如何组合到chartjs宽度php的数组

我需要帮助如何使数组数据的php代码到chartjs，我使用2表，我希望生成如下数组代码

function revenueCost(year) {
    $.ajax({
        headers: {
            'X-CSRF-TOKEN': $('meta[name=\'csrf-token\']').attr('content')
        },
        url: url,
        data: {
            year: $('#year').val(),
        },
        type: 'POST',
        dataType: 'JSON',
        success:function(data){
            // console.log(data);
            $('#revenue-cost').empty();
            var myChart = new Chart(document.getElementById('revenue-cost'), {
                type: 'bar',
                data: {
                    labels: data.label,
                    datasets: [{
                        label: 'Revenue',
                        data: data.revenue,
                        borderWidth: 0.5,
                        borderColor: '#00642c',
                        backgroundColor: 'rgba(0,100,44,0.2)'
                    },{
                        label: 'Cost',
                        data: data.cost,
                        borderWidth: 0.5,
                        borderColor: '#a80e19',
                        backgroundColor: 'rgba(168,14,25,0.2)'
                    }]
                },
                options: {
                    scales: {
                        yAxes: [{
                            ticks: {beginAtZero: true}
                        }]
                    }
                }
            });
        },
    });
}

我想制作这样的数组

{"label":["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"],"revenue":[105,85,55,68,72,8,0,0,0,0,0,0],"cost":[41,32,22,23,26,3,0,0,0,0,0,0]}

像这样的图表视图

在我看来，解决方案可能很简单：

向PHP文件发送POST HTTP请求

验证您是否有带有if语句和isset（$\u POST）的POST请求

准备或提取数据，并创建与下一个类似的关联数组：

如果在数组之间划分数据，只需将它们与数组合并，并将结果存储在新变量中

最后，在$.ajax中捕获响应，并执行您想要对数据执行的操作

我希望这些信息对你有用

$label_data = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"];
$revenue_data = [105,85,55,68,72,8,0,0,0,0,0,0];
$cost_data = [41,32,22,23,26,3,0,0,0,0,0,0];

$data = [
    'label'   => $label_data,
    'revenue' => $revenue_data,
    'cost'    => $cost_data
];

echo json_encode($data);

$label_first = ["Jan","Feb","Mar","Apr","May","Jun"];
$label_second = ["Jul","Aug","Sep","Oct","Nov","Dec"];
$label_data = array_merge($label_first, $label_second );
