matplotlib legend under plot code example
Example 1: 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 2: matplotlib legend out of plot
ax.legend(loc='upper center', bbox_to_anchor=(0.5, 1.05),
ncol=3, fancybox=True, shadow=True)
Example 3: ax.legend place legend outside plot
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_axes((0.1,0.4,0.5,0.5))
ax.plot(x1,y1,linestyle='-',label='one')
ax.plot(x1,y2,linestyle='--',label='two')
ax.plot(x1,y3,linestyle='dotted',label='three')
ax.legend(bbox_to_anchor=(1.05,1.0),loc='best')
fig.savefig('Figure1.pdf')
Example 4: legend matplotlib
import matplotlib.pyplot as plt
plt.plot(x,ysin,label='sin(x)')
plt.legend()
plt.show()
