Step by Step Draw Boy Using Matplotlib Module

In this blog, we will draw boy using Matplotlib module. We will also draw, a boy is feeling loved with someone.

Created by Nutan

Import modules

import matplotlib.pyplot as plt
from numpy import sin, cos, pi, linspace

Create a figure

Create figure and write figure size according to your choice. In this example i am using figure size(18,7) and setting x limit and y limit.

plt.figure(figsize = (18, 7))
plt.xlim(-5, 5)
plt.ylim(-5, 5)
plt.gca().set_aspect('equal')
plt.show()

Output:

Draw face

We have to draw full circle for face. Angle will start from 0*pi and it will go upto 2*pi.

plt.figure(figsize = (18, 7))
#face
angles = linspace(0 * pi, 2 * pi, 100 )
r = 1.2
xs = r * cos(angles)
ys = r * sin(angles)
plt.plot(xs, ys, color = 'black')
plt.xlim(-5, 5)
plt.ylim(-5, 5)
plt.gca().set_aspect('equal')
plt.show()

Output:

Face is showing in middle, we have to move up, so that we can get place for body and legs. Circle is drawing from origin(0, 0). To move up circle, we have to add value in y.

Move face up

plt.figure(figsize = (18, 7))
#face
angles = linspace(0 * pi, 2 * pi, 100 )
r = 1.2
xs = r * cos(angles)
ys = r * sin(angles)
plt.plot(xs, ys + 2, color = 'black')
plt.xlim(-5, 5)
plt.ylim(-5, 5)
plt.gca().set_aspect('equal')
plt.show()

Output:

Draw mouth

For mouth, we have to draw half circle. Angle will start from pi and it will go upto 2*pi.

plt.figure(figsize = (18, 7))
#face
angles = linspace(0 * pi, 2 * pi, 100 )
r = 1.2
xs = r * cos(angles)
ys = r * sin(angles)
plt.plot(xs, ys + 2, color = 'black')
#mouth
mouth_angles = linspace(pi, 2 * pi, 50 )
r1 = 0.5
mouth_xs = r1 * cos(mouth_angles) 
mouth_ys = r1 * sin(mouth_angles)
plt.plot(mouth_xs, mouth_ys, color = 'red')
plt.xlim(-5, 5)
plt.ylim(-5, 5)
plt.gca().set_aspect('equal')
plt.show()

Output:

We can see, mouth is not at correct place. Let us move up.

Move mouth up

plt.figure(figsize = (18, 7))
#face
angles = linspace(0 * pi, 2 * pi, 100 )
r = 1.2
xs = r * cos(angles)
ys = r * sin(angles)
plt.plot(xs, ys + 2, color = 'black')
#mouth
mouth_angles = linspace(pi, 2 * pi, 50 )
r1 = 0.5
mouth_xs = r1 * cos(mouth_angles) 
mouth_ys = r1 * sin(mouth_angles)
plt.plot(mouth_xs, mouth_ys + 1.75, color = 'red')
plt.xlim(-5, 5)
plt.ylim(-5, 5)
plt.gca().set_aspect('equal')
plt.show()

Output:

plt.xlim(-5, 5)
plt.ylim(-5, 5)
plt.gca().set_aspect('equal')
plt.show()
