Angular Highcharts - Pie Chart with Legends

Following is an example of a Pie Chart with Legends.

We have already seen the configurations used to draw a chart in Highcharts Configuration Syntax chapter.

An example of a Pie Chart with Legends is given below.

Configurations

Let us now see the additional configurations/steps taken.

chart

Configure the chart type to be 'pie' based. chart.type decides the series type for the chart. Here, the default value is "line".

var series = {
   type: 'pie'
};

plotOptions

Configure the plotOptions to have legends in pie chart using plotOptions.pie.showInLegend attribute.

plotOptions : {
   pie: {
      allowPointSelect: true,
      cursor: 'pointer',
      dataLabels: {
         enabled: false           
      },
      showInLegend: true
   }
}
