Я хочу отобразить карту в своем проекте React, она выглядит так:
https://www.highcharts.com/docs/maps/latlon
Я видел руководство, но я хочу использовать его в реакции. руководство все о родном html / js.
и я увлекся, здесь есть реактивная оболочка:
https://github.com/highcharts/highcharts-react
Я попытался использовать это для создания демонстрационного приложения. И вот мой файл .js:
import React from "react";
import { Component } from "react";
import { render } from "react-dom";
import Highcharts from "highcharts";
import HC_map from "highcharts/modules/map";
import HighchartsReact from "highcharts-react-official";
import mapData from "./mapdata.js";
import usaMapData from "./UsaMapData.js";
import usaBubbleData from "./usaBubbleData";
HC_map(Highcharts);
const mapOptions = {
title: {
text: "Map-Demo"
},
tooltip: {
formatter: function() {
return (
this.point.capital +
", " +
this.point.parentState +
"<br>Lat: " +
this.point.lat +
" Lon: " +
this.point.lon +
"<br>Population: " +
this.point.population
);
}
// crosshairs: [
// {
// zIndex: 5,
// dashStyle: "dot",
// snap: false,
// color: "gray"
// },
// {
// zIndex: 5,
// dashStyle: "dot",
// snap: false,
// color: "gray"
// }
// ]
},
mapNavigation: {
enabled: false
},
series: [
{
name: "Basemap",
mapData: usaMapData,
borderColor: "#606060",
nullColor: "rgba(200, 200, 200, 0.2)",
showInLegend: false
},
{
name: "Separators",
type: "mapline",
// data: H.geojson(usaMapData, "mapline"),
color: "#101010",
enableMouseTracking: false
},
{
type: "mapbubble",
dataLabels: {
enabled: true,
format: "{point.capital}"
},
name: "Cities",
data: usaBubbleData,
maxSize: "12%",
color: "#7cb5ec"
}
]
};
export default class Mapdemo extends Component {
// eslint-disable-next-line no-useless-constructor
constructor(props) {
super(props);
}
render() {
// console.dir(dataBubble);
return (
<div>
<HighchartsReact
highcharts={Highcharts}
constructorType={"mapChart"}
options={mapOptions}
/>
</div>
);
}
}
но синий пузырь не отображается на экране. Я получил только серую карту США.
и я сравниваю код с демо источника ниже:
(с официального сайта highmaps)
$(function () {
var H = Highcharts,
map = H.maps['countries/us/us-all'],
chart;
// Add series with state capital bubbles
$.getJSON('https://data.jianshukeji.com/jsonp?filename=json/us-capitals.json&callback=?', function (json) {
var data = [];
$.each(json, function (ix, entry) {
entry.z = entry.population;
data.push(entry);
});
$('#container').highcharts('Map', {
title: {
text: 'Highmaps lat/lon demo'
},
tooltip: {
formatter: function () {
return this.point.capital + ', ' + this.point.parentState + '<br>Lat: ' + this.point.lat + ' Lon: ' + this.point.lon + '<br>Population: ' + this.point.population;
},
crosshairs: [{
zIndex: 5,
dashStyle: 'dot',
snap: false,
color: 'gray'
}, {
zIndex: 5,
dashStyle: 'dot',
snap: false,
color: 'gray'
}],
},
mapNavigation: {
enabled: true
},
series: [{
name: 'Basemap',
mapData: map,
borderColor: '#606060',
nullColor: 'rgba(200, 200, 200, 0.2)',
showInLegend: false
}, {
name: 'Separators',
type: 'mapline',
data: H.geojson(map, 'mapline'),
color: '#101010',
enableMouseTracking: false
}, {
type: 'mapbubble',
dataLabels: {
enabled: true,
format: '{point.capital}'
},
name: 'Cities',
data: data,
maxSize: '12%',
color: H.getOptions().colors[0]
}]
});
chart = $('#container').highcharts();
});
// Display custom label with lat/lon next to crosshairs
$('#container').mousemove(function (e) {
var position;
if (chart) {
if (!chart.lab) {
chart.lab = chart.renderer.text('', 0, 0)
.attr({
zIndex: 5
})
.css({
color: '#505050'
})
.add();
}
e = chart.pointer.normalize(e);
position = chart.fromPointToLatLon({
x: chart.xAxis[0].toValue(e.chartX),
y: chart.yAxis[0].toValue(e.chartY)
});
chart.lab.attr({
x: e.chartX + 5,
y: e.chartY - 22,
text: 'Lat: ' + position.lat.toFixed(2) + '<br>Lon: ' + position.lon.toFixed(2)
});
}
});
$('#container').mouseout(function (e) {
if (chart && chart.lab) {
chart.lab.destroy();
chart.lab = null;
};
});
});

если я закомментирую свойство данных в серии (тип: "mapbubble"), то я получу абсолютно такой же результат с моим собственным кодом. так что ошибка может быть здесь. но я сравниваю usaBubbleData с data в демоверсии, это те же данные. Я скопировал их из демо.
вот мой usaBubbleData:
