  return (

      <Pie data={jiraticketsData.pie_chart} />
      </div>
  )
}


export default defects

我正在尝试访问pie_chart数组数据：

Pie chart array

这是ChartComponent代码，如果需要的话：

import * as React from "react";
import * as chartjs from "chart.js";

export type ChartDataFunction<T extends chartjs.ChartData> = (
  element: HTMLElement
) => T;
export type ChartData<T extends chartjs.ChartData> = ChartDataFunction<T> | T;

export interface ChartComponentProps {
  data: ChartData<chartjs.ChartData>;
  type?: chartjs.ChartType;
  getDatasetAtEvent?(e: any): void;
  getElementAtEvent?(e: any): void;
  getElementsAtEvent?(e: any): void;
  height?: number;
  legend?: chartjs.ChartLegendOptions;
  onElementsClick?(e: any): void; // alias for getElementsAtEvent (backward compatibility)
  options?: chartjs.ChartOptions;
  plugins?: object[];
  redraw?: boolean;
  width?: number;
  datasetKeyProvider?: (any: any) => any;
}

export interface LinearComponentProps extends ChartComponentProps {
  data: ChartData<chartjs.ChartData>;
}

export default class ChartComponent<
  P extends ChartComponentProps
> extends React.Component<P,{}> {
  chartInstance: chartjs;
}

export class Doughnut extends ChartComponent<ChartComponentProps> {}

export class Pie extends ChartComponent<ChartComponentProps> {}

export class Line extends ChartComponent<LinearComponentProps> {}

export class Scatter extends ChartComponent<ChartComponentProps> {}

export class Bar extends ChartComponent<LinearComponentProps> {}

export class HorizontalBar extends ChartComponent<ChartComponentProps> {}

export class Radar extends ChartComponent<ChartComponentProps> {}

export class Polar extends ChartComponent<ChartComponentProps> {}

export class Bubble extends ChartComponent<ChartComponentProps> {}

export var defaults: {
  global: chartjs.ChartOptions & chartjs.ChartFontOptions;
  [key: string]: any;
};
