[feature]add add_chart for docx using chart from python-pptx.

[KehaoWu]

Hi, I create a new feature branch to add new feature: add_chart for docx.

The add_chart method allow us to add chart from python-pptx to docx. I request to merge to master branch and release as v0.8.7 or something.

Best wishes.

[mrxliu]

[sdnu]

Can you put an example for use

[vba34520]

It does work, Thanks!

My version

python-docx 0.8.10
python-pptx 0.6.18

Attention, in my version, docx/parts/document.py should import another class.

from pptx.parts.chart import ChartPart
from docx.oxml.shape import CT_Inline

chart can be editted.

Example code

from docx import Document
from pptx.util import Pt, Inches
from pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE, XL_LEGEND_POSITION, XL_DATA_LABEL_POSITION

document = Document()
chart_data = CategoryChartData()
chart_data.categories = ['East', 'West', 'Midwest']
chart_data.add_series('Series 1', (19.2, 21.4, 16.7))
x, y, cx, cy = Inches(2), Inches(2), Inches(6), Inches(4.5)
chart = document.add_chart(XL_CHART_TYPE.COLUMN_CLUSTERED, x, y, cx, cy, chart_data)

chart.has_legend = True
chart.legend.position = XL_LEGEND_POSITION.BOTTOM
chart.legend.include_in_layout = False

plot = chart.plots[0]
plot.has_data_labels = True
data_labels = plot.data_labels
data_labels.font.size = Pt(13)
data_labels.position = XL_DATA_LABEL_POSITION.OUTSIDE_END

chart.has_title = True
chart_title = chart.chart_title
text_frame = chart_title.text_frame
text_frame.text = 'Title'
paragraphs = text_frame.paragraphs
paragraph = paragraphs[0]
paragraph.font.size = Pt(18)

category_axis = chart.category_axis
category_axis.tick_labels.font.size = Pt(14)

document.save('test.docx')

Result

You can directly download the editted files. Use the folder of 替换 to cover the files on folder of docx. Like C:\Users\Administrator\AppData\Local\Programs\Python\Python36\Lib\site-packages\docx

why chart add in run，in my opinion chart is a part. actually, what I need is replace the data in chart. I can create template myself, but I need to render the xml, and replace the chart data, autofit the axis. I think this is what most people need.

[ym500]

can this method be used with python docx template?

Is there any update on this issue?

But how can i remove the border around the chart.

While implementing @vba34520 's code snippet, I got this error: AttributeError: 'Document' object has no attribute 'add_chart'.
How can I solve it?

@workamiracle You need to be using their version of python-docx because add_chart is not part of the main repo. I also suggest using an older version of python because some of the modules used have been moved in 3.10. (Working on python 3.6)

请在此处获取monkey.py文件monkey.txt
我通过整合KehaoWu的代码，创建了monkey.py这个文件，使用monkey patching的办法为docx增加了添加可编辑图表的功能。 使用示例参考
1，需要在代码中引入该文件import monkey,，
2，需修改docx/oxml/shape.py，65行，增加cChart = ZeroOrOne('c:chart')，即可成功使用。
测试版本：
python 3.11
python-docx 1.1.2
python-pptx 0.6.23

示例代码：
`from docx import Document
from pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE
from pptx.util import Cm

import monkey

document = Document()
chart_data = CategoryChartData()
chart_data.categories = ["apple", "banana", "grape"]
chart_data.add_series("Series 1", (19, 30, 7))
chart = document.add_chart(
XL_CHART_TYPE.COLUMN_CLUSTERED, 0, 0, Cm(15.2), Cm(11.4), chart_data
)

document.save("test.docx")
`
不过未经严格测试，请谨慎使用

Did you find any way to remove the borders or "outlines" around the chart?
