对python中Matplotlib的坐标轴的坐标区间的设定实例讲解

<span style="font-family: Arial, Helvetica, sans-serif;">>>> import numpy as np</span> 

>>> import matplotlib.pyplot as plt
>>> x=np.arange(-5,5,0.01)
>>> y=x**3
>>> plt.axis([-6,6,-10,10])
[-6, 6, -10, 10]
>>> plt.plot(x,y)
[<matplotlib.lines.Line2D object at 0x03C642B0>]
>>> plt.show()

xlim((xmin,max)) #设置坐标轴的最大最小区间 
xlim(xmin,xmax) #设置坐标轴的最大最小区间 
ylim((ymin,ymax))#设置坐标轴的最大最小区间 
ylim(ymin,ymax) #设置坐标轴的最大最小区间 

>>> import numpy as np 
>>> import matplotlib.pyplot as plt 
>>> x=np.arange(-5,5,0.01) 
>>> y=x**3 
>>> plt.xlim(-6,6) 
(-6, 6) 
>>> plt.ylim(-500,500) 
(-500, 500) 
>>> plt.plot(x,y)
