Area charts are similar to line charts with the addition that the area underneath the plotted line is filled. Different variants are available by setting the grouping to “standard”, “stacked” or “percentStacked”; “standard” is the default.

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")

3D 区域图表 ¶

You can also create 3D area charts

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")

This produces a simple 3D area chart where the third axis can be used to replace the legend:

"Sample 3D area chart with a series axis"
