Chart.js v2: space between doughnut inside doughnut

Question

I am using chart.js v2.5.0. I put doughnut inside doughnut.

I want the disdance between 2 doughnuts(A) to be larger without affecting the distance betwe

Answer 1

To make it work with the latest ChartJS 2.7.2, I've just copied the source as suggested from https://github.com/chartjs/Chart.js/blob/master/src/controllers/controller.doughnut.js. Then I added the patch:

if (me.index > 0) {
  me.outerRadius -= opts.datasetRadiusBuffer;
  me.innerRadius -= opts.datasetRadiusBuffer;
}

Everything was working as expected.
