我是 json 新手，我想创建一个 HighChart，我有 JSON 格式的数据，我已将其转换为表格格式 [下面是从 JSON 中提取的数据和列]。

地点日期范围点击次数

雅虎搜索 2010-04-01 2172
谷歌 2010-04-01 10830
MSN 2010-04-01 555
SSP 2010-04-01 0
雅虎搜索 2010-04-02 1746
谷歌 2010-04-02 8508
MSN 2010-04-02 477
谷歌 2010-04-03 5061
雅虎搜索 2010-04-03 1113
MSN 2010-04-03 192

我想以以下格式创建一个 JSON 字符串。我该怎么做 

xAxis: {categories: ['2010-04-01', '2010-04-02', ' 2010-04-03']},
series: [{
                name: 'Yahoo Search',
                data: [2172 ,1746,1113]
            }, 
{
                name: 'Google',
                data: [10830,8508,5061]
            },
 {
                name: 'MSN',
                data: [555,477,792]
            }, 
{
                name: 'SSP',
                data: [0,0,0]
            }]

我的 json 数据在这里

您可以使用以下函数将现有的 JSON 字符串转换为新的 JSON 字符串：

function makeJSONstring(jsonstr) {
    var rows = JSON.parse(jsonstr).rows;
    console.log(rows);
    var data = [];
    for (var i=0; i<rows.length; i++) {
        data.push({
            Venue: rows[i].f[0].v,
            DateRange: rows[i].f[1].v,
            Clicks: rows[i].f[2].v | 0
        });
    }
    //console.log(data);
    var out = {
        xAxis: {
            categories: [ /*'2010-04-01', '2010-04-02', ' 2010-04-03'*/ ]
        },
        series: [ /*{ name: 'Yahoo Search', data: [2172 ,1746,1113] } , etc. */ ]
    };
    var cat = {}, ser = {}; // temporary variables
    for (i = 0; i < data.length; i++) {
        // data[i].Vanue , data[i].DateRange , data[i].Clicks
        if (cat[data[i].DateRange] === undefined) {
            cat[data[i].DateRange] = true;
            out.xAxis.categories.push(data[i].DateRange);
        }
        if (ser[data[i].Venue] === undefined) {
            ser[data[i].Venue] = out.series.length;
            out.series.push({
                name: data[i].Venue,
                data: [data[i].Clicks]
            });
        } else {
            var index = ser[data[i].Venue];
            out.series[index].data.push(data[i].Clicks);
        }
    }
    //console.log(out);
    return JSON.stringify(out);
}
