Left, Top, Width, Height
pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2146827284), None)

我设法让它发挥作用

import win32com.client
import os

Excel   = win32com.client.gencache.EnsureDispatch('Excel.Application') 
win32c  = win32com.client.constants
wb      = Excel.Workbooks.Add()
Sheet1  = wb.Worksheets.Add()
TestData = [['Country','Name','Gender','Sign','Amount'],
             ['CH','Max' ,'M','Plus',123.4567],

DataField = PivotTable.AddDataField(PivotTable.PivotFields('Amount'))

#Creating the PivotChart

chart=Sheet2.Shapes.AddChart2(201)
#to change XlChartType,cf.https://msdn.microsoft.com/fr-fr/vba/excelvba/articles/shapes-addchart2-method-excel
#For example, you can do chart=Sheet2.Shapes.AddChart2(201,4) for xlLine chart


Excel.Visible = 1
