QST: How to plot hist not in stacked style for different columns by df.plot.hist()?
-  I have searched the [[pandas] tag](https://stackoverflow.com/questions/tagged/pandas) on StackOverflow for similar questions.

- I have asked my usage related question on [StackOverflow](https://stackoverflow.com).

When using pd.plot.hist(), how to plot different columns in the parallel style(1st pic below), rather than in the stacked style(2nd pic below)?

Thanks,
Alex
