使用Python的matplotlib模块可以很方便的将数据处理成图表,使数据更加形象、直观。
#!/usr/bin/env python
import matplotlib.pyplot as plt
import numpy as np
from mpl_toolkits.axes_grid.anchored_artists import AnchoredText
y1=np.loadtxt('ReadDataCostTime.txt')
y2=np.sort(y1)
x=np.arange(0, y1.size)
fig=plt.figure(figsize=(30, 12))
left,bottom,width,height=0.05, 0.05, 0.9, 0.9
ax1=fig.add_axes([left,bottom,width,height])
ax1.plot(x,y1,'r')
ax1.set_xlabel('period')
ax1.set_ylabel('time')
ax1.set_title('Raw Data')
at = AnchoredText("min:%.6fs\nmax:%.6fs\nsum:%.6fs\nmean:%.6fs"%(y1.min(),y1.max(),y1.sum(),y1.mean()),
prop=dict(size=20), frameon=True,
loc=9,
)
at.patch.set_boxstyle("round,pad=0.,rounding_size=0.2")
ax1.add_artist(at)
left,bottom,width,height=0.1, 0.73, 0.3, 0.25
ax2=fig.add_axes([left,bottom,width,height])
ax2.plot(x,y2,'b')
ax2.set_xlabel('period')
ax2.set_ylabel('time')
ax2.set_title('Time Distribution')
plt.legend()
plt.show()
