主要问题
1.介绍
如题，画双轴子图不能显示 x-轴坐标轴标签，似乎 “双轴”与“子图”存在冲突有关，当前版本是 anaconda 3.7.4。比较奇葩的是 我家里的电脑，3.7.3 却没这个问题。但我把公司电脑换成 3.7.3 问题依旧，崩溃。

b = [2,3,4,5,7,9,20,20,11,13,1,2,3,9,23,2,6,7,7,7]

data = pd.DataFrame({'a':a,'b':b,'c':c})
data = data.groupby(['a'])['b','c'].sum()
nrow = 2
ncol = 1
fig = plt.figure(figsize=(ncol*10,nrow*4))
ax_1 = plt.subplot2grid((nrow, ncol), (0, 0), colspan=1, rowspan=1,facecolor = 'black')
ax_2 = plt.subplot2grid((nrow, ncol), (1, 0), colspan=1, rowspan=1,facecolor = 'black')
data['b'].plot(ax = ax_1,color = 'r')
data['c'].plot(ax = ax_1.twinx(),color = 'y')

2.只画双轴，正常显示

3.只画子图，也能正常显示
