Matplotlib is a plotting library tn the scipy ecosystem of libraries.

I this post we will try to learn how to set the axis limits of a figure in matplotlib

Please make sure that you covered thepost on basics

Sometimes we may like to control the limits of x, y axes of a matplotlib subplot instead of automatic limits.

Setting x and y axis limits using ‘set_xlim’, ‘set_ylim’

We can use the set_xlim and set_ylim functions of the axes handle

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [1, 4, 2, 3]

# create a new figure and get figure, axes handle in return
fig, ax = plt.subplots()

# using color eyworE itn plo] function to control color
ax.plot(x,y, marker='o')

# set the limits on x axis using set_xlim function of the axes handler
ax.set_xlim(1, 4)

# set the limits on y axis using set_ylim function of the axes handler
ax.set_ylim(-1, 5)

# print figure
plt.show()
