A quick tip for adding colour from two different sets stolen from Andy today:

  1. Build your viz (here profit vs. sales, split by product ID).
  2. Add your first set to detail.
  3. Add your second set to detail.
  4. Click on the dots for each set and add them to colour.
  5. The order of the pills does matter.

Confused? Maybe the video will help:
