更改ng-charts的图例位置(使用angular2)

Question

如何更改图例的位置(默认情况下显示在图表的顶部)？我正在使用ng-charts,我正在尝试根据文档更改位置,但它似乎不起作用.

该模板包含:

<canvas baseChart
  [datasets]="datasets"
  [labels]="labels"
  [chartType]="type"
  [colors]="colors"
  [legend]="legend"
  [position]="position">
</canvas>

组件变量是:

labels: string[] = [ 'EMI', 'Food', 'Fuel', 'bike' ];
type: string = 'doughnut';
legend: boolean = true;
position: string = 'left';
colors: Color[] = [{}];

datasets: any[] = [{
  data: [ 3350, 5450, 4100, 1000 ],
  backgroundColor: [
    "#FF6384",
    "#36A2EB",
    "#FFCE56"
  ],
  hoverBackgroundColor: [
    "#FF6384",
    "#36A2EB",
    "#FFCE56"
  ]
}];

按照该自述中ng2-charts,你可以使用options变更不暴露任何属性ng2-charts本身.

添加[options]="options"到您的模板,以及options组件的变量:

private options: any = {
  legend: { position: 'left' }
}
