我正在尝试将数据库中的数据引入此Highcharts树形图，我不知道如何格式化代码的JSON部分。当有一个明确的xAxis和yAxis时，它相对容易。我们使用php汇编程序从查询中获取所有数据。我使用正常工作的JSON直接从Highcharts柱形图中获取代码，我尝试自己更新它并且它一直告诉我$.getJSON位是一个意外的标识符。
$(function () {
// Drop-in fix:
Highcharts.seriesTypes.treemap.prototype.getExtremesFromAll = true;
$('#container').highcharts({
colorAxis: {
minColor: ' #000000',
maxColor: '#ffffff'
},
tooltip: {
backgroundColor: '#fffff',
formatter: function () {
return this.point.name + ":" + this.point.value;
}
}
$.getJSON("/charts/data/homepage-charts-data.php?<?php echo $_SERVER['QUERY_STRING']; ?>", function(json) {
options.categories = json[0]['data'];
options.series[0] = json[1];
chart = new Highcharts.Chart(options);
});
});
});
格式化数据的代码（来自：/charts/data/homepage-charts-data.php）
function displayJsonHomepageBallotMeasuresDataChart ($aaQuery) {
global $NIMSPv4;
$result = $NIMSPv4->query("$aaQuery");
$categories = array();
$categories['name'] = 'Election_Jurisdiction';
$series = array();
$series['name'] = 'Total_$';
while($row = $result->fetch_assoc()) {
$categories['data'][] = $row['Election_Jurisdiction'];
$series['data'][] = $row['Total_$'];
}
$result = array();
array_push($result,$categories);
array_push($result,$series);
print json_encode($result, JSON_NUMERIC_CHECK);
} // END CHART FUNCTION
更新：这是我试图从中提取数据的JSON。 Election_Jurisdiction和Total_ $就是我现在想要访问的内容，考虑到它是一张树形图，我也可以放下候选人和Office_Sought，我需要展示比赛。
