public class EChartsGaugeChart extends EChartsChart<EChartsGaugeChart>
A gauge chart implementation for displaying single values within a defined range.

Gauge charts (also known as speedometer or dial charts) are ideal for:

  • Showing progress towards a goal
  • Displaying KPIs and metrics
  • Real-time monitoring dashboards
  • Performance indicators

Features include:

  • Customizable min/max ranges
  • Multiple gauges in one chart
  • Configurable pointer styles
  • Color-coded ranges
  • Labels and value formatting

Example usage: 


 EChartsGaugeChart gaugeChart = new EChartsGaugeChart();
 gaugeChart.setSize(800, 400);

 // Create gauge series
 EChartsGaugeSeries cpuGauge = gaugeChart.createGaugeSeries("CPU Usage");
 cpuGauge.setMin(0);
 cpuGauge.setMax(100);
 cpuGauge.setRadius(120);
 cpuGauge.addData("CPU", 67);
