php - 如何从php发送json到highcharts

我正在尝试通过jQuery ajax调用从php调用传递json到highcharts对象。

这是PHP脚本的回报

[{"name":"Positive","data":"[1426896000000,0.5,1],[1427760000000,0.333333333333,1],[1427846400000,0.333333333333,1],[1427932800000,0.353553390593,1],[1428278400000,0.408248290464,1],[1428364800000,0.301511344578,1],[1428451200000,0.377964473009,1],[1428537600000,0.686886723927,2],[1428624000000,2.38658259877,7],[1428710400000,0.4472135955,1],[1428883200000,0.333333333333,1],[1429142400000,0.333333333333,1],[1429574400000,0.316227766017,1],[1429747200000,1.10948233661,2],[1429833600000,0.408248290464,1],[1429920000000,1.34375333838,3],[1430092800000,1.13976615407,3]"},{"name":"Negative","data":"[1427673600000,-0.353553390593,1],[1428105600000,-0.353553390593,1],[1428278400000,-1.0850712542,3],[1428537600000,-1.20901527656,3],[1428624000000,-0.377964473009,1],[1428883200000,-0.353553390593,1],[1429056000000,-0.408248290464,1],[1429574400000,-0.377964473009,1],[1429660800000,-0.353553390593,1],[1429747200000,-1,3],[1429833600000,-1.02022005726,3],[1429920000000,-0.755928946018,2],[1430006400000,-0.632455532034,1]"}]

我使用以下方法调用getChart：

function getChart(searchstring){
$.ajax({
    type: "GET",
    url: "searchString.php",
    dataType: "json",
    data: {name:searchstring},
    success: function(news) {
        renderPosNegChart(news);
    }
  });
}
function renderPosNegChart(data){
var newschart = {
    chart: {
        type: 'spline'
    },
    title: {
        text: "Test"
    },
    xAxis: {
        type: "datetime"
    },
    yAxis: {
    },
    series: [data[0]]
}
$("#newschart").highcharts(newschart);

}

不幸的是，它显示的只是：

最终，我希望它同时显示“正”和“负”行。我在网上跟踪了一堆教程，但是并没有帮助。

如果我可以澄清任何事情，请告诉我。

最佳答案

每个系列数据应该是一个数组数组，而不是字符串。

例：

[{"name":"Positive","data":[[1426896000000,0.5,1], ... ,[1430006400000,-0.632455532034,1]]}]
