✅

since version 2 the field has been renamed to cutoutPercentage.

cutoutPercentage
Number 50 – for doughnut, 0 – for pie
The percentage of the chart that is cut out of the middle.

It can be used like this

var options = {        
    cutoutPercentage: 40
};

more details here
http://www.chartjs.org/docs/#doughnut-pie-chart-chart-options

Update: Since version 3

var options = {        
    cutout: 40
};

According to the documentation at release notes of 3.x

Doughnut cutoutPercentage was renamed to cutout and accepts pixels as numer and percent as string ending with %.

If you are using chart.js for Angular via ng2-charts you would do something like this in your component.html file: 

// component.html file

<canvas baseChart [options]='chartOptions'>
</canvas>

// Do note that other required directives are missing in this example, but that I chose to highlight the 'options' directive

And do something like this in your component.ts file:

//component.ts file

chartOptions = {
  cutoutPercentage: 80
};

A helpful source of information: available chart directives and config options for the [options] directive

I wanted to add how to achieve this exactly in React.

this.myChart = new Chart(this.chartRef.current, {
  type: 'doughnut',
  options: {
    cutout:120
  },
  data: {
    labels: this.props.data.map(d => d.label),
    datasets: [{
      data: this.props.data.map(d => d.value),
      backgroundColor:  Object.values(CHART_COLORS)
    }]
  }
});}

In ng2-chart v3 with new types, in configraution option need to add chart type;

**ChartConfiguration<'doughnut'>['options']** 


doughnutChartOptions: ChartConfiguration<'doughnut'>['options'] = {
    cutout: '50%', // percentage of chart to cut out of the middle
    //cutout: 100, // pixels
};

For vue-chartjs (tested with Nuxt), if setting options doesn’t work, try :

Chart.defaults.doughnut.cutoutPercentage = 80

Note that it will change all the doughnuts cutout.
