Angular Highcharts:具有旋转标签的柱状图(Column with rotated labels)

  以下是带有旋转标签的柱形图示例。

dataLabels

  dataLabels是处理图表中数据标签的包装对象。

  文本旋转度。请注意,由于结构更加复杂,背景、边框和填充将在旋转的数据标签上丢失。这默认为0。

dataLabels = {
   enabled: true,
   rotation: -90,
   color: '#FFFFFF',
   align: 'right',
   format: '{point.y:.1f}', // one decimal
   y: 10, // 10 pixels down from the top
   style: {
      fontSize: '13px',
      fontFamily: 'Verdana, sans-serif'
   }
}
