我正在尝试使用highcharts-chart
指令在Highmaps中部署美国县地图。这在美国州地图上工作正常,但是在遇到编译错误时,在定义美国县的数据元素时遇到了问题。
这是尝试:
HTML
<highcharts-chart
[Highcharts]="Highcharts"
[constructorType]="'mapChart'"
[options]="chartMap"
[(update)]="updateFlag"
[oneToOne]="true"
style="width: 500px; height: 400px; display: block;"
></highcharts-chart>
打字稿
import * as Highcharts from 'highcharts';
import MapModule from 'highcharts/modules/map';
const mapX = require('@highcharts/map-collection/countries/us/us-all-all.geo.json')
MapModule(Highcharts);
.....
.....
this.chartMap = {
chart: {
map: mapX
},
title: {
text: 'THIS IS THE US COUNTIES MAP'
},
series: [{ // <-- error is thrown here
name: 'Unemployment',
borderWidth: 0.5,
states: {
hover: {
color: 'red'
}
},
joinBy: ['hc-key', 'code'],
data: [
{
"code": "us-al-001",
"name": "Autauga County, AL",
"value": 3.9
},
{
"code": "us-al-003",
"name": "Baldwin County, AL",
"value": 4.3
}
]
}]
};
我收到以下编译错误:
键入'{name:string; borderWidth:数字;状态:{悬停:{颜色: 串; }; }; joinBy:字符串[];数据:{“代码”:字符串; “名称”: 串; “值”:数字; } []; }'无法分配给type 'SeriesAbandsOptions | SeriesAdOptions | SeriesAoOptions | SeriesApoOptions | SeriesAreaOptions | SeriesArearangeOptions | SeriesAreasplineOptions | SeriesAreasplinerangeOptions | ...另外82个 ... | SeriesZigzagOptions”。类型“ { 名称:字符串; borderWidth:数字;状态:{悬停:{颜色:字符串; }; }; joinBy:字符串[];数据:{“代码”:字符串; “ name”:字符串; “值”:数字; } []; }',但必须输入 'SeriesXrangeOptions'.ts(2322)highcharts.d.ts(335083,5):'类型'为 在这里声明。
此错误是什么以及如何解决?
答案 0 :(得分:1)
发生此错误是因为您没有设置使用TypeScript时每个系列所必需的系列type
。
series: [{
name: 'Unemployment',
type: 'map', // type is required for each series
borderWidth: 0.5,
states: {
hover: {
color: 'red'
}
},
joinBy: ['hc-key', 'code'],
data: [{
"code": "us-al-001",
"name": "Autauga County, AL",
"value": 3.9
},
{
"code": "us-al-003",
"name": "Baldwin County, AL",
"value": 4.3
}
]
}]
