How to create grid in 2D plot ?

 The minimal working example (creation of dataset + simple plot) is given below.

import matplotlib.pyplot as plt

import numpy as np

x = np.arange(0,20.01,0.01)

y = np.sin(x)

plt.figure()

plt.plot(x,y)

plt.xlabel("$x$")

plt.ylabel("$sin(x)$")

plt.xlim(0,20.0)

plt.ylim(-1.5,1.5)

plt.show()

After typing and running this code the following diagram is obtained.

Figure 1 – Result of minimal working example without the grid.

As seen from previous figure the diagram does not contain grid. To include grid just type in the following command before plt.show() command.

plt.grid(True)

When the entire code is executed the following diagram is obtained.

Figure 2 – Result of minimal working example with plt.grid(True) command included.

The entire code of minimal working example is given below.

import matplotlib.pyplot as plt

import numpy as np

x = np.arange(0,20.01,0.01)

y = np.sin(x)

plt.figure()

plt.plot(x,y)

plt.xlabel("$x$")

plt.ylabel("$sin(x)$")

plt.xlim(0,20.0)

plt.ylim(-1.5,1.5)

plt.grid(True)

plt.show()
