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'
}
}
