法律研究Python - 使用 XlsxWriter 模組在 Excel 表格中繪製餅狀圖
餅狀圖是一種圓形的統計圖形，它被分成多個扇形來表示數值比例。在餅狀圖中，每個扇形的弧長與其表示的數值成正比。
示例
# import xlsxwriter module
import xlsxwriter
# Workbook() takes one, non-optional, argument which is the filename #that we want to create.
workbook = xlsxwriter.Workbook('chart_pie.xlsx')
# The workbook object is then used to add new worksheet via the #add_worksheet() method.
worksheet = workbook.add_worksheet()
# Create a new Format object to formats cells in worksheets using #add_format() method .
# here we create bold format object .
bold = workbook.add_format({'bold': 1})
# create a data list .
headings = ['Category', 'Values']
data = [
['Apple', 'Cherry', 'Pecan'],
[60, 30, 10],
]
# Write a row of data starting from 'A1' with bold format.
worksheet.write_row('A1', headings, bold)
# Write a column of data starting from A2, B2, C2 respectively.
worksheet.write_column('A2', data[0])
worksheet.write_column('B2', data[1])
# Create a chart object that can be added to a worksheet using #add_chart() method.
# here we create a pie chart object .
chart1 = workbook.add_chart({'type': 'pie'})
# Add a data series to a chart using add_series method.
# Configure the first series.
#[sheetname, first_row, first_col, last_row, last_col].
chart1.add_series({
'name': 'Pie sales data',
'categories': ['Sheet1', 1, 0, 3, 0],
'values': ['Sheet1', 1, 1, 3, 1],
})
# Add a chart title
chart1.set_title({'name': 'Popular Pie Types'})
# Set an Excel chart style. Colors with white outline and shadow.
chart1.set_style(10)
# Insert the chart into the worksheet(with an offset).
# the top-left corner of a chart is anchored to cell C2.
worksheet.insert_chart('C2', chart1, {'x_offset': 25, 'y_offset': 10})
# Finally, close the Excel file via the close() method.
workbook.close()
