पाई चार्ट एक वृत्ताकार सांख्यिकीय ग्राफिक होता है, जिसे संख्यात्मक अनुपात को दर्शाने के लिए स्लाइस में विभाजित किया जाता है। पाई चार्ट में, प्रत्येक स्लाइस की चाप की लंबाई उसके द्वारा दर्शाई गई मात्रा के समानुपाती होती है।
उदाहरण
# 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()
