Fusioncharts中没有数据显示错误

Question

[我使用ajax绘制图表。我有两个文件index.php，selectchart.php。在index.php中，我使用ajax绘制图表。

<div class="chart-area">
                   <div id="chart-1"><!-- Fusion Charts will render here--></div>

                   <div id="chart-mon"><!-- Fusion Charts will render here--></div>

上面，图表1 div用于年度报告，然后我们选择图表将按选择显示的月份。

              </div>

<p><select class="btn btn-light btn-icon-split" id="country" name="country">
<option>--Select Month--</option>
              <option value="01">JAN</option>
              <option value="02">FEB</option>
              <option value="03">MAR</option>
              <option value="04">APR</option>
              <option value="05">MAY</option>
              <option value="06">JUN</option>
              <option value="07">JUL</option>
              <option value="08">AUG</option>
              <option value="09">SEP</option>
              <option value="10">OCT</option>
              <option value="11">NOV</option>
              <option value="12">DEC</option>
              </select></p>

Javascript

<script type="text/javascript">
    $('#country').change(function() {
        var selectedcountry = $(this).children("option:selected").val();
        //alert(selectedcountry);

            $.ajax({
                type : "POST",
                url  : "selectchart.php?country="+selectedcountry,
                data : selectedcountry,
                success: function(result)
                   {
                   $("#chart-1").hide();
                   //$("#myDiv").show();
                   alert(result);
               var myChart = new FusionCharts("column2D", "myThird", 400, 300, "json", result);

              myChart.render("chart-mon");

                    }
                  });

    });
</script>

我已经警告显示[objectoject]的结果。但是在chart-mon中没有显示任何数据。但是我运行selectchart.php

selectchart.php

include("includes/fusioncharts.php"); 

$selectdata = $_REQUEST['country'];

   $dbhandle = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_DATABASE);
   if ($dbhandle->connect_error) {
    exit("There was an error with your connection: ".$dbhandle->connect_error);
   }

        $strQuerymon = "SELECT name, amount FROM income WHERE month = '$selectdata'ORDER BY amount DESC LIMIT 10";
       $resultmon = $dbhandle->query($strQuerymon) or exit("Error code ({$dbhandle->errno}): {$dbhandle->error}");


        if ($resultmon) {

            $arrDatamon = array(
                "chart" => array(

                  "showValues" => "0",
                  "theme" => "zune"
                )
            );

            $arrDatamon["data"] = array();
            while($rowmon = mysqli_fetch_array($resultmon)) {
            array_push($arrDatamon["data"], array(
                "label" => $rowmon["name"],
                "value" => $rowmon["amount"]
                )
            );
            }


            $jsonEncodedDatamon = json_encode($arrDatamon);

            echo $jsonEncodedDatamon;

header('Content-type: text/json');


        }



{"chart":{"showValues":"0","theme":"zune"},"data":[{"label":"washing","value":"1000"},{"label":"cleanin","value":"444"},{"label":"rwr","value":"333"},{"label":"sample","value":"300"},{"label":"werew","value":"33"},{"label":"demo","value":"10"}]} these values are displayed.[enter image description here][1]
