样条带的样条（Spline with plot bands）
以下是带有绘图带的样条图的示例。
我们已经在Highcharts Configuration Syntax一章中看到了用于绘制图表的配置 。 现在，让我们了解带有绘图带的样条图的示例，其中采用其他配置/步骤。
配置 (Configurations)
使用yAxis.plotBands属性配置波段。 使用'from'和'to'属性设置波段范围。 使用'color'属性设置band的颜色。 使用'label'属性设置band的标签样式。
yAxis
yAxis.setAxisTitleText("Wind speed (m/s)")
.setMin(0)
.setMinorGridLineWidth(0)
.setGridLineWidth(0)
.setAlternateGridColor(null)
.setPlotBands(
yAxis.createPlotBand() // Light air
.setFrom(0.3)
.setTo(1.5)
.setColor(blueColor)
.setLabel(new PlotBandLabel()
.setText("Light air")
.setStyle(new Style()
.setColor("#606060")
)
),
yAxis.createPlotBand() // Light breeze
.setFrom(1.5)
.setTo(3.3)
.setColor(clearColor)
.setLabel(new PlotBandLabel()
.setText("Light breeze")
.setStyle(new Style()
.setColor("#606060")
)
)
);
