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.
# import openpyxl module import openpyxl
# import BubbleChart, Reference, Series class # from openpyxl.chart sub_module from openpyxl.chart import BubbleChart, Reference, Series
# 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
rows = [
("Number of Products", "Sales in USD", "Market share"),
( 14 , 12200 , 15 ),
( 20 , 60000 , 33 ),
( 18 , 24400 , 10 ),
( 22 , 32000 , 42 ),
] # write content of each row in 1st, 2nd and 3rd # column of the active sheet respectively. for row in rows:
sheet.append(row)
# Create object of BubbleChart class chart = BubbleChart()
# create data for plotting 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 )
# create a 1st series of data series = Series(values = yvalues, xvalues = xvalues,
zvalues = size, title = " 2013 ")
# add series data to the chart object chart.series.append(series) # set the title of the chart chart.title = " BUBBLE - 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("bubbleChart.xlsx") |
