ax = dftrain_raw['Survived'].value_counts().plot(kind = 'bar', figsize = (12,8),fontsize=15,rot = 0) ax.set_ylabel('Counts',fontsize = 15) ax.set_xlabel('Survived',fontsize = 15) plt.show() 12345
dftrain_raw是DataFrame类型，通过上面的命令就可以绘制柱状统计图。
kind = 'hist':绘制直方图dftrain_raw.query('Survived == 1')['Age'].plot(kind = 'density', figsize = (12,8),fontsize=15),这样可以绘制概率密度曲线参考源：https://github.com/lyhue1991/eat_tensorflow2_in_30_days
