将 json 结果呈现为 div 中的饼图 - highmaps
Rendering json results to a pie chart in a div - highmaps
我建了this electoral map,但点击地图区域时在pop-up对话框中绘制双方饼图没有成功。正在传递对话框标题,但未传递应构建聊天的实际值。
返回的 json data is here 而我只想在有人单击地图上的县时将 pie-chart 推送到对话框。这是我的代码和 "pointClick" 函数,它们应该将饼图渲染为 div。
$(function() {
$.getJSON("<?= base_url('index.php/presidential/getByCounty'); ?>", function(json) {
function pointClick(json) {
var row = this.options.row,
$div = $('<div></div>')
.dialog({
title: ([this.name]),
width: 400,
height: 300
});
//THIS IS ACTUALLY WHAT'S NOT WORKING
window.chart = new Highcharts.Chart({
chart: {
renderTo: $div[0],

width: 370,

您的 JSON 数据包含字符串格式的数字,因此将其转换为 Number
像这样
series: [{
name: 'Votes',
data: [{
name: 'nasa',
color: '#0200D0',
y: Number(this.nasa) //transform to number
}, {
name: 'jubilee',
color: '#C40401',
y: Number(this.jubilee) //transform to number
}],
dataLabels: {
format: '<b>{point.name}</b> {point.value:.1f}%'
}
}]
