plt.subplots_adjust(left=None, bottom=None, right=None, top=None,
                wspace=None, hspace=None)12
left  = 0.125  # the left side of the subplots of the figure
right = 0.9    # the right side of the subplots of the figure
bottom = 0.1   # the bottom of the subplots of the figure
top = 0.9      # the top of the subplots of the figure
wspace = 0.2   # the amount of width reserved for blank space between subplots,
               # expressed as a fraction of the average axis width
hspace = 0.2   # the amount of height reserved for white space between subplots,
               # expressed as a fraction of the average axis height

共享坐标轴

当你通过pyplot.subplot()、pyplot.axes()函数或者Figure.add_subplot()、Figure.add_axes()方法创建一个Axes时，你可以通过sharex关键字参数传入另一个Axes表示共享X轴；或者通过sharey关键字参数传入另一个Axes表示共享Y轴。共享轴线时，当你缩放某个Axes时，另一个Axes也跟着缩放。

fig =plt.figure()
ax1 =fig.add_subplot(211)
ax1.plot([1,2,3,4,5])
ax2 =fig.add_subplot(212,sharex=ax1)
ax2.plot([7,6,5,4,3,2,1])
