Javascript Chart.js条形图-多个数据集标签

我目前使用chart.js制作了以下条形图

使用以下代码：

var ctx = document.getElementById("lea-comparison");

var data = {
    labels: ["City of London", "Tower Hamlets", "Nottingham", "Birmingham", "S Gloucestershire", "Poole", "Wokingham"],
    datasets: [
        {
            label: "Schools funding by LEA",
            backgroundColor: [
                'rgba(255, 99, 132, 0.2)',
                'rgba(255, 99, 132, 0.2)',
                 'rgba(75, 192, 192, 0.2)',
                'rgba(75, 192, 192, 0.2)',
                'rgba(153, 102, 255, 0.2)',
                'rgba(153, 102, 255, 0.2)',
                'rgba(153, 102, 255, 0.2)'],
            borderColor: [
                'rgba(255,99,132,1)',
                'rgba(255,99,132,1)',
                 'rgba(255, 206, 86, 1)',
                'rgba(255, 206, 86, 1)',
                 'rgba(75, 192, 192, 1)',
                'rgba(75, 192, 192, 1)',
                'rgba(75, 192, 192, 1)', ],
            borderWidth: 1,
            data: [8595, 7014, 5309, 5218, 4196, 4194, 4158],
        }
    ]
};

var myBarChart = new Chart(ctx, {
    type: 'horizontalBar',
    data: data,
});

在伦敦的

最佳资助学校

标签旁边，我可以再添加两个标签，并在黄色和蓝色条上标注文字吗

我尝试添加另外两个数据集，但结果是这样的 用堆叠的钢筋

编辑：3个数据集的代码如下所示

var data = {
    labels: ["City of London", "Tower Hamlets", "Nottingham", "Birmingham", "S Gloucestershire", "Poole", "Wokingham"],
    datasets: [
        {
            label: "Best funded schools in London",

            backgroundColor: [
                'rgba(255, 99, 132, 0.2)',
                'rgba(255, 99, 132, 0.2)',
],
            borderColor: [
                'rgba(255,99,132,1)',
                'rgba(255,99,132,1)',
],
            borderWidth: 1,
            data: [8595, 7014],
        },
                {
            label: "Best funded schools outside London",

            backgroundColor: [

                 'rgba(75, 192, 192, 0.2)',
                'rgba(75, 192, 192, 0.2)'
],
            borderColor: [

                 'rgba(255, 206, 86, 1)',
                'rgba(255, 206, 86, 1)'],
            borderWidth: 1,
            data: [5309, 5218],
        },
                {
            label: "Poorly funded schools in England",

            backgroundColor: [

                'rgba(153, 102, 255, 0.2)',
                'rgba(153, 102, 255, 0.2)',
                'rgba(153, 102, 255, 0.2)'],
            borderColor: [

                 'rgba(75, 192, 192, 1)',
                'rgba(75, 192, 192, 1)',
                'rgba(75, 192, 192, 1)',],
            borderWidth: 1,
            data: [4196, 4194, 4158],
        }
    ]
};

这就是我所期待的：

您希望得到什么，第二个的代码是什么样子的@Gacci：我已经添加了3个数据集的代码和预期的条形图，谢谢
