我正在尝试将带有三个变量的json文件加载到HighMap中。
在我修订的JSON中，我包括三列： 1.代码2.价值3.中位数工资
我能够通过main.js加载JSON文件，但是添加了Median Wage，地图失去了它的渐变，我无法在悬停显示框中为Median Wage开始一个新行。
HighCharts的演示如下： http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/maps/demo/color-axis/
非常感谢任何输入。
谢谢！

答案 0 :(得分：0)
问题是你使用Code和Value参数而不是小写。因此，如果您更换它，并将有关中位数的信息添加到pointFormat，那么一切都会有效。
数据：
{
"code": "AL",
"value": 11.8,
"MedianW": 40120
}
工具提示：pointFormat: '{point.code}: {point.value}/km² : MedianW: {point.MedianW}'
