Question

任何人都可以在这里分享来自外部json文件的数据的基本高图代码吗？

我尝试阅读与我的帖子相关的所有材料，但我仍然无法使用 getJSON 创建高级图表，希望有人可以在这里与我分享您的想法，谢谢。

这是我的json文件的一部分：

  [
     {
         "indicator": "ClassC",
         "month": 201611,
         "ww": 201648,
         "test_time": 0.0,
         "p": 48.0,
         "Product": "RB"
     },
     {
         "indicator": "ClassC",
         "month": 201612,
         "ww": 201649,
         "test_time": 47.48,
         "p": 48.0,
         "Product": "RB"
     },
     ...
 ]

Answer 1

请检查这个小提琴。你可能会发现答案就在这里

https://jsfiddle.net/gh/get/jquery/1.7.2/highcharts/highcharts/tree/master/samples/highcharts/demo/line-basic/

并检查那里使用的api。你可以找到返回的json格式

https://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?.

更新代码

$.getJSON('your url', function (data) {
var datas = JSON.parse(data)
var myArray = [];
for(var i in datas ) {
    myArray.push(datas[i]);
}
var mydata = myArray.map(i=>([i.month,i.p]));

    // Create the chart
    Highcharts.stockChart('container', {


        rangeSelector: {
            selected: 1
        },

        title: {
            text: 'AAPL Stock Price'
        },

        series: [{
            name: 'AAPL',
            data: mydata,
            tooltip: {
                valueDecimals: 2
            }
        }]
    });
});

var datas部分应该替换为$ .getJson

中的数据
