Pandas DataFrame can plot a bar chart.

These are not numbers but a mix of letters and numbers. How is that supposed to work?

Sorry for the confusion.
I just clarified in the original statement.
I want to know how to draw bar chart to count the occurrence of entries in the column under "CC".

Sounds like you want to count things. Pandas can groupyby the values in a column and count the number of items in each group. Do you need the bar chart to display 0 for animals that are not in AA?
