pip install XlsxWriter顯示已經安裝好,所以不用重複安裝

代碼1:繪製簡單的柱形圖。

要在excel工作表上繪製簡單的柱形圖,請使用add_chart()方法和工作簿對象的“ column”關鍵字參數類型。

上代碼:

<code># import xlsxwriter module 
import xlsxwriter 
	
# Workbook() takes one, non-optional, argument 
# which is the filename that we want to create. 
workbook = xlsxwriter.Workbook('chart_column.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 = ['Number', 'Batch 1', 'Batch 2'] 
	
data = [ 
	[2, 3, 4, 5, 6, 7], 
	[80, 80, 100, 60, 50, 100], 
	[60, 50, 60, 20, 10, 20], 
] 
	
# 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]) 
worksheet.write_column('C2', data[2]) 
	
# Create a chart object that can be added 
# to a worksheet using add_chart() method. 
	
# here we create a column chart object . 
chart1 = workbook.add_chart({'type': 'column'}) 
	
# Add a data series to a chart 
# using add_series method. 
	
# Configure the first series. 
# = Sheet1 !$A$1 is equivalent to ['Sheet1', 0, 0]. 

# note : spaces is not inserted in b / w 
# = and Sheet1, Sheet1 and ! 
# if space is inserted it throws warning. 
chart1.add_series({ 
	'name':	 '= Sheet1 !$B$1', 
	'categories': '= Sheet1 !$A$2:$A$7', 
	'values':	 '= Sheet1 !$B$2:$B$7', 
}) 
	
# Configure a second series. 
# Note use of alternative syntax to define ranges. 
# [sheetname, first_row, first_col, last_row, last_col]. 
chart1.add_series({ 
	'name':	 ['Sheet1', 0, 2], 
	'categories': ['Sheet1', 1, 0, 6, 0], 
	'values':	 ['Sheet1', 1, 2, 6, 2], 
}) 
	
# Add a chart title 
chart1.set_title ({'name': 'Results of data analysis'}) 
	
# Add x-axis label 
chart1.set_x_axis({'name': 'Test number'}) 
	
# Add y-axis label 
chart1.set_y_axis({'name': 'Data length (mm)'}) 
	
# Set an Excel chart style. 
chart1.set_style(11) 
	
# add chart to the worksheet 
# the top-left corner of a chart 
# is anchored to cell E2 . 
worksheet.insert_chart('E2', chart1) 
	
# Finally, close the Excel file 
# via the close() method. 
workbook.close()

代碼2:繪製堆積柱形圖.

要在Excel工作表上繪製堆積柱形圖,請使用add_chart()方法,其類型為工作簿對象的“ column”和子類型“ stacked”關鍵字參數。

上代碼演示:

<code># import xlsxwriter module 
import xlsxwriter 
	
# Workbook() takes one, non-optional, argument 
# which is the filename that we want to create. 
workbook = xlsxwriter.Workbook('chart_column2.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 = ['Number', 'Batch 1', 'Batch 2'] 
	
data = [ 
	[2, 3, 4, 5, 6, 7], 
	[80, 80, 100, 60, 50, 100], 
	[60, 50, 60, 20, 10, 20], 
] 
	
# 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]) 
worksheet.write_column('C2', data[2]) 
	
# Create a chart object that can be added 
# to a worksheet using add_chart() method. 
	
# here we create a stacked Column chart object . 
chart1 = workbook.add_chart({'type': 'column', 'subtype': 'stacked'}) 
	
# Add a data series to a chart 
# using add_series method. 
	
# Configure the first series. 
# = Sheet1 !$A$1 is equivalent to ['Sheet1', 0, 0]. 
chart1.add_series({ 
	'name':	 '= Sheet1 !$B$1', 
	'categories': '= Sheet1 !$A$2:$A$7', 
	'values':	 '= Sheet1 !$B$2:$B$7', 
}) 
	
# Configure a second series. 
# Note use of alternative syntax to define ranges. 
# [sheetname, first_row, first_col, last_row, last_col]. 
chart1.add_series({ 
	'name':	 ['Sheet1', 0, 2], 
	'categories': ['Sheet1', 1, 0, 6, 0], 
	'values':	 ['Sheet1', 1, 2, 6, 2], 
}) 
	
# Add a chart title 
chart1.set_title ({'name': 'Results of data analysis'}) 
	
# Add x-axis label 
chart1.set_x_axis({'name': 'Test number'}) 
	
# Add y-axis label 
chart1.set_y_axis({'name': 'Data length (mm)'}) 
	
# Set an Excel chart style. 
chart1.set_style(11) 
	
# add chart to the worksheet 
# the top-left corner of a chart 
# is anchored to cell E2 . 
worksheet.insert_chart('E2', chart1) 
	
# Finally, close the Excel file 
# via the close() method. 
workbook.close()

代碼3:繪製堆積柱形圖百分比.

若要在Excel工作表上繪製“堆積百分比”圖表,請使用add_chart()方法,其類型為工作簿對象的“列”類型和子類型“ percent_stacked”關鍵字參數。

<code># import xlsxwriter module 
import xlsxwriter 
	
# Workbook() takes one, non-optional, argument 
# which is the filename that we want to create. 
workbook = xlsxwriter.Workbook('chart_column3.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 = ['Number', 'Batch 1', 'Batch 2'] 
	
data = [ 
	[2, 3, 4, 5, 6, 7], 
	[80, 80, 100, 60, 50, 100], 
	[60, 50, 60, 20, 10, 20], 
] 
	
# 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]) 
worksheet.write_column('C2', data[2]) 
	
# Create a chart object that can be added 
# to a worksheet using add_chart() method. 
	
# here we create a percent stacked Column chart object . 
chart1 = workbook.add_chart({'type': 'column', 'subtype': 'percent_stacked'}) 
	
# Add a data series to a chart 
# using add_series method. 
	
# Configure the first series. 
# = Sheet1 !$A$1 is equivalent to ['Sheet1', 0, 0]. 
chart1.add_series({ 
	'name':	 '= Sheet1 !$B$1', 
	'categories': '= Sheet1 !$A$2:$A$7', 
	'values':	 '= Sheet1 !$B$2:$B$7', 
}) 
	
# Configure a second series. 
# Note use of alternative syntax to define ranges. 
# [sheetname, first_row, first_col, last_row, last_col]. 
chart1.add_series({ 
	'name':	 ['Sheet1', 0, 2], 
	'categories': ['Sheet1', 1, 0, 6, 0], 
	'values':	 ['Sheet1', 1, 2, 6, 2], 
}) 
	
# Add a chart title 
chart1.set_title ({'name': 'Results of data analysis'}) 
	
# Add x-axis label 
chart1.set_x_axis({'name': 'Test number'}) 
	
# Add y-axis label 
chart1.set_y_axis({'name': 'Data length (mm)'}) 
	
# Set an Excel chart style. 
chart1.set_style(11) 
	
# add chart to the worksheet 
# the top-left corner of a chart 
# is anchored to cell E2 . 
worksheet.insert_chart('E2', chart1) 
	
# Finally, close the Excel file 
# via the close() method. 
workbook.close()
