# import xlsxwriter module
import xlsxwriter
# Workbook() takes one, non-optional, argument which is the filename #that we want to create.
workbook = xlsxwriter.Workbook('chart_gradient1.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 .

]
# Write a row of data starting from 'A1'with bold format

# Create a chart object that can be added to a worksheet using #add_chart() method.
# here we create a column chart object

#Add a data series with Gradient to a chart using add_series method.
# Configure the first series. = Sheet1 !$A$1 is equivalent to #['Sheet1', 0, 0].

# if space is inserted it throws warning.

{'x_offset': 25, 'y_offset': 10})
# Finally, close the Excel file via the close() method.
