我想为每个条形图绘制一个目标线，如下所示，

的数据
我使用的是Chart Js 4.4。这是我实现条形图的代码。我试图添加另一个数据集，但它没有正确Map。而且x轴标签显示了两次。

var WeeklyData = @Html.Raw(System.Text.Json.JsonSerializer.Serialize(Model.UDTSLDDailyPVA.ToList()))
            console.log(WeeklyData);

        let weeklylabels = [...new Set(WeeklyData.map((x) => x.Day))];
        console.log(weeklylabels);

        let weeklydatasets = (WeeklyData.map((y) => y.TotalActual));
        console.log(weeklydatasets);

        //let weektarget = (WeeklyData.map((y) => y.WeekTarget));
        //console.log(weektarget);

        

        var barChartDataWeekly = {
            labels: weeklylabels,
            datasets: [
                {
                    data: weeklydatasets,
                    backgroundColor: 'rgba(0, 154, 221, 1)'  
                }
            ],
        };

window.onload = function () {
            var ctxUPHHistory = document.getElementById('barChartUPHHistory').getContext("2d");
            window.myBar = new Chart(ctxUPHHistory, {
                type: 'bar',
                data: barChartDataWeekly,
                options: {
                    responsive: true,
                    maintainAspectRatio: false,
                    parsing: {
                        xAxisKey: 'Day',
                        yAxisKey: 'TotalActual'
                    },                        
                    scales: {                            
                        y: {
                            ticks: {
                                beginAtZero: true
                            }
                        }
                    },
                    plugins: {
                        legend: {
                            display: false
                        }
                    }
                }
            });

        };
