Revenue histogram with stacked bars

The New York Stock exchange firm thought your previous histogram provided great insight into how the revenue of the firms they are looking at is distributed.

However, like before, they are interested in learning a bit more about how the industry of the firms could shed more light on what is happening.

Your task is to re-create the histogram of company revenues, as before, but include the specified colors based on the list of industries given below.

There is a revenues DataFrame already loaded for your use.

Industry-color RGB definitions:

  • Tech = 124, 250, 120
  • Oil = 112,128,144
  • Pharmaceuticals = 137, 109, 247
  • Professional Services = 255, 0, 0
Instructions
