Codex Zone Gauge
by Nexus Codex
Semicircular gauge with danger, warning, and success zones. Animated needle, optional target.
A semicircular zone gauge for Power BI — show a value within configurable danger, warning, and success zones, ideal for operational dashboards where a quick visual read of "is this OK?" is more important than the exact number.
Codex Zone Gauge replaces the standard Power BI gauge with a zone-coloured semicircle that uses position and colour to communicate status, not a needle in space.
New in v2: background transparency to sit over any report canvas and conditional-formatting (fx) rules on zone and marker colours.
IDEAL FOR
- Operational health monitoring
- Service level dashboards (zone = SLA tier)
- Performance dashboards with red / amber / green logic
- Scoreboard tiles where the read is "in the green" or "in the red"
- Replacing speedometer-style gauges with a more honest, more compact alternative
KEY FEATURES
- Configurable zone breakpoints and colours (danger / warning / success)
- Optional needle marker showing current position
- Configurable background, label, and value styling
- Smooth animated transitions on update (respects prefers-reduced-motion)
- Full font controls on every text element
- Optional internal title with full font and alignment controls
- Hover tooltip showing value, zone, and zone thresholds
- Click to cross-filter other visuals
- Background colour with 0–100% transparency — sits cleanly on any report canvas
- Conditional formatting (fx) on zone and marker colours — drive colours from measures or rules
- High contrast mode support
PRO TIP
Use measure-driven zone breakpoints rather than fixed thresholds. That way seasonal or business-cycle shifts can update the gauge's red / amber / green ranges without redesigning the visual.
