    var hours: List[String] = ["9am", "12pm", "3pm", "6pm", "9pm"]

    var x = List[String]()
    var y = List[String]()
    var counts = List[Float64]()
    for day_i in range(len(days)):
        var is_weekend = day_i >= 5
        for hour in hours:
            x.append(days[day_i])
            y.append(hour)
