Python matplotlib generates a three-square graph of X

：

Import Matplotlib.pyplot as Plt

Import NumPy as NP

x = Np.linspace (-100,100,100)

y = x**3

Plt.figure (num=3,figsize= (8,5)) #num xuhao;figsize long width

L1=plt.plot (x, Y, ' P ') # Quta is-to-return name to Plt.legend (handles)

Plt.xlim ((-100,100))

Plt.ylim (( -100000,100000))

Plt.xlabel (' X ') #x Zhou label

Plt.ylabel (' Y ')

Ax = PLT.GCA ()

ax.spines[' right '].set_color (' none ')

ax.spines[' top '].set_color (' None ') # #don ' t display border

Ax.xaxis.set_ticks_position (' Bottom ') # #set X Zhou

Ax.yaxis.set_ticks_position (' left ')

ax.spines[' Bottom '].set_position ((' data ', 0)) #y 0 postition is x position

Ax.spines[' left '].set_position (' data ', 0)

# # #tu Li

# labels can just set one label just post one line

Plt.legend (handles=l1,labels= ' y=x**3 ', loc= ' best ') # #loc =location

Plt.show ()
