Creating a Simple Donut Chart
Creating a Donut Chart involves three simple steps which are as follows :
- Create a Pie Chart
- Draw a circle of suitable dimensions.
- Add circle at the Center of Pie chart
Python3
import matplotlib.pyplot as plt# Setting labels for items in ChartEmployee = ['Roshni', 'Shyam', 'Priyanshi', 'Harshit', 'Anmol']# Setting size in Chart based on # given valuesSalary = [40000, 50000, 70000, 54000, 44000]# colorscolors = ['#FF0000', '#0000FF', '#FFFF00', '#ADFF2F', '#FFA500']# explosionexplode = (0.05, 0.05, 0.05, 0.05, 0.05)# Pie Chartplt.pie(Salary, colors=colors, labels=Employee, autopct='%1.1f%%', pctdistance=0.85, explode=explode)# draw circlecentre_circle = plt.Circle((0, 0), 0.70, fc='white')fig = plt.gcf()# Adding Circle in Pie chartfig.gca().add_artist(centre_circle)# Adding Title of chartplt.title('Employee Salary Details')# Displaying Chartplt.show() |
Output:
Donut Chart using Matplotlib in Python
Prerequisites: Pie Chart in matplotlib
Donut charts are the modified version of Pie Charts with the area of center cut out. A donut is more concerned about the use of area of arcs to represent the information in the most effective manner instead of Pie chart which is more focused on comparing the proportion area between the slices. Donut charts are more efficient in terms of space because the blank space inside the donut charts can be used to display some additional information about the donut chart.
For being a Donut chart it must be necessarily a Pie chart. If we look at the pie chart, we will focus on the center of the chart. Donut charts, on the other hand, eliminates the need to compare the size or area of the slice and shifts the focus on the length of the arc, which in turn is easy to measure.
