python-pptx 實踐 6：添加圖表、設置圖例

1、顯示圖例的簇狀柱形圖

# import
import os
from pptx import Presentation
from pptx.util import Cm
from pptx.chart.data import ChartData
from pptx.enum.chart import XL_CHART_TYPE, XL_LEGEND_POSITION

# 設置路徑
work_path = r'E:\pyspace\tmp\pptx'
os.chdir(work_path) 

# 創建幻燈片  -------------------------------------------------
prs = Presentation()    # 初始化 ppt 文檔
title_only_slide = prs.slide_layouts[5]
slide = prs.slides.add_slide(title_only_slide)    # 添加幻燈片
shapes = slide.shapes
shapes.title.text = '各區銷量和收入數據'

# 定義圖表數據 -------------------------------------------------
chart_data = ChartData()    # 初始化
chart_data.categories = ['東區', '西區', '南區', '北區']
chart_data.add_series('銷量', (199, 214, 167, 221))
chart_data.add_series('收入', (211, 235, 188, 258))
 
# 將圖表添加到幻燈片 -------------------------------------------------
left, top, width, height = Cm(1), Cm(4), Cm(23), Cm(15)
graphic_frame = shapes.add_chart(chart_type=XL_CHART_TYPE.COLUMN_CLUSTERED,    # 圖表類型為簇狀柱形圖
                                 x=left, y=top,    # 圖表區左上角在幻燈片中的坐標位置
                                 cx=width,  cy=height,     # 圖表區的長和寬
                                 chart_data=chart_data    # 圖表數據
                                )

# 添加圖例 -------------------------------------------------
chart= graphic_frame.chart
chart.has_legend = True    # 顯示圖例
chart.legend.position = XL_LEGEND_POSITION.RIGHT    # 圖例顯示位置
chart.legend.include_in_layout = False    # 圖例在繪圖區之外顯示

# 保存 ppt 文檔
prs.save('test.pptx')

效果：
