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。
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, |
