使用Python win32com如何获取对图表数据表的引用?
我可以使用数据表创建图表(PowerPoint在单独的窗口中弹出) 像:
import win32com
from MSO import constants as msoconst
Application = win32com.client.Dispatch("PowerPoint.Application")
Application.Visible = True
Presentation = Application.Presentations.Add()
FirstSlide = Presentation.Slides.Add(1, 12)
... no problem adding slides, shapes and text and setting font size and color ....
InventoryChart = FirstSlide.Shapes.AddChart2(201,msoconst.xlColumnClustered ,10,80,470,220,False) # 0 = Clustered Column, 1 = Combo Area, 2 = Clustered Column
InventoryChartData = InventoryChart.ChartData
ChartData不起作用:AttributeError:''对象没有属性' ChartData'
那么,您如何获得PowerPoint创建的表的引用?或者如何定义用于我的数据的表?
答案 0 :(得分:1)
我有一段时间没有同样的问题,花了很多时间试图找到答案。
ChartData是Chart对象的属性。因此,要访问ChartData对象,您需要告诉PowerPoint您刚添加的形状是图表。
这有两种方法可以做到。
# Option 1 - Add .Chart to end of AddChart2 method
InventoryChart = FirstSlide.Shapes.AddChart2(201,msoconst.xlColumnClustered,10,80,470,220,False).Chart
# Option 2 - Define Chart object separate from AddChart2
InventoryChart = FirstSlide.Shapes(1).Chart
# You can now access the chart's data worksheet
InventoryChartData = InventoryChart.ChartData.Workbook.Worksheets(1)
# Write a value to worksheet
InventoryChartData.Range('F1').Value = 150
# Apply numeric formatting to Series 1 values
InventoryChartData.Range('B2:B5').NumberFormat = '0.00'
