How to make grouped bar charts in pandas/Python with crosstab and pivot tables and more

Building grouped bar charts in pandas can be a pain, since you need to understand how .plot() and matplotlib work *AND* get your data formatted correctly first. This video explains how .plot() works, what columns/rows do when plotting, and how to reshape or reorganize your data into a grouped-bar-chart-friendly format - we look at pivot_table, groupby + value_counts + reset_index or unstack, and crosstab. Not in-depth, but probably enough to tackle what you're trying to do!

If you're asking yourself "why are there so many bold words for index names or columns??" or "why did he have to do y='count' in that one spot???" I recommended giving a read about MultiIndexes: https://pandas.pydata.org/pandas-docs/stable/user_guide/advanced.html
