circumference option in 'chart.options' is undefined

I don’t know if this a bug or I misunderstood the documentation.

The pie/doughnut charts have got some specific options, like , circumference.

From documentation the circumference has got a default of 360 and I’m expecting that when I’m invoking chart.options.circumference I’ll get 360 if I didn’t set it in the configuration of chart:

var myChart = new Chart(ctx, {
    type: 'pie',
    data: {
      labels: ["Jan", "Feb", "Mar"],
      datasets: [{
        label: 'dataset',
        data: [51, 23, 24],
        backgroundColor: 'lightGrey'
      }]
   },
});
console.log(myChart.options.circumference); // <- my expectation is to see 360. Unfortunately is undefined.

It’s not clear to me where I’m wrong.

Was looking at the wrong part of documentation: https://www.chartjs.org/docs/master/charts/doughnut/#dataset-properties

When I override the circumfrence in the options it shows so it looks like it tries to read the option before it got merged https://codepen.io/leelenaleee/pen/RwoQMOJ

Ok… ignore my previous post. You marked as bug therefore the answer is clear.
