我只是从 jqplot 切换到 highcharts，因为我找不到 jqplot 问题的答案。

我的问题：我想从 json 字符串中绘制以下结果。此字符串包含以下格式的数据对：（yyyy00kw年份为 4 位，00 用于填充，周数为 2 位）和一个值（可以格式化为浮点数）。因为该x对的值可能会更改为yyyymmdd(year month day) 或yyyywwdd(year week day) 它必须是一个字符串。

我的 json 字符串包含以下内容：

这是我的javascript代码：

<script class="code" type="text/javascript">
  var data = [];
  var chart;
  $(document).ready(function() {
    //hier geht es los
    $.getJSON("120925_sql_bauen.php", function(json) {
      chart = new Highcharts.Chart({
        chart: {
          renderTo: 'chart1',
          type: 'line'
        },
        title: {
          text: 'Wetterdatenprojekt'
        },
        xAxis: {
          //categories: []
        },
        yAxis: {
          title: {
            text: 'aktuelle Wetterwerte'
          },
          plotLines: [{
            value: 0,
            width: 1
          }]
        },
        series: json
      });
    });
  });
</script>

不幸的是，highcharts 没有显示任何情节。我希望，highcharts 在字符串方面没有与 jqplot 相同的问题 :-(

问题是您尝试直接使用您的回复。您需要“删除”一层数组。那data应该是json[0]

我更新了我的例子：http: //jsfiddle.net/GgNmY/2/

关于前面的注意，值应该是数字仅适用于 Y 轴（至少在早期版本的 Highcharts 中）。

编辑：这里是提取数据点（值）和类别。

var data = [];
var cats = [];
json[0].forEach(function(point){
    data.push(point[1]);
    cats.push(point[0]);
});

这是一个运行示例：http: //jsfiddle.net/GgNmY/3/

在 Highchart 中，您可以以 JSON 输入的形式设置您的系列：数据对象。在这种情况下，如果 JSON 输入采用以下形式：

[
[1,12],
[2,5],
[3,18],
....
[10,22]
]

然后可以在图表定义中添加以下属性：

series:[{
       data: json
}]

这是正在运行的JSFiddle示例
