For plotting the charts on an excel sheet, firstly, create chart object of specific chart type( i.e Pie chart etc.). After creating chart objects, insert data in it and lastly, add that chart object in the sheet object. also for plotting the simple Pie chart on an excel sheet, use add_chart() method with type ‘pie’ keyword argument of a workbook object.

# 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() # here we create bold format object . bold = workbook.add_format({'bold':1}) # this is our data with data list headings = ['Category', 'Values'] data = [ ['Apple', 'Cherry', 'Banana'], [50, 40, 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]) #this is the type of chart chart1 = workbook.add_chart({'type': 'pie'}) # Add a data series to a chart chart1.add_series({ 'name':'Pie Sales Data', 'categories':['Sheet1', 1,0,3,0], 'values':['Sheet1', 1,1,3,1], }) #set the title for the chart chart1.set_title({'name':'Fruits Data Chart'}) #set the style for the chart chart1.set_style(10) #insert chart to the worksheet worksheet.insert_chart('C2', chart1, {'x_offset':25, 'y_offset':10}) #close the workbook workbook.close() |
