Introduction
The Y-scale on a graph represents the vertical axis, typically used to measure values such as hydrogen output, pressure, or energy over time.

🧠 What It Means
Essential for understanding trends in hydrogen production and usage.
Can show kg of H₂, efficiency %, voltage, etc.
Combined with X-scale to form plots and performance curves.
❗ Key Challenges
Bad Y-scaling distorts data interpretation.
Must be clearly labelled and consistently spaced.
Logarithmic vs. linear Y-scales can mislead if not explained.
🦁 Muzaffar’s Comment
“Y-scale is the difference between insight and confusion — label it right.”
🦉 Sameer’s Comment
“It’s just an axis — until you use it to show why your electrolyser is outperforming everyone else’s.”
