Python | Plotting charts in excel sheet using openpyxl module | Set - 1

Last Updated : 04 Jul, 2022

Prerequisite: Reading & Writing to excel sheet using openpyxl Openpyxl is a Python library using which one can perform multiple operations on excel files like reading, writing, arithmetic operations and plotting graphs. Let's see how to plot different 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 class( i.e BarChart, LineChart etc.). After creating chart objects, insert data in it and lastly, add that chart object in the sheet object.

Code #1 : Plot the Bar Chart For plotting the bar chart on an excel sheet, use BarChart class from openpyxl.chart submodule.

Python3

# import openpyxl module
import openpyxl

# import BarChart class from openpyxl.chart sub_module
from openpyxl.chart import BarChart,Reference

# Call a Workbook() function of openpyxl 
# to create a new blank Workbook object
wb = openpyxl.Workbook()

# Get workbook active sheet 
# from the active attribute.
sheet = wb.active

# write o to 9 in 1st column of the active sheet
for i in range(10):
    sheet.append([i])

# create data for plotting
values = Reference(sheet, min_col = 1, min_row = 1,
                         max_col = 1, max_row = 10)

# Create object of BarChart class
chart = BarChart()

# adding data to the Bar chart object
chart.add_data(values)

# set the title of the chart
chart.title = " BAR-CHART "

# set the title of the x-axis
chart.x_axis.title = " X_AXIS "

# set the title of the y-axis
chart.y_axis.title = " Y_AXIS "

# add chart to the sheet
# the top-left corner of a chart
# is anchored to cell E2 .
sheet.add_chart(chart, "E2")

# save the file
wb.save("barChart.xlsx")

Output: Code #2 : Plot the 3D Bar Chart For plotting the 3D bar chart on an excel sheet, use BarChart3D class from openpyxl.chart submodule.

Python3

# import openpyxl module
import openpyxl

# import BarChart3D class from openpyxl.chart sub_module
from openpyxl.chart import BarChart3D,Reference

# write o to 9 in 1st column of the active sheet
for i in range(10):
    sheet.append([i])

values = Reference(sheet, min_col = 1, min_row = 1,
                         max_col = 1, max_row = 10)

# Create object of BarChart3D class
chart = BarChart3D()

chart.add_data(values)

# set the title of the chart
chart.title = " BAR-CHART3D "

# set the title of the x-axis
chart.x_axis.title = " X AXIS "

# set the title of the y-axis
chart.y_axis.title = " Y AXIS "

# add chart to the sheet
# the top-left corner of a chart
# is anchored to cell E2.
sheet.add_chart(chart, "E2")

# save the file
wb.save("BarChart3D.xlsx")

Output: Code #3 : Plot the Area Chart For plotting the Area chart on an excel sheet, use AreaChart class from openpyxl.chart submodule.

Python3

import openpyxl

# import AreaChart class from openpyxl.chart sub_module
from openpyxl.chart import AreaChart,Reference


wb = openpyxl.Workbook()
sheet = wb.active

# write o to 9 in 1st column of the active sheet
for i in range(10):
    sheet.append([i])

values = Reference(sheet, min_col = 1, min_row = 1,
                         max_col = 1, max_row = 10)

# create object of AreaChart class
chart = AreaChart()

chart.add_data(values)

# set the title of the chart
chart.title = " AREA-CHART "

# set the title of the x-axis
chart.x_axis.title = " X-AXIS "

# set the title of the y-axis
chart.y_axis.title = " Y-AXIS "

# add chart to the sheet
# the top-left corner of a chart
# is anchored to cell E2 .
sheet.add_chart(chart, "E2")

# save the file
wb.save("AreaChart.xlsx")

Output: Code #4 : Plot the 3D Area Chart For plotting the 3D Area chart on an excel sheet, use AreaChart3D class from openpyxl.chart submodule.

Python3

import openpyxl

# import AreaChart3D class from openpyxl.chart sub_module
from openpyxl.chart import AreaChart3D,Reference

wb = openpyxl.Workbook()
sheet = wb.active

# write o to 9 in 1st column of the active sheet
for i in range(10):
    sheet.append([i])

values = Reference(sheet, min_col = 1, min_row = 1,
                         max_col = 1, max_row = 10)

# Create object of AreaChart3D class
chart = AreaChart3D()

chart.add_data(values)

# set the title of the chart
chart.title = " AREA-CHART3D "

# set the title of the x-axis
chart.x_axis.title = " X-AXIS "

# set the title of the y-axis
chart.y_axis.title = " Y-AXIS "

# add chart to the sheet
# the top-left corner of a chart
# is anchored to cell E2 .
sheet.add_chart(chart, "E2")

# save the file
wb.save("AreaChart3D.xlsx")

Output: Code #5 : Plot a Line Chart. For plotting the Line chart on an excel sheet, use LineChart class from openpyxl.chart submodule.

Python3

# import openpyxl module
import openpyxl

# import LineChart class from openpyxl.chart sub_module
from openpyxl.chart import LineChart,Reference

wb = openpyxl.Workbook()
sheet = wb.active

# write o to 9 in 1st column of the active sheet
for i in range(10):
    sheet.append([i])

values = Reference(sheet, min_col = 1, min_row = 1,
                         max_col = 1, max_row = 10)

# Create object of LineChart class
chart = LineChart()

chart.add_data(values)

# set the title of the chart
chart.title = " LINE-CHART "

# set the title of the x-axis
chart.x_axis.title = " X-AXIS "

# set the title of the y-axis
chart.y_axis.title = " Y-AXIS "

# add chart to the sheet
# the top-left corner of a chart
# is anchored to cell E2 .
sheet.add_chart(chart, "E2")

# save the file
wb.save("LineChart.xlsx")

Output: Code #6 : Plot a 3D Line Chart. For plotting the 3D Line chart on an excel sheet we have to use LineChart3D class from openpyxl.chart submodule.

Python3

import openpyxl

# import LineChart3D class from openpyxl.chart sub_module
from openpyxl.chart import LineChart3D,Reference

wb = openpyxl.Workbook()
sheet = wb.active

# write o to 9 in 1st column of the active sheet
for i in range(10):
    sheet.append([i])

values = Reference(sheet, min_col = 1, min_row = 1,
                         max_col = 1, max_row = 10)

# Create object of LineChart3D class
chart = LineChart3D()

chart.add_data(values)

# set the title of the chart
chart.title = " LINE-CHART3D "


# set the title of the x-axis
chart.x_axis.title = " X-AXIS "

# set the title of the y-axis
chart.y_axis.title = " Y-AXIS "

# add chart to the sheet
# the top-left corner of a chart
# is anchored to cell E2 .
sheet.add_chart(chart, "E2")

# save the file
wb.save("LineChart3D.xlsx")
