# Python - Plotting Line charts in excel sheet using XlsxWriter module

PythonServer Side ProgrammingProgramming

A line chart is a graphical representation of an asset's historical price action that connects a series of data points with a continuous line. This is the most basic type of chart used in finance and typically only depicts a security's closing prices over time.

## Example

# 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.
# Create a new Format object to formats cells in worksheets using #add_format() method .
# here we create bold format object .
# 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 .
# 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 .
# Configure the first series.= Sheet1 !$A$1 is equivalent to #['Sheet1', 0, 0].
# note : spaces is not inserted in b/w = and Sheet1, Sheet1 and !
# if space is inserted it throws warning.
'name': '= Sheet1 !$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].
'name': ['Sheet1', 0, 2],
'categories': ['Sheet1', 1, 0, 6, 0],
'values': ['Sheet1', 1, 2, 6, 2],
})
chart1.set_title ({'name': 'Results of data analysis'})
workbook.close()
