Drilldown in Map
Closed this issue · 1 comments
Hi @weizhenye
I'm trying to use the Drilldown in Map, but cannot get it working.
like: https://www.highcharts.com/maps/demo/map-drilldown
Do you have a example this? Please.
Tks.
I guess the reason you're not getting it work is the map data file. As I commented, https://code.highcharts.com/mapdata/countries/us/us-all.js
is a JavaScript file, it sets map data to the global variable Highcharts.maps["countries/us/us-all"]
by default, which is not work well with ES6 import. What's more, in your example, drilldown map data is loaded dynamically in runtime like $.getScript('https://code.highcharts.com/mapdata/' + mapKey + '.js', function () {
, which means you must have Highcharts
global variable.
So I have two suggestions:
- Set
Highcharts
towindow
as a global variable after you import highcharts. By this way dynamically loaded map data can be set to your highcharts instance. That may require do some config with webpack. - Go to https://code.highcharts.com/mapdata/ and you can find map data is also provided in GeoJSON format, loading JSON in runtime is more convenient than JavaScript. But cross-origin requests to those GeoJSON is not allowed, so you need to download map data you need and serve them yourself.
