Hi experts :)

I have a barmark chart with 6 bars. It works fine but I want the first 3 bars to be red and the second 3 bars to be green.

Any idea how I do this?

    struct Item: Identifiable {
        let id = UUID()
        let month: String
        let visitValue: Int
    }

    var myItems = [Item]()
    let items:  [Item] = [

                // Highest perfoming Months
                Item(month: highestLowestMonths.mthHighestName[0],
                visitValue: Int(highestLowestMonths.mthHighestRevenue[0])),

                Item(month: highestLowestMonths.mthHighestName[1],
                visitValue: Int(highestLowestMonths.mthHighestRevenue[1])),

                Item(month: highestLowestMonths.mthHighestName[2],
                visitValue: Int(highestLowestMonths.mthHighestRevenue[2])),

                // Lowest perfoming Months
                Item(month: highestLowestMonths.mthLowestName[0],
                visitValue: Int(highestLowestMonths.mthLowestRevenue[0])),

                Item(month: highestLowestMonths.mthLowestName[1],
                visitValue: Int(highestLowestMonths.mthLowestRevenue[1])),

                Item(month: highestLowestMonths.mthLowestName[2],
                visitValue: Int(highestLowestMonths.mthLowestRevenue[2])),
    ]

    var body: some View {

                Chart {
                    // High and low monthly performers chart
                    ForEach(items) { items in
                        BarMark(
                            x: .value("Month", items.month),
                            y: .value("sales Revenue", items.visitValue)
                        )
                        .foregroundStyle(.green.opacity(0.8))

                        RuleMark(
                            y: .value("xxx", contactAnalyticsDataMonthlyAverages.eaAverageVisitValue)
                            )
                            .foregroundStyle(.gray)
                            .lineStyle(StrokeStyle(lineWidth: 2))
                            .annotation(position: .top, alignment: .leading)
                        {
                                Text("FIXTHIS \(contactAnalyticsDataMonthlyAverages.eaAverageVisitValue, format: .number)")
                                    .font(.system(size: 12, weight: .semibold, design: .rounded))
                                    .foregroundStyle(.blue)
                            }
                    }
                }

                .chartForegroundStyleScale([
                    "zzz": Color(.green)
                     ])
                .chartLegend(position: .top, alignment: .bottomTrailing)
                .chartYAxis(.hidden)

                // Chart has been tapped. display large version.
                .onTapGesture {
                    print("mob: High and low monthly performers chart tapped")
                    showLargeChart = true
                    }
                    .sheet(isPresented: $showLargeChart) {
                    summaryChartLarge()
                    }
            }
        }

Hi Hatsushira, thank you . I did that and now I have a very strange runtime error. I will start a new question for that issue.
