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：
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' |
| } |
| } |
