python-pptx 實踐 6.1：添加五種基本圖形（柱形圖、折線圖、餅圖、條形圖、散點圖）

柱形圖、折線圖、餅圖、條形圖、散點圖

0、import

 

import numpy as np from pptx import Presentation from pptx.util import Inches, Pt from pptx.chart.data import ChartData, XyChartData from pptx.dml.color import RGBColor from pptx.enum.chart import XL_CHART_TYPE, XL_LEGEND_POSITION, XL_TICK_MARK, XL_LABEL_POSITION

 

1、柱形圖

# 創建幻燈片-------------------------------------------------
prs = Presentation()    # 初始化 ppt 文檔
title_only_slide_layout = prs.slide_layouts[5]    # 選擇空白幻燈片版式
slide = prs.slides.add_slide(title_only_slide_layout)    # 添加一頁空白幻燈片
shapes = slide.shapes shapes.title.text = '簡單柱形圖'

# 定義圖表數據-------------------------------------------------
x = ['Q1', 'Q2', 'Q3', 'Q4'] y = [8888, 8899, 7788, 9988] chart_data = ChartData() chart_data.categories = x chart_data.add_series(name='銷量', values=y) # 添加圖表-------------------------------------------------
left, top, width, height = Inches(0.5), Inches(1.5), Inches(9), Inches(6) graphic_frame = shapes.add_chart(chart_type=XL_CHART_TYPE.COLUMN_CLUSTERED,  # 簇狀柱形圖
                                 x=left, y=top,    # 圖表區的位置
                                 cx=width, cy=height,    # 圖表的寬和高
                                 chart_data=chart_data) # 保存 ppt 文檔
prs.save('test.pptx')

 2、折線圖

# 創建幻燈片-------------------------------------------------
prs = Presentation()    # 初始化 ppt 文檔
title_only_slide_layout = prs.slide_layouts[5]    # 選擇空白幻燈片版式
slide = prs.slides.add_slide(title_only_slide_layout)    # 添加一頁空白幻燈片
shapes = slide.shapes shapes.title.text = '折線圖'

# 定義圖表數據-------------------------------------------------
x = ['Q1', 'Q2', 'Q3', 'Q4'] y = [8888, 8899, 7788, 9988] chart_data = ChartData() chart_data.categories = x chart_data.add_series(name='銷量', values=y) # 添加圖表-------------------------------------------------
left, top, width, height = Inches(0.5), Inches(1.5), Inches(9), Inches(6) graphic_frame = shapes.add_chart(chart_type=XL_CHART_TYPE.LINE,  # 圖表類型
                                 x=left, y=top,    # 圖表區的位置
                                 cx=width, cy=height,    # 圖表的寬和高

prs.save('test.pptx')

ppt 效果：

3、餅圖

# 創建幻燈片-------------------------------------------------

title_only_slide_layout = prs.slide_layouts[5]    # 選擇空白幻燈片版式
slide = prs.slides.add_slide(title_only_slide_layout)    # 添加一頁空白幻燈片
shapes = slide.shapes shapes.title.text = '餅圖'

# 定義圖表數據-------------------------------------------------
x = ['Q1', 'Q2', 'Q3', 'Q4'] y = [8888, 8899, 7788, 9988] chart_data = ChartData() chart_data.categories = x chart_data.add_series(name='銷量', values=y) # 添加圖表-------------------------------------------------
left, top, width, height = Inches(0.5), Inches(1.5), Inches(9), Inches(6) graphic_frame = shapes.add_chart(chart_type=XL_CHART_TYPE.PIE,  # 圖表類型
                                 x=left, y=top,    # 圖表區的位置
                                 cx=width, cy=height,    # 圖表的寬和高
                                 chart_data=chart_data) chart = graphic_frame.chart plot = chart.plots[0] # 設置數據標簽
plot.has_data_labels = True    # 顯示數據標簽
data_labels = plot.data_labels    # 獲取數據標簽控制類
data_labels.show_category_name = True    # 是否顯示類別名稱
data_labels.show_value = False    # 是否顯示值
data_labels.show_percentage = True    # 是否顯示百分比
data_labels.number_format = '0.0%'    # 標簽的數字格式
data_labels.position = XL_LABEL_POSITION.INSIDE_END    # 標簽位置
data_labels.font.name = 'Arial' data_labels.font.size = Pt(14) # 設置圖表標題
chart.has_title = True    # 顯示標題
para = chart.chart_title.text_frame.add_paragraph() para.text = '銷量占比'    # 標題內容
para.font.size = Pt(16)    # 字體大小

# 保存 ppt 文檔
prs.save('test.pptx')

 4、條形圖

# 創建幻燈片-------------------------------------------------
prs = Presentation()    # 初始化 ppt 文檔
title_only_slide_layout = prs.slide_layouts[5]    # 選擇空白幻燈片版式
slide = prs.slides.add_slide(title_only_slide_layout)    # 添加一頁空白幻燈片
shapes = slide.shapes shapes.title.text = '條形圖'

# 定義圖表數據-------------------------------------------------
x = ['Q1', 'Q2', 'Q3', 'Q4'] y = [8888, 8899, 7788, 9988] chart_data = ChartData() chart_data.categories = x chart_data.add_series(name='銷量', values=y) # 添加圖表-------------------------------------------------
left, top, width, height = Inches(0.5), Inches(1.5), Inches(9), Inches(6) graphic_frame = shapes.add_chart(chart_type=XL_CHART_TYPE.BAR_CLUSTERED,  # 圖表類型
                                 x=left, y=top,    # 圖表區的位置
                                 cx=width, cy=height,    # 圖表的寬和高
                                 chart_data=chart_data) chart = graphic_frame.chart plot = chart.plots[0] # 設置數據標簽
plot.has_data_labels = True    # 顯示數據標簽
data_labels = plot.data_labels    # 獲取數據標簽控制類
data_labels.number_format = '#,#'    # 標簽的數字格式
data_labels.position = XL_LABEL_POSITION.OUTSIDE_END    # 標簽位置
data_labels.font.name = 'Arial' data_labels.font.size = Pt(14) # 保存 ppt 文檔
prs.save('test.pptx')

5、散點圖

# 創建幻燈片-------------------------------------------------
prs = Presentation()    # 初始化 ppt 文檔
title_only_slide_layout = prs.slide_layouts[5]    # 選擇空白幻燈片版式
slide = prs.slides.add_slide(title_only_slide_layout)    # 添加一頁空白幻燈片
shapes = slide.shapes shapes.title.text = '散點圖'

# 定義圖表數據-------------------------------------------------
np.random.seed(42) x = np.random.randn(500) np.random.seed(2) y = np.random.randn(500) chart_data = XyChartData() # chart_data.categories = x
series = chart_data.add_series(name='高斯分布樣本') for px, py in zip(x, y): if py > 0: series.add_data_point(px, py) # 添加圖表-------------------------------------------------
left, top, width, height = Inches(0.5), Inches(1.5), Inches(9), Inches(6) graphic_frame = shapes.add_chart(chart_type=XL_CHART_TYPE.XY_SCATTER,  # 圖表類型
                                 x=left, y=top,    # 圖表區的位置
                                 cx=width, cy=height,    # 圖表的寬和高
                                 chart_data=chart_data) # 保存 ppt 文檔
prs.save('test.pptx')
