高图中的动态悬停颜色

Question

我使用highmap，我想在高图显示状态下悬停时制作动态不同颜色。

因为你可以看到不同的颜色，这就是我所做的

var usMapChart ,  data = [] ;
var  mapData = Highcharts.geojson(Highcharts.maps['countries/us/custom/us-small']);
var UsMapdata = ([
	{"value": 3,"code": "ma",'hovercolor':'#d8077a'},

  我搜索了很多，但没有找到，所以请帮助我。 我在网上找到了一些解决方案，但它只适用于最新版本的旧版本的高版本。

Answer 1

我不确定它是否是Highcharts 5中的错误，但似乎设置一个点的状态不起作用。

您可以包装负责在更改状态时设置图形属性的方法。

var H = Highcharts;

H.wrap(H.seriesTypes.map.prototype, 'pointAttribs', function(p, point, state) {
  console.log(point);
  var attr = p.call(this, point, state),
      states = point.states,
      hover = states && states.hover;

  if (state === 'hover' && hover && hover.color) {
    attr.fill = hover.color ;
  }

  return attr;
})

并配置一个点：

var UsMapdata = ([{
  "value": 3,
  "code": "ma",
  states: {
    hover: {
      color: 'red'
    }
  }
}]);

我在Highcharts github上报告了这种行为。
