Highcharts 标示区曲线图
Highcharts 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'
}
}
}]
};
