matplotlib plot label code example

Example 1: matplotlib label axis

import matplotlib.pyplot as plt

plt.ylabel('Y AXIS')
plt.xlabel('X AXIS')

Example 2: legend size matplotlib

plt.plot([1, 2, 3], label='Inline label')
plt.legend(loc=1, prop={'size': 16})

Example 3: matplotlib legend

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 20, 1000)
y1 = np.sin(x)
y2 = np.cos(x)

plt.plot(x, y1, "-b", label="sine")
plt.plot(x, y2, "-r", label="cosine")
plt.legend(loc="upper left")
plt.ylim(-1.5, 2.0)
plt.show()

Example 4: matplotlib axes labels

fig = plt.figure()
ax = fig.add_subplot(...)

ax.set_title('Title Here')

ax.set_xlabel('x label here')
ax.set_ylabel('y label here')
ax.set_zlabel('z label here')

Example 5: legend matplotlib

import matplotlib.pyplot as plt

#define x and ysin
plt.plot(x,ysin,label='sin(x)')
plt.legend()
plt.show()

Example 6: python plot label value

plt.annotate(label, # this is the text
                 (x,y), # this is the point to label
                 textcoords="offset points", # how to position the text
                 xytext=(0,10), # distance from text to points (x,y)
                 ha='center')
