代碼演示：

# import xlsxwriter module import xlsxwriter # Workbook() takes one, non-optional, argument # which is the filename that we want to create. workbook = xlsxwriter.Workbook(chart_Line.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 line chart object . chart1 = workbook.add_chart({type: line}) # 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 with given # offset values at the top-left corner of # a chart is anchored to cell D2 . worksheet.insert_chart(D2, chart1, {x_offset: 25, y_offset: 10}) # Finally, close the Excel file # via the close() method. workbook.close()
