Gauge charts are a type of chart that displays data using a dial or needle to indicate a value within a specific range. Gauge charts are commonly used to visualize performance metrics, such as speedometers, progress meters, and other KPIs. We typically use gauge charts to represent a single value within a range of values.

Gauge chart - Code

Metric gauge charts​

Metrics gauge charts, also known as dial or speedometer charts, are an effective way to visualize key performance indicators (KPIs) and other metrics. These charts indicate the current value of a metric within a predefined range, often segmented into different zones, e.g. red for poor performance, green for good performance, etc.

Circle gauge charts​

Circle gauge charts, also known as radial progress charts or circular progress bars, are a visually appealing way to represent data and track progress towards a goal. These charts use a circle to display the percentage of completion, making it easy to quickly grasp the status of a project or task. The circle is typically filled in proportion to the progress made, with the center often displaying the percentage value.

Arc gauge charts​

Arc gauge charts, also known as semi-circular progress bars, are a dynamic way to visualize data and track progress. Unlike circle charts, arc gauge charts use a semi-circle or arc to represent the percentage of completion. This design can be particularly effective in dashboards and user interfaces where users need a clear and engaging visual representation but space is limited.

Dos and Don’ts​

  • Do keep it simple and easy to read, with a clear needle and well-defined ranges
  • Do use color coding, e.g. green for good, red for danger, etc. to indicate different ranges
  • Do label ranges and the needle value clearly to avoid confusion
  • Don’t overcrowd the gauge with too many ranges or labels
  • Don’t use gauge charts for visualizing complex data or large datasets
  • Don’t use similar colors for adjacent ranges to avoid confusion
