python画图

1、直线

import matplotlib.pyplot as plt
plt.plot([1,2,2.5])
plt.ylabel('some numbers')
plt.xlabel('x axis')
plt.show()

2、中文乱码

# encoding: utf-8
from matplotlib.font_manager import FontProperties
from pylab import *
x = [2,4,6,8,10]
y = [1224,838,632,626,624]
font = FontProperties(fname=r"C:WindowsFontsSimSun.ttc", size=14)
xlabel(u"text for x轴" ,fontproperties=font)
ylabel(u"text for y轴" ,fontproperties=font)
title(u"x轴和Y轴对应关系" ,fontproperties=font)
plot(x,y)
savefig('test')
show()
