I am trying to Sum the SwiftData Ints found on the same date and display the result in a chart.

The following shows the individual records on the date in a chart just fine, I just need to add them before displaying the point.

Any help?

Here is my code.
Thanks.
Blessings,

@Query(filter: #Predicate<Register>
           { $0.sundayAdded  }, sort: [SortDescriptor(.date)]
    ) var fetchedData: [Register]

Chart(fetchedData) { item in
                        if item.sundayAdded {
                            LineMark(
                                x: .value( "Date", item.date, unit: .day),
                                y: .value( "ASA", Double(item.sunCount))).opacity(0.3)
                            
                            PointMark(
                                x: .value( "Date", item.date, unit: .day),
                                y: .value( "ASA", Double(item.sunCount)))
                            .annotation {
                                Text("(item.sunCount)")
                                    .font(.caption2)
                            }
                        }
                    }
