import numpy as np
import matplotlib.pyplot as plt

# Make some fake data.
a = b = np.arange(0, 3, .02)
c = np.exp(a)
d = c[::-1]

# Create plots with pre-defined labels.
plt.plot(a, c, 'k--', label='Model length')
plt.plot(a, d, 'k:', label='Data length')
plt.plot(a, c + d, 'k', label='Total message length')

legend = plt.legend(loc='upper center', title='Test', shadow=True, fontsize='x-large')

# Put a nicer background color on the legend.
legend.get_frame().set_facecolor('#00FFCC')
legend.get_title().set_fontsize(fontsize = 20)
# 不僅可以設置字體大小，還可以設置什么字體侥涵，因為legend.get_title()返回的是一個'Text'屬性
# 的對像，時刻不要忘記Matplotlib面向對像的畫圖方式啊

python matplotlib繪圖設置坐標軸刻度务豺、文本
