Question

我正在尝试将json数据提供给高图，但图表显示为空白，这就是我需要的示例：http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/column-rotated-labels/

values.php生成json输出

[["10000164@example",4],["10000166@example",2],["10000173@example",1],["10000177@example",3]]

您可以在回调函数中构建图表，而不是先定义所有选项吗？也许尝试这样的事情：

$.getJSON('values.php', function (json) {

        $('#container').highcharts({
            series: [{
              data: json
            ]},
            title: {
              text: 'Some Title'
            },
            subtitle: ...

我无法演示ajax请求，但是如果你将json直接放在数据选项中，那么图表会呈现如下： jsfiddle
