带有绘图带的样条图
以下是带有绘图带的样条图示例。
我们已经在 Highcharts 配置语法 章节中看到了用于绘制图表的配置。 现在，让我们了解一个带有绘图带的样条图示例，其中采取了额外的配置/步骤。
配置
使用 yAxis.plotBands 属性配置图带区。 使用"from"和"to"属性设置图带范围。 使用 'color' 属性设置图带的颜色。 使用"label"属性设置图带标签的样式。
yAxis
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: {
