Not the best way to use a stacked bar chart as it is meant to show the composition of a particular category.

Breaking it down: X-axis shows coffee type and Y-axis shows consumption %

However, with the use of a stacked bar you are implying that the Y-axis is also showing % of ingredients used in each coffee type: So is long black/Americano ~12% water and 8% espresso? What is the remaining 80%?

TLDR: Incorrect chart type used but interesting info none the less!
