Another example is:
Example:
from matplotlib import pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_axes([0,0,1,1])
ax.axis('equal')
subjects = ["Eng","Maths","Science","SSt","2nd Lang","Computers"]
marks = [23, 45, 34, 41,13,49]
ax.pie(marks, labels = subjects,autopct='%1.2f%%')
plt.show()
Output:
Maths
Science 21.95%
Eng
16.59%
11.22%
20.00%
23.90%
SSt
6.34% Computers
2nd Lang
Plotting a Scatter Chart
Scatter plots use dots to display values from two variables in a graph .It is used to plot data which has no
continuity(non continuous data). This allows us to see if there is any relationship or correlation between the two
variables.
Matplotlib uses a built-in function - scatter() to create scatterplots.
Example:
import matplotlib.pyplot as plt
