morris.js解析json字符串错误

Question

我使用morris.js在图表上随时间绘制一些统计数据。

$(document).ready(function() {

  if($('#time-graph').length) {
    var week_data = <?php echo($stat_array)?>;
    Morris.Line({
      element : 'time-graph',
      data : week_data,
      xkey : 'period',
      ykeys : 'temp_avg',
      labels : ['temp_avg','temp_avg'],
      events : ['2014-06-01 00:00:01', '2014-6-30 23:55:55'],
      ymin : -1.0,
      ymax : 50.0
    });
  }

$ stat_array包含一个json字符串，它按照以下方式格式化，在应用程序的早期检索

[{"period":"2014-06-24 18:37:44","temp_avg":"46.845"},{"period":"2014-06-24 18:38:01","temp_avg":"47.28"},{"period":"2014-06-24 18:40:01","temp_avg":"47.185"},{"period":"2014-06-24 18:42:01","temp_avg":"47.4675"},{"period":"2014-06-24 18:44:01","temp_avg":"47.3125"},{"period":"2014-06-24 18:46:01","temp_avg":"48"},{"period":"2014-06-24 18:48:01","temp_avg":"47.2175"},{"period":"2014-06-24 18:50:01","temp_avg":"48"},{"period":"2014-06-24 18:52:01","temp_avg":"48.095"}];

但图表格式不正确，如下所示

如果有人能指出我出错的地方会很棒：D

Answer 1

实际上，你只是缺少一些东西，首先，删除对象上的;分号。

其次，我不知道这是否是一个错字，但你错过了$(document).ready({});的结束。

最后，如果您的数据在某个特定区域混乱，请不要感到惊讶，因为您的数据似乎只有2014-06-24 18:MM:SS个差异。我只是调整了范围，你会清楚地看到线图。 Sample Output

示例：

<?php $stat_array = '[{"period":"2014-06-24 18:37:44","temp_avg":"46.845"},{"period":"2014-06-24 18:38:01","temp_avg":"47.28"},{"period":"2014-06-24 18:40:01","temp_avg":"47.185"},{"period":"2014-06-24 18:42:01","temp_avg":"47.4675"},{"period":"2014-06-24 18:44:01","temp_avg":"47.3125"},{"period":"2014-06-24 18:46:01","temp_avg":"48"},{"period":"2014-06-24 18:48:01","temp_avg":"47.2175"},{"period":"2014-06-24 18:50:01","temp_avg":"48"},{"period":"2014-06-24 18:52:01","temp_avg":"48.095"}]'; ?>
