        try
        {
            IEnumerable<Booking> list = _bookingDataService
                .Query(d => d.BookingDate.Month < (DateTime.Now.Month));

            IEnumerable<int> data_month = list.Select(d => d.BookingDate.Month)
                .Distinct().Take(4);

            StatusSummaryRecentReports obj = new StatusSummaryRecentReports();
            //obj.Total_Order_ByMonth = Total_PriceOreder_Each_Month;
            //obj.Months = Months;

            return Json(obj);

        }
        catch (Exception ex)
        {
            Response.StatusCode = (int)HttpStatusCode.BadRequest;
