python matplotlib绘图设置坐标轴刻度、文本
http://blog.csdn.net/fortware/article/details/51934814
from pylab import *
from matplotlib.ticker import MultipleLocator, FormatStrFormatter

ax = subplot(111) #注意:一般都在ax中设置,不再plot中设置
plot(t,s,'--b*')
#设置主刻度标签的位置,标签文本的格式
ax.xaxis.set_major_locator(xmajorLocator)
ax.xaxis.set_major_formatter(xmajorFormatter)
ax.yaxis.set_major_locator(ymajorLocator)
