Highcharts 标签旋转柱形图

Highcharts 柱形图Highcharts 柱形图

以下实例演示了标签旋转柱形图。

我们在前面的章节已经了解了 Highcharts 基本配置语法。接下来让我们来看下其他的配置。在 dataLabels 中添加 rotation 属性：

配置

dataLabels : 数据标签

dataLabels 定义图上是否显示数据标签。

文本旋转程度由 rotation 属性决定。我们还可以通过其他属性来定义文本标签的背景，间隔，边框等。 

dataLabels = {
   enabled: true,
   rotation: -90,
   color: '#FFFFFF',
   align: 'right',
   format: '{point.y:.1f}', // 一个小数
   y: 10, // 从上到下 10 像素
   style: {
      fontSize: '13px',
      fontFamily: 'Verdana, sans-serif'
   }
}
