How to inject data into chartjs plugin function?

Question

I have the following chart with plugin function:

this.doughnutChart = new Chart(this.doughnutCanvas.nativeElement, {

  type: 'doughnut',
  plugins: {
    beforeDraw: function (chart) {
      //I want to use data here
    }
});

Data from a provider:

  constructor(public dataService: Data)

And data is easily accessible from the class where chart and plugin is located, but I dont know how to inject it inside of plugin function.

我已经找到了答案，一切都在'chart'参数的最深处：

chart.config.config.data.someData;
