Question

我正在尝试使用角度绘制直方图。以下jsfiddle链接仅供参考。我试图为角度直方图高图创建一个系列对象，以匹配示例中显示的对象。我当前的代码给我一个错误，无法设置undefined的属性名称。在for循环中的第一个属性赋值中发生此错误。有些人可以告诉我哪里出错了吗

Answer 1

我只想在一个声明中创建对象

// First, make the chartSeries an empty array
chartSeries: any[] = [];

for(let i=0; i<this.results.length; i++)
{
  let objHistogram = {
    name: "Histogram" + i,
    type: "histogram",
    xAxis: 1,
    yAxis: 1,
    baseSeries: "s"+i,
    zIndex: -1
  }

  let objectData = {
    name: "Data" + i,
    showInLegend: false,
    data: this.results[i].data,
    id: "s"+i
  };

  // I dont know what you want the chartSeries array to look like, but you may as well just push onto the array.
  this.chartSeries.push(objHistogram);
  this.chartSeries.push(objectData);
}

无法将属性指定为角度未定义
