如何调整图表空间和图例标签的大小

Question

我在角度2中使用ng2-chart，如何调整空间图表和图例标签的大小？非常感谢你。

HTML

<div align="center" style="width: auto; height: auto">
  <div class="chartArea">
    <canvas baseChart id="chartBalanceId" [data]="chartData"
            [labels]="chartLabels" 
            [colors]="chartColors"
            [options]="chartOptions"
            [chartType]="chartType"></canvas>
  </div>
</div>

组件

private chartData: number[] = [];
  private chartType: string = "doughnut";
  private chartOptions: any = {legend: {position: "right"}};
  private chartLabels: string[] = ["BTC", "ETH", "LTC", "XRP"];
  private chartData = [30, 34, 30, 6];
  private chartColors: any[] = [{ backgroundColor: ["#b8436d", "#00d9f9", "#a4c73c", "#a4add3"] }];

元素将填充块大小，因此不要使用style="width: auto; height: auto"将它们放入具有固定宽度的div中。
