我正在尝试使用python-pptx在现有图表中设置数据。
from pptx import Presentation
pres_path = "C:\\pres.pptx"
pres = Presentation(pres_path)
pres.slides[3].shapes[4].chart.series[0].values
(92.0,330.0,309.0,313.0,356.0,421.0,457.0)
pres.slides[3].shapes[4].chart.series[0].values = (1,2,3)
Traceback (most recent call last):
File "<input>", line 1, in <module>
AttributeError: can't set attribute
文档中提到的方法似乎相关,但我无法理解如何使用它: http://python-pptx.readthedocs.org/en/latest/_modules/pptx/chart/data.html
pres.slides[3].shapes[4].chart.replace_data((1,2,3))
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "C:\Python27\lib\site-packages\pptx\chart\chart.py", line 119, in replace_data
_SeriesRewriter.replace_series_data(self._chartSpace, chart_data)
File "C:\Python27\lib\site-packages\pptx\chart\chart.py", line 197, in replace_series_data
sers = cls._adjust_ser_count(chartSpace, len(chart_data.series))
AttributeError: 'tuple' object has no attribute 'series'
我很感激您提供的任何帮助。 谢谢!

要将新系列添加到图表后面的现有表格,您需要做三件事:
使用&#34; add_series()&#34;将新系列添加到ChartData()对象中。闪光功能
chart_data = ChartData()
chart_data.categories = 'category_name'
for col_idx, col in enumerate(single_df.columns):
chart_data.add_series(col, (single_df.ix[:, col_idx].values))
shp.chart.replace_data(chart_data)
