I'm having trouble building a 2 level drilldown chart using the Highcharts API. I am using Jquery's $.getJSON() method which retrieves data from one of my Go methods. For some reason I can't save the data to a javascript variable so I am having to build the chart within the $.getJSON method. I can see that the JSON is being properly displayed when I navigate to that URL. I'm having a lot of trouble manipulating the data to display the proper chart. If someone could please explain/help it would be greatly appreciated as I have been working on this for a while now and I need to get it done for my job. I will try to make this as easy as possible to understand/read. Here is what I have so far:
Go:
type Office struct {
Austin struct {
Balance string
RM struct {
Matt struct {
Balance string
}
John struct {
Balance string
}
Blake struct {
Balance string
}
Jamie struct {
Balance string
}
}
}
ElPaso struct {
Balance string
RM struct {
Brenda struct {
Balance string
}
Ericka struct {
Balance string
}
Nicole struct {
Balance string
}
Stephanie struct {
Balance string
}
Tricia struct {
Balance string
}
Viri struct {
Balance string
}
}
}
ABL struct {
Balance string
RM struct {
BrianABL struct {
Balance string
}
JamieABL struct {
Balance string
}
JohnABL struct {
Balance string
}
MattABL struct {
Balance string
}
TimABL struct {
Balance string
}
}
}
}
func getData(res http.ResponseWriter, req *http.Request) {
office := Office{}
conn, err := sql.Open("mssql", "my db credentials")
if err != nil {
log.Fatal("Open connection failed:", err.Error())
}
defer conn.Close()
rows, err := conn.Query("my select query")
if err != nil {
panic(err.Error())
}
for rows.Next() {
var Austin, ElPaso, ABL, Matt, John, Blake, Jamie, Brenda, Ericka, Nicole, Stephanie, Tricia, Viri, BrianABL, JamieABL, JohnABL, MattABL, TimABL string
rows.Scan(&Austin, &ElPaso, &ABL, &Matt, &John, &Blake, &Jamie, &Brenda, &Ericka, &Nicole, &Stephanie, &Tricia, &Viri, &BrianABL, &JamieABL, &JohnABL, &MattABL, &TimABL)
office.Austin.Balance = Austin
office.Austin.RM.Matt.Balance = Matt
office.Austin.RM.John.Balance = John
office.Austin.RM.Blake.Balance = Blake
office.Austin.RM.Jamie.Balance = Jamie
office.ElPaso.Balance = ElPaso
office.ElPaso.RM.Brenda.Balance = Brenda
office.ElPaso.RM.Ericka.Balance = Ericka
office.ElPaso.RM.Nicole.Balance = Nicole
office.ElPaso.RM.Stephanie.Balance = Stephanie
office.ElPaso.RM.Tricia.Balance = Tricia
office.ElPaso.RM.Viri.Balance = Viri
office.ABL.Balance = ABL
office.ABL.RM.BrianABL.Balance = BrianABL
office.ABL.RM.JamieABL.Balance = JamieABL
office.ABL.RM.JohnABL.Balance = JohnABL
office.ABL.RM.MattABL.Balance = MattABL
office.ABL.RM.TimABL.Balance = TimABL
}
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:
$.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', {
series: [{
type: 'treemap',
layoutAlgorithm: 'squarified',
allowDrillToNode: true,
animationLimit: 1000,
dataLabels: {
enabled: false
},
levelIsConstant: false,
levels: [{
level: 1,
dataLabels: {
enabled: true
},
borderWidth: 3
}],
data: points
}],
subtitle: {
text: 'Subtitle test'
},
title: {
text: 'Title test'
}
});
});
Here is my JSON response from /getdata:
{

"Matt" : {"Balance" : "12345.12"},
