Highcharts - Semi Circle Donut Chart


Advertisements

Following is an example of a basic pie chart.

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

An example of a basic pie chart is given below.

Configurations

Let us now see the additional configurations/steps taken.

series

Configure the series type to be pie based. series.type decides the series type for the chart. Here, the default value is "line". Configure the size of pie using innerSize as innerSize: '50%'.

var series = {
   type: 'pie',
   innerSize: '50%'
};
