Highcharts不呈现

Question

我正在尝试使用带有symfony2的ObHighcharts包。

基本上，它会生成以下代码：

 $(function () {
var chart = new Highcharts.Chart({
chart: {"renderTo":"dailyChart","type":"spline"},
series: {"name":"My spline","data":
[
    [1369519200,"2055.5"],
    [1370469600,"1986.3"],
    [1369087200,"1804.0"],
    [1368655200,"1783.3"],
    [1366840800,"1734.3"],
    [1369000800,"1693.2"],
    [1368309600,"1515.4"],
*lots of other similar data*
]
}, 
title: {"text":"My Chart"},
xAxis: {"title":{"type":"datetime","title":"Date"}},
yAxis: {"title":{"title":"Sugar, mg","min":0}}
});
});

但是当我尝试渲染它时，只有一个标题，一个导出按钮和一个空白屏幕。控制台没有显示错误的迹象。这可能有什么不对？感谢任何意见。

Answer 1

因为您的数据元素是一个字符串：

[
    [1369519200,"2055.5"],
    [1370469600,"1986.3"],
    [1369087200,"1804.0"],
    [1368655200,"1783.3"],
    [1366840800,"1734.3"],
    [1369000800,"1693.2"],
    [1368309600,"1515.4"],
*lots of other similar data*
]

应该是[1369519200,2055.5]之类的东西。 您还需要将系列元素括在括号中：

series: [{"name":"My spline","data":
[
    [1369519200,"2055.5"],
    [1370469600,"1986.3"],
    [1369087200,"1804.0"],
    [1368655200,"1783.3"],
    [1366840800,"1734.3"],
    [1369000800,"1693.2"],
    [1368309600,"1515.4"],
]}
]

另请注意，您的时间元素不是按升序排列的。对于正确的日期时间轴，您需要进入升序时间。
