Highcarts：帮助创建JSON

只需测试Highchars库（http://www.highcharts.com/）。Highcarts：帮助创建JSON

我需要这个页面的同一个图：http://www.highcharts.com/demo/line-time-series

我有这个表：

+-------------+------------------+ 
| amountFinal | date_transaction | 
+-------------+------------------+ 
| 10.00  | 2015-07-15  | 
| 1415.00  | 2015-07-16  | 
| 1545.00  | 2015-07-17  | 
| 1309.00  | 2015-07-18  | 
| 97.00  | 2015-07-20  | 
| 1625.00  | 2015-07-21  | 
| 1248.00  | 2015-07-22  | 
| 752.00  | 2015-07-23  | 
| 2199.00  | 2015-07-24  | 
| 2370.00  | 2015-07-25  | 
| 1141.00  | 2015-07-27  | 
| 1873.00  | 2015-07-28  | 
| 4275.00  | 2015-07-29  | 
+-------------+------------------+

这是我的JavaScript部分（相同的例子）：

$.getJSON(chart_url, function (data) { 

      $(container_chart).highcharts({ 
       chart: { 
        zoomType: 'x' 
       }, 
       title: { 
        text: 'USD to EUR exchange rate over time' 
       }, 
       subtitle: { 
        text: document.ontouchstart === undefined ? 
          'Click and drag in the plot area to zoom in' : 'Pinch the chart to zoom in' 
       }, 
       xAxis: { 
        type: 'datetime' 
       }, 
       yAxis: { 
        title: { 
         text: 'Exchange rate' 
        } 
       }, 
       legend: { 
        enabled: false 
       }, 
       plotOptions: { 
        area: { 
         /*fillColor: { 
          linearGradient: { 
           x1: 0, 
           y1: 0, 
           x2: 0, 
           y2: 1 
          }, 
          stops: [ 
           [0, Highcharts.getOptions().colors[0]], 
           [1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')] 
          ] 
         },*/ 
         marker: { 
          radius: 2 
         }, 
         lineWidth: 1, 
         states: { 
          hover: { 
           lineWidth: 1 
          } 
         }, 
         threshold: null 
        } 
       }, 

       series: [{ 
        type: 'area', 
        name: 'USD to EUR', 
        data: data 
       }] 
      }); 
     });

无论JSON创建方法我使用，我有一个空白图表（根本没有数据，没有标签，什么也没有）。

E.g.我想：

foreach ($result as $key=>$value) { 

        $date = (strtotime($value['date_transaction']))*1000; //convert from Unix timestamp to JavaScript time 
     $point = $value['amountFinal']; 
     $data[] = "['$date', $point]"; 

     } 

echo json_encode($result);

或者直接用于测试：

$data[] = "[Date.UTC(2015, 10, 16), 5]"; 
     $data[] = "[Date.UTC(2015, 10, 17), 7.5]"; 
     $data[] = "[Date.UTC(2015, 10, 18), 1440.0]"; 

     header("content-type: application/json"); 
     echo "data(".join($data,',').")";

感谢您的支持！

这是在Firebug我的JSON，选项卡的 “答案”：

, 656.00])

CONSOLE.LOG打印相同。

这是PHP代码，将打印数据：

foreach ($result as $key=>$value) { 

      $date = (strtotime($value['date_transaction']))*1000; //convert from Unix timestamp to JavaScript time 

      $point = $value['amountFinal']; 
      $data[] = "['$date', $point]"; 

     } 

     header("content-type: application/json"); 
     echo "data(".join($data,',').")";

这是空白图表的形象！

'的console.log（数据）'... – epoch

这里贴上您的JSON响应，并且如果JS控制台任何错误 –

@NishithChaturvedi在js控制台中没有错误。来自Firebug的响应粘贴。 – sineverba

的问题是，你的JSON是带引号的发送时间戳“”意味着它发送的字符串，而应该是一个数字。

它不应该像

['1436918400000', 10.00]OR "[1437004800000, 1415.00]"

，但像这样\

[[1436918400000, 10.00],[1437004800000, 1415.00]] //and so on
