[英]How to change/add chart data series in python-pptx?
I'm trying to set data in an existing chart using python-pptx. 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) (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
There's a method mentioned in the documentation which seems relevant, but I can't understand how to use it: http://python-pptx.readthedocs.org/en/latest/_modules/pptx/chart/data.html 文档中提到了一种看似相关的方法,但我不明白如何使用它: 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'
I'd appreciate any help you can provide. 谢谢您能提供的任何帮助。 Thanks!
谢谢!
To add a new series to an existing table behind a chart you need to do 3 things: 要将新系列添加到图表后面的现有表中,您需要做以下三件事:
add the new series to the ChartData() object, using the "add_series()" func. 使用“ add_series()”功能将新系列添加到ChartData()对象。
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)
