面积图与折线图相似，只是在绘制的线下面的区域被填充。通过将分组设置为“标准”、“堆叠”或“百分比堆叠”，可以获得不同的面积图；默认值为“标准”。
from openpyxl import Workbook from openpyxl.chart import ( AreaChart, Reference, Series, ) wb = Workbook() ws = wb.active rows = [ ['Number', 'Batch 1', 'Batch 2'], [2, 40, 30], [3, 40, 25], [4, 50, 30], [5, 30, 10], [6, 25, 5], [7, 50, 10], ] for row in rows: ws.append(row) chart = AreaChart() chart.title = "Area Chart" chart.style = 13 chart.x_axis.title = 'Test' chart.y_axis.title = 'Percentage' cats = Reference(ws, min_col=1, min_row=1, max_row=7) data = Reference(ws, min_col=2, min_row=1, max_col=3, max_row=7) chart.add_data(data, titles_from_data=True) chart.set_categories(cats) ws.add_chart(chart, "A10") wb.save("area.xlsx")也可以创建三维面积图
from openpyxl import Workbook from openpyxl.chart import ( AreaChart3D, Reference, Series, ) wb = Workbook() ws = wb.active rows = [ ['Number', 'Batch 1', 'Batch 2'], [2, 30, 40], [3, 25, 40], [4 ,30, 50], [5 ,10, 30], [6, 5, 25], [7 ,10, 50], ] for row in rows: ws.append(row) chart = AreaChart3D() chart.title = "Area Chart" chart.style = 13 chart.x_axis.title = 'Test' chart.y_axis.title = 'Percentage' chart.legend = None cats = Reference(ws, min_col=1, min_row=1, max_row=7) data = Reference(ws, min_col=2, min_row=1, max_col=3, max_row=7) chart.add_data(data, titles_from_data=True) chart.set_categories(cats) ws.add_chart(chart, "A10") wb.save("area3D.xlsx")这将生成一个简单的三维面积图，其中第三个轴可用于放置图例：
