Module: Clowk::Phlex::Charts::Format

Defined in:
lib/clowk/phlex/charts/format.rb

Overview

Format — magnitude-adaptive decimal formatting for chart labels, headline values and tooltips (ex-MetricFormat). A flat "%.1f" floors sub-0.1 values to "0.0", which makes an idle series read as zero even when the curve clearly moves — the shape is right but every number lies. These tiers keep enough precision for the magnitude you're looking at.

>= 100  → 0 decimals    ("142")
>= 10   → 1 decimal     ("42.5")
>= 1    → 1 decimal     ("4.2")
>= 0.01 → 2 decimals    ("0.05")
> 0     → "<0.01"
= 0     → "0"
