我想在测量带上有工具提示或传说。我画了这样的乐队：如何在plotBand上显示工具提示或图例？
plotBands: [{
from: 0,
to: 10,
color: '#55BF3B'
}, {
from: 10,
to: 20,
color: '#DDDF0D'
}]
我想看看mouseover上的工具提示乐队。
或者我想要的另一个解决方案是用关于颜色来显示每个乐队的传说。有传言的选项，但不适用于乐队。
对于plotBands有没有类似showInLegend:true的选项？或者任何其他解决方案来获得这些？
一般情况下，plotBands没有任何工具提示或图例选项，但是可以向plotBand添加一些自定义事件，例如mouseover。请参阅：http://api.highcharts.com/highcharts#xAxis.plotBands.events
因此，您可以为此创建自己的工具提示。
感谢什么答案。你会建议如何在传奇中添加带有颜色和标签的乐队？ – gencay 2013-02-18 14:48:24
可能唯一的两个选择是使用固定的最小/最大或假系列图例（无点）的区域系列，并管理legendItemClick通过删除它来隐藏plotBand。 – 2013-02-19 12:25:37
由于它是（例如）不可能，所以你可以在图表下面放置一个subtitle（在我的情况下，一个表）。例如：
subtitle: {
text: '<span style="background-color: #55BF3B; border-radius: 2px; padding: 1px 2px;">' +
'0-10' +
'</span>' +
'<span style="background-color: #DDDF0D; border-radius: 2px; padding: 1px 2px;">' +
'10-20' +
'</span>',
useHTML: true,
verticalAlign: 'bottom'
}
通过将文本附加到由Highcharts生成的svg路径元素，实际上可以为标准绘图条制作相当优雅的标签。通过这样做，您可以获得实际遵循情节带曲线的文本。仔细查看量表初始化后触发的匿名函数中的代码。您需要获取正确的plotband对象，为path元素分配一个id属性，然后插入text和textPath元素（使用createElementNS）。然后使用xlink命名空间链接新创建的textPath元素。在我的示例中，我正在应用标尺作为标尺周围的标绘带显示的四分位数。
例子：
$(selector).highcharts({
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},

/*the value axis*/
