How to vary the thickness of doughnut chart, using ChartJs.?

chart.js, javascript

Solution

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
};

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 `%`.
