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' } } }] };
