need to have inline plots visuals on zeppelin ..

[Handys1]

used the code as below
fig, axs = plt.subplots(1, 4, figsize=(16, 4))
hdf_filled.cols['Parch'].hist(ax=axs[0])
hdf_filled.cols['SibSp'].hist(ax=axs[1])
hdf_filled.cols['Age'].boxplot(ax=axs[2], k=3)
hdf_filled.cols['Fare'].boxplot(ax=axs[3], k=3)
plt.show()

the plots are shown on the popup windows rather than inline.
