In this tutorial, we are going to learn how to add an arrow to a plot? Matplotlib has provided an inbuilt function for plotting an arrow matplotlib.pyplot.arrow().

The following example illustrates the implementation and use of the Arrow.

# Arrow starting from origin
# head dimension 1x0.05
# Arrow tip point :(x,y) = (0.5,0.5)
matplotlib.pyplot.arrow(0, 0, 0.5, 0.5, head_width=0.05, head_length=0.1)

Python code for arrow in plotting

import matplotlib.pyplot as plt

plt.figure()
plt.arrow(0, 0, 0.5, 0.5, head_width=0.05, head_length=0.1)
plt.title('arrow from origin')
plt.show()

plt.figure()
plt.arrow(0, 0.6, 0.5, 0.2, head_width=0.05, head_length=0.1)
plt.title('arrow from y axis')
plt.show()

plt.figure()
plt.arrow(0.6, 0, 0.2, 0.5, head_width=0.05, head_length=0.1)
plt.title('arrow from x axis')
plt.show()

plt.figure()
plt.arrow(10, 14, 7, 9, head_width=0.5, head_length=1)
plt.xlim(0,20)
plt.ylim(0,30)
plt.title('arrow in middle space')
plt.show()

Output:

Output is as figure
