Python | Plotting charts in excel sheet using openpyxl module | Set – 2 (original) (raw)

Last Updated : 01 Jul, 2022

Prerequisite: Python | Plotting charts in excel sheet using openpyxl module | Set – 1 Openpyxl is a Python library using which one can perform multiple operations on excel files like reading, writing, arithmetic operations and plotting graphs. Charts are composed of at least one series of one or more data points. Series themselves are comprised of references to cell ranges. Let’s see how to plot Scatter, Bubble, Pie, 3D Pie Chart on an excel sheet using openpyxl. For plotting the charts on an excel sheet, firstly, create chart object of specific chart class( i.e ScatterChart, PieChart etc.). After creating chart objects, insert data in it and lastly, add that chart object in the sheet object. Let’s see how to plot different charts using realtime data. Code #1 : Plot the Bubble Chart. Bubble charts are similar to scatter charts but use a third dimension to determine the size of the bubbles. Charts can include multiple series. For plotting the bubble chart on an excel sheet, use BubbleChart class from openpyxl.chart submodule.

Python3

import openpyxl

from openpyxl.chart import BubbleChart, Reference, Series

wb = openpyxl.Workbook()

sheet = wb.active

rows = [

`` ("Number of Products", "Sales in USD", "Market share"),

`` ( 14 , 12200 , 15 ),

`` ( 20 , 60000 , 33 ),

`` ( 18 , 24400 , 10 ),

`` ( 22 , 32000 , 42 ),

]

for row in rows:

`` sheet.append(row)

chart = BubbleChart()

xvalues = Reference(sheet, min_col = 1 ,

`` min_row = 2 , max_row = 5 )

yvalues = Reference(sheet, min_col = 2 ,

`` min_row = 2 , max_row = 5 )

size = Reference(sheet, min_col = 3 ,

`` min_row = 2 , max_row = 5 )

series = Series(values = yvalues, xvalues = xvalues,

`` zvalues = size, title = " 2013 ")

chart.series.append(series)

chart.title = " BUBBLE - CHART "

chart.x_axis.title = " X_AXIS "

chart.y_axis.title = " Y_AXIS "

sheet.add_chart(chart, "E2")

wb.save("bubbleChart.xlsx")

Output: Code #2 : Plot the Scatter Chart Scatter, or xy charts are similar to some line charts. For plotting the Scatter chart on an excel sheet, use ScatterChart class from openpyxl.chart submodule.

Python3

import openpyxl

from openpyxl.chart import ScatterChart, Reference, Series

wb = openpyxl.Workbook()

sheet = wb.active

rows = [

`` ("Number of Products", "Sales in USD", "Market share"),

`` ( 14 , 12200 , 15 ),

`` ( 20 , 60000 , 33 ),

`` ( 18 , 24400 , 10 ),

`` ( 22 , 32000 , 42 ),

]

for row in rows:

`` sheet.append(row)

chart = ScatterChart()

xvalues = Reference(sheet, min_col = 1 ,

`` min_row = 2 , max_row = 5 )

yvalues = Reference(sheet, min_col = 2 ,

`` min_row = 2 , max_row = 5 )

size = Reference(sheet, min_col = 3 ,

`` min_row = 2 , max_row = 5 )

series = Series(values = yvalues, xvalues = xvalues,

`` zvalues = size, title = " 2013 ")

chart.series.append(series)

chart.title = " SCATTER - CHART "

chart.x_axis.title = " X_AXIS "

chart.y_axis.title = " Y_AXIS "

sheet.add_chart(chart, "E2")

wb.save(" ScatterChart.xlsx")

Output: Code #3 : Plot the Pie Chart Pie charts plot data as slices of a circle with each slice representing the percentage of the whole. Slices are plotted in a clockwise direction with 0° being at the top of the circle. Pie charts can only take a single series of data. For plotting the Pie chart on an excel sheet, use PieChart class from openpyxl.chart submodule.

Python

import openpyxl

from openpyxl.chart import PieChart, Reference

wb = openpyxl.Workbook()

sheet = wb.active

datas = [

`` [ 'Pie' , 'Sold' ],

`` [ 'Apple' , 50 ],

`` [ 'Cherry' , 30 ],

`` [ 'Pumpkin' , 10 ],

`` [ 'Chocolate' , 40 ],

]

for row in datas:

`` sheet.append(row)

chart = PieChart()

labels = Reference(sheet, min_col = 1 ,

`` min_row = 2 , max_row = 5 )

data = Reference(sheet, min_col = 2 ,

`` min_row = 1 , max_row = 5 )

chart.add_data(data, titles_from_data = True )

chart.set_categories(labels)

chart.title = " PIE - CHART "

sheet.add_chart(chart, "E2")

wb.save(" PieChart.xlsx")

Output: Code #4: Plot the Bar Chart For plotting the 3D pie chart on an excel sheet, use PieChart3D class from openpyxl.chart submodule.

Python3

import openpyxl

from openpyxl.chart import PieChart3D, Reference

wb = openpyxl.Workbook()

sheet = wb.active

datas = [

`` [ 'Pie' , 'Sold' ],

`` [ 'Apple' , 50 ],

`` [ 'Cherry' , 30 ],

`` [ 'Pumpkin' , 10 ],

`` [ 'Chocolate' , 40 ],

]

for row in datas:

`` sheet.append(row)

chart = PieChart3D()

labels = Reference(sheet, min_col = 1 ,

`` min_row = 2 , max_row = 5 )

data = Reference(sheet, min_col = 2 ,

`` min_row = 1 , max_row = 5 )

chart.add_data(data, titles_from_data = True )

chart.set_categories(labels)

chart.title = " 3DPIE - CHART "

sheet.add_chart(chart, "E2")

wb.save(" 3DPieChart .xlsx")
