Highcharts 压缩气泡图不适用于负值

Question

我正在使用高图表打包气泡图，我需要根据其值（负值）显示不同大小的气泡。当我传递正值时它工作正常，但当我传递负值时圆的大小不会改变。有什么方法可以显示带有负值的图表吗？

Highcharts.chart('container', {
    chart: {
        type: 'packedbubble',
        height: '100%'
    },
    title: {
        text: 'TOP Countries'
    },

负值图表

正值图表

Answer 1

属性zMin 和zMax 不是官方packedbubble 系列API 的一部分，但它们在内部使用并且在bubble 系列中工作。

plotOptions: {
    packedbubble: {
        minSize: '30%',
        maxSize: '80%',
        //zMin: 0,
        //zMax: 1000,
        ...
    }
}
