Highcharts 标示区曲线图

以下实例演示了标示区曲线图。

我们在前面的章节已经了解了 Highcharts 配置语法。接下来让我们来看下如何配置。


配置

使用 yAxis.plotBands 属性来配置标示区。区间范围使用 ‘from‘ 和 ‘to‘ 属性。颜色设置使用 ‘color‘ 属性。标签样式使用 ‘label‘ 属性。

配置信息:

var yAxis = {
   title: {
      text: ‘Wind speed (m/s)‘
   },
   min: 0,
   minorGridLineWidth: 0,
   gridLineWidth: 0,
   alternateGridColor: null,
   plotBands: [{ // Light air
      from: 0.3,
      to: 1.5,
      color: ‘rgba(68, 170, 213, 0.1)‘,
      label: {
         text: ‘Light air‘,
         style: {
            color: ‘#606060‘
         }
      }
   }, { // Light breeze
      from: 1.5,
      to: 3.3,
      color: ‘rgba(0, 0, 0, 0)‘,
      label: {
         text: ‘Light breeze‘,
         style: {
            color: ‘#606060‘
         }
      }
   }, { // Gentle breeze
      from: 3.3,
      to: 5.5,
      color: ‘rgba(68, 170, 213, 0.1)‘,
      label: {
         text: ‘Gentle breeze‘,
         style: {
            color: ‘#606060‘
         }   
      }
   }, { // Moderate breeze
      from: 5.5,
      to: 8,
      color: ‘rgba(0, 0, 0, 0)‘,
      label: {
         text: ‘Moderate breeze‘,
         style: {
            color: ‘#606060‘
         }
      }
   }, { // Fresh breeze
      from: 8,
      to: 11,
      color: ‘rgba(68, 170, 213, 0.1)‘,
      label: {
         text: ‘Fresh breeze‘,
         style: {
            color: ‘#606060‘
         }
      }
   }, { // Strong breeze
      from: 11,
      to: 14,
      color: ‘rgba(0, 0, 0, 0)‘,
      label: {
         text: ‘Strong breeze‘,
         style: {
            color: ‘#606060‘
         }
      }   
   }, { // High wind
      from: 14,
      to: 15,
      color: ‘rgba(68, 170, 213, 0.1)‘,
      label: {
         text: ‘High wind‘,
         style: {
            color: ‘#606060‘
         }
      }
   }]
};
