Amchart 和 Ajax 获取格式不正确的数据

我想使用AmChart并从php获取图表的数据。

这是我的PHP文件：

$colors = Array("#FF0F00","#FF6600","#FF9E01","#FCD202","#F8FF01","#B0DE09","#04D215","#0D8ECF","#0D52D1","#2A0CD0","#8A0CCF","#CD0D74","#754DEB","#DDDDDD","#999999","#333333","#000000");
$datas = $bdd->query("SELECT count(*) as count, rest.name as name
                   FROM command com, zone z, dinningroom dr, restaurant rest
                   WHERE com.zone = z.number
                       AND z.dinningroom = dr.number
                       AND dr.restaurant = rest.number
                   GROUP BY rest.number;");
$i=0;
while($data = $datas->fetch())
{   
    $dataList[$i]=array("name"=>$data['name'],"count"=>$data['count'],"color"=>$colors[$i]);
    $i++;
}
echo json_encode($dataList);
?>

$datas有很好的数据。SQL请求很好，并返回我想要的。

这是我的 JavaScript 和我的 Ajax 请求：

$.ajax({
              url: 'statComPerMenu.php',
              failure: function (data) {
                  alert('fail: ' + data);
              },
              success: function(data) {
                    var statComPerMenuChart;
                    // SERIAL CHART
                    statComPerMenuChart = new AmCharts.AmSerialChart();
                    statComPerMenuChart.dataProvider = data;
                    statComPerMenuChart.categoryField = "name";
                    // the following two lines makes chart 3D
                    statComPerMenuChart.depth3D = 20;
                    statComPerMenuChart.angle = 30;
                    // AXES
                    // category
                    var categoryAxis = statComPerMenuChart.categoryAxis;
                    categoryAxis.labelRotation = 90;
                    categoryAxis.dashLength = 5;
                    categoryAxis.gridPosition = "start";
                    // value
                    var valueAxis = new AmCharts.ValueAxis;
                    valueAxis.dashLength = 5;
                    statComPerMenuChart.addValueAxis(valueAxis);
                    // GRAPH            
                    var graph = new AmCharts.AmGraph();
                    graph.valueField = "count";
                    graph.colorField = "color";
                    graph.balloonText = "[[name]]: [[count]]";
                    graph.type = "column";
                    graph.lineAlpha = 0;
                    graph.fillAlphas = 1;
                    statComPerMenuChart.addGraph(graph);
                    // WRITE
                    statComPerMenuChart.write("chartdiv");
           } //Success
           });
       };

不显示任何图表。

但是，如果我通过以下方式更改变量"数据"： data = [{名称： "toto"， 计数： 10， 颜色： "#FF0F00"}，{名称： "toto"， 计数： 10， 颜色： "#FF0F00"}];从 Ajax 查询成功，这工作正常！我得到图表...

所以问题在于我从 php 文件中获得的格式......我找不到要返回的正确格式。

编辑：如果我这样做：

success: function(data) {
    $("#omg").html(data);
    [...]
    chart.dataProvider = data;
    [...]
}

这打印在页面上：[{"名称"："布鲁塞尔"，"计数"："4"，"颜色"："#FF0F00"}，{"名称"："Chimay"，"计数"："2"，"颜色"："#FF6600"}]并显示一个空图表。

如果复制粘贴打印的表格作为数据：

success: function(data) {
    $("#omg").html(data);
    [...]
    chart.dataProvider =  [{"name":"Brussels","count":"4","color":"#FF0F00"},{"name":"Chimay","count":"2","color":"#FF6600"}];
    [...]
}

图表显示良好。
