我无法使用Highcharts API构建2级深入分析图表。我正在使用Jquery的$.getJSON()方法，该方法从我的一个Go方法中检索数据。出于某种原因，我无法将数据保存到javascript变量中，因此我必须在$.getJSON方法中构建图表。我可以看到导航到该URL时正确显示了JSON。我在操纵数据以显示正确的图表方面遇到了很多麻烦。如果有人可以请解释/帮助，我会非常感激，因为我已经在这方面工作了一段时间，我需要为我的工作完成它。我将尝试尽可能简单地理解/阅读。以下是我到目前为止的情况：
转到：

func getData(res http.ResponseWriter, req *http.Request) {

}
defer conn.Close()
rows, err := conn.Query("my select query")
if err != nil {

}
for rows.Next() {
var Austin, ElPaso, ABL, Matt, John, Blake, Jamie, Brenda, Ericka, Nicole, Stephanie, Tricia, Viri, BrianABL, JamieABL, JohnABL, MattABL, TimABL string

office.Austin.Balance = Austin
office.Austin.RM.Matt.Balance = Matt
office.Austin.RM.John.Balance = John
office.Austin.RM.Blake.Balance = Blake

office.ElPaso.Balance = ElPaso

}
js, err := json.Marshal(office)
if err != nil {
http.Error(res, err.Error(), http.StatusInternalServerError)
return
}
res.Header().Set("Content-Type", "text/json")
res.Header().Set("Access-Control-Allow-Origin", "*")
res.Write(js)
}
JavaScript的：
$.getJSON('/getdata', function(data) {
for (office in data) {
if (data.hasOwnProperty(office)) {
officeVal = 0;
officeP = {
id: 'id_' + officeI,
name: office,
color: Highcharts.getOptions().colors[officeI]
};
officeBalI = 0;
for (officeBalance in data[office]) {
if (data[office].hasOwnProperty(officeBalance)) {
officeBalanceP = {
id: officeP.id + '_' + officeBalI,
name: officeBalance,
parent: officeP.id
};
points.push(officeBalanceP);
causeI = 0;
for (cause in data[office][country]) {
if (data[office][country].hasOwnProperty(cause)) {
causeP = {
id: countryP.id + '_' + causeI,
name: causeName[cause],
parent: countryP.id,
value: Math.round(+data[office][country][cause])
};
officeVal += causeP.value;
points.push(causeP);
causeI = causeI + 1;
}
}
countryI = countryI + 1;
}
}
for (RM in data[office]) {
if (data[office].hasOwnProperty(RM)) {
RMP = {
id: officeP.id + '_' + RMI,
name: RM,
parent: officeP.id
};
points.push(RMP);
}
}
officeP.value = Math.round(officeVal / countryI);
points.push(officeP);
officeI = officeI + 1;
}
}
Highcharts.chart('container', {

您的JS代码不起作用，它有语法错误。
树的数据结构如下：
data: [{
name: 'I have children',
id: 'id-1'
}, {
name: 'I am a child',
parent: 'id-1',
value: 2
}, {
name: 'I am a smaller child',
parent: 'id-1',
value: 1
}]
所以，你的父母是办公室，他们有价值观，他们的孩子是人，他们也有价值观 - 所以你需要把办公室的人与正确的身份联系起来。例如。像这样：
var points = [];
Object.keys(data).forEach((office, i) => {
var people = data[office]['RM'],
color = Highcharts.getOptions().colors[i],
id = 'id_' + i;
points.push({
name: office,
value: Number(data[office]['Balance']),
id: id,
color: color
});
Object.keys(people).forEach((person, j) => {
points.push({
name: person,
value: Number(people[person]['Balance']),
parent: id,
color: color
});
});
});
