法律Python——使用 XlsxWriter 模块在 Excel 表格中绘图合并图表
lsxWriter 是一个 Python 库，使用它可以在 Excel 文件中执行多个操作，如创建、写入、算术运算和绘图。
示例
# import xlsxwriter module
import xlsxwriter
# Workbook() takes one, non-optional, argument which is the filename #that we want to create.
workbook = xlsxwriter.Workbook('chart_combined.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': True})
# Add the worksheet data that the charts will refer to.
headings = ['Number', 'Batch 1', 'Batch 2']
data = [
[2, 3, 4, 5, 6, 7],
[10, 40, 50, 20, 10, 50],
[30, 60, 70, 50, 40, 30],
]
# 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.This will use as the primary #chart.
column_chart1 = workbook.add_chart({'type': 'column'})
# Add a data series to a chart using add_series method.
# Configure the first series.
# = Sheet1 !$A$1 is equivalent to ['Sheet1', 0, 0].
# note : spaces is not inserted in b/w = and Sheet1, Sheet1 and !
# if space is inserted it throws warning.
column_chart1.add_series({
'name': '= Sheet1 !$B$1',
'categories': '= Sheet1 !$A$2:$A$7',
'values': '= Sheet1 !$B$2:$B$7',
})
# Create a new line chart.This will use as the secondary chart.
line_chart1 = workbook.add_chart({'type': 'line'})
# Configure the data series for the secondary chart.
line_chart1.add_series({
'name': '= Sheet1 !$C$1',
'categories': '= Sheet1 !$A$2:$A$7',
'values': '= Sheet1 !$C$2:$C$7',
})
# Combine both column and line chatrs together.
column_chart1.combine(line_chart1)
# Add a chart title
column_chart1.set_title({ 'name': 'Combined chart - same Y axis'})
# Add x-axis label
column_chart1.set_x_axis({'name': 'Test number'})
# Add y-axis label
column_chart1.set_y_axis({'name': 'Sample length (mm)'})
# add chart to the worksheet with given offset values at the top-left #corner of a chart is anchored to cell D2
worksheet.insert_chart('D2', column_chart1, {'x_offset': 25, 'y_offset': 10})
# Finally, close the Excel file via the close() method.
workbook.close()
