Python-XlsxWriterモジュールを使用してExcelシートに折れ線グラフをプロットする

折れ線グラフは、一連のデータポイントを実線で結ぶ資産の過去の価格アクションをグラフで表したものです。これは、金融で使用される最も基本的なタイプのチャートであり、通常、時間の経過に伴う証券の終値のみを示します。

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_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()
