Python | Plotting Combined charts in excel sheet using XlsxWriter module

Prerequisite: Create and Write on an excel sheet

XlsxWriter is a Python library using which one can perform multiple operations on excel files like creating, writing, arithmetic operations and plotting graphs. Let’s see how to plot Combined charts using realtime data.

Charts are composed of at least one series of one or more data points. Series themselves are comprised of references to cell ranges. For plotting the charts on an excel sheet, firstly, create chart object of specific chart type( i.e Line, Column chart etc.). After creating chart objects, insert data in it and lastly, add that chart object in the sheet object.

Code #1 : Plot a combined column and line chart that share the same X and Y axes.
For plotting the Combined chart on an excel sheet, use combine() method of the chart object for combining Two chart objects together.

# import xlsxwriter module

# 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 .

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()

Output-1

Code #2 : Plot a combined column and line chart in which the secondary chart will have a secondary Y axis.
For plotting the Combined chart with secondary Y axis on an excel sheet, We set a secondary Y axis via 'y2_axis'. keyword argument of the add_series() method of the respective chart object .
