Highcharts - Solid Gauge Chart
We have already seen the configuration used to draw a chart in Highcharts Configuration Syntax chapter.
An example of a Solid Gauge Chart is given below.
Configurations
Let us now see the additional configurations/steps taken.
chart.type
Configure the chart type to be gauge based. Set the type as 'solidguage'.
var chart = { type: 'solidguage' };
pane
This type applies only to polar charts and angular gauges. This configuration object holds general options for the combined X and Y axes set. Each xAxis or yAxis can reference the pane by index.
var pane = { startAngle: -150, endAngle: 150 };
