Polymer with highmaps:cannot read 属性未定义的 mapChart

Question

我正在尝试使用 jsfiddle 在 highmap 上提供聚合物包装 http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/maps/demo/mappoint-latlon/ 但它抛出一个错误无法读取属性未定义的 mapChart，有人可以提供一个使用 polymer 的 highmap 的工作 jsfiddle 吗？

Answer 1

您的图表初始化代码有误。阅读文档 here.

更改您的代码

$(this.$.container).Highcharts.mapChart('container', {

到

Highcharts.mapChart(this.$.container, {

或者，

$(this.$.container).highcharts('Map', {

那就可以了。
