Javascript在Echart条形图上使用JSON值

Question

我有一个运行php脚本的ajax函数，它返回

下面的JSON值

[{"status":"Cleared","qty":"2"},{"status":"Issued","qty":"3"},{"status":"Rejected","qty":"1"},{"status":"Requested","qty":"2"}]

我需要获取状态和数值在echarts条形图上使用它们，状态为x轴，qty为Y轴。运行以下操作时，不会显示任何图表，也不会在控制台中显示错误。

我的javascript位于

之下

$(document).ready(function(){

$.ajax({
    url: 'php_files/permit_php_files/permit_chart_process.php',
    method: "GET",
    data: {
        access_id: sessionStorage.getItem('access_id'),
        client_id: sessionStorage.getItem('client_id')
    },
    success: function (data) {

        console.log(data);

        require.config({
            paths: {
                echarts: 'js/plugins/visualization/echarts'
            }
        });

        require(
            [
                'echarts',
                'echarts/theme/limitless',
                'echarts/chart/bar',
                'echarts/chart/line'
            ],


            // Charts setup
            function (ec, limitless) {

                var permit_chart = ec.init(document.getElementById('permit_chart'), limitless);


                permit_chart_options = {

                    // Setup grid
                    grid: {
                        x: 40,
                        x2: 40,
                        y: 35,
                        y2: 25
                    },

                    // Add tooltip
                    tooltip: {
                        trigger: 'axis'
                    },

                    },

                    // Enable drag recalculate
                    calculable: true,

                    // Horizontal axis
                    xAxis: [{

                    series: [

                            itemStyle: {
                                normal: {
