Semi Gauge

The Semi Gauge is a variation of the gauge chart that displays values using a semi-circular dial. It is commonly used to show progress toward a goal, performance against thresholds, or KPI tracking in a compact and intuitive format.

The semi-gauge uses a needle to indicate the current value against a defined range, with additional support for target markers, ranges, and gradient backgrounds.

Best Situations to Use

Use the Semi Gauge when you want to:

  • Track progress toward a KPI or target in a clear, visual way.

  • Provide an at-a-glance performance indicator with ranges (e.g., red/yellow/green).

  • Use a compact alternative to a full circular gauge.

  • Add a speedometer-style display for operational metrics.

Not Recommended for:

  • Comparing multiple categories side by side (use bar or line charts instead).

  • Trend analysis across time periods.

Example Configurations

  1. Basic Semi Gauge

    • Single range color with ticks enabled.

    • Shows value and target with needle indicator.

  2. Multi-Range Semi Gauge

    • Uses red/yellow/green ranges for poor, average, and good performance.

    • Includes units in title (e.g., Utilization %).

  3. Styled Semi Gauge

    • Gradient background, custom center color, and bold labels.

    • Formatter applied for monetary values (e.g., $250K).

Notes

  • Semi Gauges are ideal for executive dashboards where KPIs must be easily understood.

  • Use contrasting colors for ranges and needle to improve readability.

  • Limit the number of ranges (3–5 recommended) to avoid clutter.

  • Formatter properties ensure values are displayed in a business-relevant format.
