matplotlib模块（绘图模块）使用——007_image图片

代码：

import matplotlib.pyplot as plt
import numpy as np

a=np.array([0.313660827978,0.256412365412,0.659875623512,
            0.423651258935,0.169842654123,0.259861354987,
            0.412365987456,0.736598254698,0.536984563211]).reshape(3,3)
plt.imshow(a,interpolation = 'nearest',cmap='bone',origin = 'upper')   #interpolation设置不同的形状
plt.colorbar(shrink=0.9)         #设置颜色渐变条colorbar

plt.xticks(())
plt.yticks(())
plt.show()
