美美的matplotlib

总是感觉matplotlib画的图不是很好看，以前用highcharts画图很清新，而且自动调色，但今天在网上看到别人用matplotlib画的图，简直小清新，也发现自己菜菜的。

import numpy as np

import matplotlib.pyplot as plt



n = 12

X = np.arange(n)

Y1 = (1-X/float(n)) * np.random.uniform(0.5,1.0,n)

Y2 = (1-X/float(n)) * np.random.uniform(0.5,1.0,n)



plt.axes([0.025,0.025,0.95,0.95])

plt.bar(X, +Y1, facecolor='#9999ff', edgecolor='white')

plt.bar(X, -Y2, facecolor='#ff9999', edgecolor='white')



for x,y in zip(X,Y1):

    plt.text(x+0.4, y+0.05, '%.2f' % y, ha='center', va= 'bottom')



for x,y in zip(X,Y2):

    plt.text(x+0.4, -y-0.05, '%.2f' % y, ha='center', va= 'top')



plt.xlim(-.5,n), plt.xticks([])

plt.ylim(-1.25,+1.25), plt.yticks([])

plt.show()
