Highcharts Gauge Chart

The following example demonstrates a gauge chart.

We have already learned about the basic configuration syntax of Highcharts in previous chapters. Now, let's look at other configurations.

Configuration

chart.type Configuration

Set the chart's type to 'gauge'. The chart.type describes the type of the chart. The default value is "line".

var chart = {
   type: 'gauge'
};

pane Configuration

The pane is applicable only for polar charts and angular gauges. This configurable object holds the general options for combining x and y axes. Each x and y axis can be associated with a pane by index.

var pane = {
  startAngle: -150,  // Starting degree of the x-axis or gauge axis, given in degrees. 0 is north.
  endAngle: 150      // Ending degree of the x-axis or gauge axis, given in degrees. 0 is north.
};
