[Matplotlib-users] How to add number near point of scatter plot?

[Zhu, S. <zhu...@gm...>]

How to add number near point of scatter plot?
e.g. I have two point 1 is (1,3) and point 2 (2,4), how can I add 1
and 2 to scatter plot near these two points? Thanks!

import matplotlib.pyplot as plt
x = [1,2]
y = [3,4]
plt.scatter(x, y)
plt.show()

See
plt.text
and 
plt.annotate

See http://matplotlib.org/users/annotations_guide.html and references therein.

Hi Sterling, thank you,
I tried plt.text and it works! It seems text() does not support list input,
and I have to write loop to print the number one by one.
