我想创建一个如下所示的条形图：

我试着用网站上给出的文档创建一个堆叠条形图。https://www.chartjs.org/docs/latest/samples/bar/stacked.html
但是无法找到按照我要求创建图表的方法。
我试过下面的例子

<canvas id="myChart" style="vertical-align:left;z-index:1; height: 350px"> </canvas>
                            <script type="text/javascript" language="javascript" src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.4/Chart.min.js"></script>
                            <script>
                                var ctx = document.getElementById("myChart").getContext("2d");
                                var myBarChart = new Chart(ctx, {
                                    type: 'bar',
                                    data: {
                                        labels: ['T1', 'T2', 'T3', 'T4'],
                                        datasets: [{
                                        label: 'Done',
                                        backgroundColor: "#caf270",
                                        data: [12, 59, 5, 56],
                                        }, {
                                        label: 'Running',
                                        backgroundColor: "#45c490",

                                        }, {
                                        label: 'Todo',
                                        backgroundColor: "#008d93",
                                        data: [12, 59, 5, 56],
                                        }, {
