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

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
