import numpy
import matplotlib.pyplot as pyplot

def draw_fig():

count = 100
xArr = [i for i in range(count)]
yArr = numpy.random.random(count)

pyplot.axes(xlim=(0, count), ylim=(0, 1))
pyplot.plot(xArr, yArr, color="b")

pyplot.xlabel("x")
pyplot.ylabel("y")

pyplot.savefig("myfig.png")
pyplot.clf()
