Python - Plotting Pie charts in excel sheet using XlsxWriter module

PythonServer Side ProgrammingProgramming

A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice, is proportional to the quantity it represents.


# 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].
   '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.
# 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.
