Stroke width bug when override draw event function in Pie Chart

[ravillarreal]

When setting the donutWidth parameter to the value 30 the actual stroke-width of the donut is not 30px. Causing the donut expand out of the container div

This happens only when you override the draw event function

Try changing the donutWidth option and you'll see the actual stroke-width is incorrect

Of course you could solve this by setting a custom stroke-width inside the draw event like this

chart.on('draw', function(context) {
  if (context.type === "slice") {
    context.element.attr({
      style: "stroke-width: 30px;"
    });
  }
})
