图表js不显示数据

Question

我正在尝试使用图表js在我的视图中显示来自控制器的数据;现在我只得到图表的模板，但没有数据显示。 这是控制器中的方法：

kubectl describe pod c80b7631698

Events:
  Type     Reason                Message
  ----     ------                -------
  Normal   Pulling               pulling image "gcr.io/my-api:latest"
  Warning  Failed                Failed to pull image "gcr.io/my-api:latest": rpc error: code = Unknown desc = Error: Status 429 trying to pull repository my-api: "Quota Exceeded."
  Warning  Failed                Error: ErrImagePull
  Normal   BackOff               Back-off pulling image "gcr.io/my-api:latest"
  Normal   SandboxChanged        Pod sandbox changed, it will be killed and re-created.
  Warning  Failed                Error: ImagePullBackOff

在我的视图中我有这段代码：

public IEnumerable<DateTime> EachDay(DateTime from, DateTime thru)
        {  
            for (var day =from.Date; day.Date <= thru.Date; day = day.AddDays(1))
                yield return day;
        }
        public ActionResult Dashboard()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Dashboard(DateTime ddebut, DateTime dfin)
        {
            Réception_phosphateEntities db = new Réception_phosphateEntities();

            List<Réception_camions> listréception = db.Réception_camions.ToList();         
            List<Wagons> listwg = db.Wagons.ToList();               
            List<Consommation> co = db.Consommation.ToList();

            List<Double?> stock = new List<Double?>();
            List<DateTime?> dates = new List<DateTime?>();

             foreach (DateTime date in EachDay(ddebut, dfin))
            {
                var stk = listwg.Where(x => x.Date_culbutage <= date.Date).Select(x => x.Poids).Sum()
                    + listréception.Where(x => x.Date_d_arrivée <= date.Date).Select(x => (double)x.Poids_cam).Sum()
                    - co.Where(x => x.Date_consommation <= date.Date).Select(x => x.Qtité_consommée).Sum();

                dates.Add(date);
                stock.Add(stk);
                return View();
            }


            ViewBag.date = dates;
            ViewBag.stk = stock;
            return View();
        }

        var stock=@Html.Raw(Json.Encode(ViewBag.stk));
        var dates=@Html.Raw(Json.Encode(ViewBag.date));
        var ctx = $("#bar_chart");
        var bacChart = new Chart(ctx,{
            type: 'bar',
            data: {
                labels: dates,
                datasets: [{
                    label: "bar chart example",
                    data: stock,
                   
                }]
            }
        })
  

我没有找到问题出在哪里，谢谢你的帮助。
