Housemate found this while dumpster-diving. I have never, ever seen an espresso machine whose pressure gauge has no units on the dial before! I mean, what's the point in having a dial you can't read the values from? I wonder if someone asked an AI to design a pressure dial for them...

Seems pretty self explanatory. You got light, medium, and dark, and for each one you've got least to most...I can work with that.

This makes much more sense that having numerical markers. It shows you through gradations how dark it will be. A coffee shop isn’t a lab where scientifically specific numbers are necessary, you have to get the coffee out the door and this is a great solution.

The black bar is most likely a 3 to 10 bar range.

division should come at equal thirds or quarters of the total range. Its most likely thirds, as most machines arent built to handle pressure

Based on the color gradient id go with 0-3..altho im not sure what the upper 3rd would be used for as “espresso range” is over the darker grey.

Steaming milk of various thicknesses of cream? Again as you say it appears the range ends far below the upper pressure range, however, so it seems unlikely/unnecessary
