This article on Python automate the operation of Excel and generate charts, a detailed analysis and description of the

XlsxWriter is a python module for writing Excel 2007 and xlsx file formats. It can be used to write text, numbers, formulas and support for cell formatting, images, charts, document configuration, auto-filtering and other features
Benefits: more features, high fidelity documents, extended format types, faster and configurable
Cons: cannot be used to read and modify excel files

2. Generate line graphs
# -*- coding:utf-8 -*-
import xlsxwriter
# Create an excel
workbook = ("chart_line.xlsx")
# Create a sheet
worksheet = workbook.add_worksheet()
# worksheet = workbook.add_worksheet("bug_analysis")
# Custom styles, bolded
bold = workbook.add_format({'bold': 1})
# --------1, prepare data and write to excel ---------------
# Write data to excel, to be used when creating icons
headings = ['Number', 'testA', 'testB']
data = [
['2017-9-1', '2017-9-2', '2017-9-3', '2017-9-4', '2017-9-5', '2017-9-6'],
[10, 40, 50, 20, 10, 50],
[30, 60, 70, 50, 40, 30],
]
# Write to table header
worksheet.write_row('A1', headings, bold)
# Write data
worksheet.write_column('A2', data[0])
worksheet.write_column('B2', data[1])
worksheet.write_column('C2', data[2])
# --------2, generate charts and insert into excel ---------------
# Create a bar chart (line chart)
chart_col = workbook.add_chart({'type': 'line'})
# Configure the first series of data
chart_col.add_series({
# Here sheet1 is the default value, because we didn't specify a sheet name when we created the new sheet.
# If we set the sheet name when we create a new sheet, we have to set it to the appropriate value here.
'name': '=Sheet1!$B$1',
'categories': '=Sheet1!$A$2:$A$7',
'values': '=Sheet1!$B$2:$B$7',
'line': {'color': 'red'},
})
# Configure the second series of data
chart_col.add_series({
'name': '=Sheet1!$C$1',
'categories': '=Sheet1!$A$2:$A$7',
'values': '=Sheet1!$C$2:$C$7',
'line': {'color': 'yellow'},
})
# Configure the second series of data (another syntax is used)
# chart_col.add_series({
# 'name': ['Sheet1', 0, 2],
# 'categories': ['Sheet1', 1, 0, 6, 0],
# 'values': ['Sheet1', 1, 2, 6, 2],
# 'line': {'color': 'yellow'},
# })
# Set the title of the chart and the x, y axis information
chart_col.set_title({'name': 'The xxx site Bug Analysis'})
chart_col.set_x_axis({'name': 'Test number'})
chart_col.set_y_axis({'name': 'Sample length (mm)'})
# Set the style of the chart
chart_col.set_style(1)
# Insert the chart into the worksheet and set the offset
worksheet.insert_chart('A10', chart_col, {'x_offset': 25, 'y_offset': 10})

3. Generate bar charts
# -*- coding:utf-8 -*-
import xlsxwriter
# Create an excel
workbook = ("chart_column.xlsx")
# Create a sheet
worksheet = workbook.add_worksheet()
# worksheet = workbook.add_worksheet("bug_analysis")
# Custom styles, bolded
bold = workbook.add_format({'bold': 1})
# --------1, prepare data and write to excel ---------------
# Write data to excel, to be used when creating icons
headings = ['Number', 'testA', 'testB']
data = [
['2017-9-1', '2017-9-2', '2017-9-3', '2017-9-4', '2017-9-5', '2017-9-6'],
[10, 40, 50, 20, 10, 50],
[30, 60, 70, 50, 40, 30],
]
# Write to table header
worksheet.write_row('A1', headings, bold)
# Write data
worksheet.write_column('A2', data[0])
worksheet.write_column('B2', data[1])
worksheet.write_column('C2', data[2])
# --------2, generate charts and insert into excel ---------------
# Create a column chart
chart_col = workbook.add_chart({'type': 'column'})
# Configure the first series of data
chart_col.add_series({
# Here sheet1 is the default value, because we didn't specify a sheet name when we created the new sheet.
# If we set the sheet name when we create a new sheet, we have to set it to the appropriate value here.
'name': '=Sheet1!$B$1',
'categories': '=Sheet1!$A$2:$A$7',
'values': '=Sheet1!$B$2:$B$7',
'line': {'color': 'red'},
})
# Configure the second series of data (another syntax is used)
chart_col.add_series({
'name': '=Sheet1!$C$1',
'categories': '=Sheet1!$A$2:$A$7',
'values': '=Sheet1!$C$2:$C$7',
'line': {'color': 'yellow'},
})
# Configure the second series of data (another syntax is used)
# chart_col.add_series({
# 'name': ['Sheet1', 0, 2],
# 'categories': ['Sheet1', 1, 0, 6, 0],
# 'values': ['Sheet1', 1, 2, 6, 2],
# 'line': {'color': 'yellow'},
# })
# Set the title of the chart and the x, y axis information
chart_col.set_title({'name': 'The xxx site Bug Analysis'})
chart_col.set_x_axis({'name': 'Test number'})
chart_col.set_y_axis({'name': 'Sample length (mm)'})
# Set the style of the chart
chart_col.set_style(1)
# Insert charts into worksheets and offsets
worksheet.insert_chart('A10', chart_col, {'x_offset': 25, 'y_offset': 10})
()
4. Generate pie charts
# -*- coding:utf-8 -*-
import xlsxwriter
# Create an excel
workbook = ("chart_pie.xlsx")
# Create a sheet
worksheet = workbook.add_worksheet()
# Custom styles, bolded
bold = workbook.add_format({'bold': 1})
# --------1, prepare data and write to excel ---------------
# Write data to excel, to be used when creating icons
data = [
['closed', 'active', 'reopen', 'NT'],
[1012, 109, 123, 131],
]
# Write data
worksheet.write_row('A1', data[0], bold)
worksheet.write_row('A2', data[1])
# --------2, generate charts and insert into excel ---------------
# Create a bar chart (pie chart)
chart_col = workbook.add_chart({'type': 'pie'})
# Configure the first series of data
chart_col.add_series({
'name': 'Bug Analysis',
'categories': '=Sheet1!$A$1:$D$1',
'values': '=Sheet1!$A$2:$D$2',
'points': [
{'fill': {'color': '#00CD00'}},
{'fill': {'color': 'red'}},
{'fill': {'color': 'yellow'}},
{'fill': {'color': 'gray'}},
],
})
# Set the title of the chart and the x, y axis information
chart_col.set_title({'name': 'Bug Analysis'})
# Set the style of the chart
chart_col.set_style(10)
# Insert charts into worksheets and offsets
worksheet.insert_chart('B10', chart_col, {'x_offset': 25, 'y_offset': 10})
()
5. Practical development
xlswriter new and write to Excel
# 3.6.2 xlswriter new and write to Excel
def fun3_6_2():
# Create Exce and add sheets
workbook = ('')
worksheet = workbook.add_worksheet()
# Set column widths
worksheet.set_column('A:A', 20)
# Set the format
bold = workbook.add_format({'bold': True})
# Add text content
('A1', 'Hello')
# Add content by format
('A2', 'World', bold)
# Write some numbers
(2, 0, 123)
(3, 0, 123.456)
# Add a picture
worksheet.insert_image('B5', '')
