How to plot a simple model field

How to plot a simple model field using chartjs?

I have the folllowing model:

class RoomValue(models.Model):
    time = models.DateTimeField(auto_now_add=True)
    temperature = models.FloatField()
    humility = models.FloatField()
    light = models.FloatField()

I would like just to plot time vs temperature. How can I do that?

I tried the following:

class RoomTemperatures(ReportView):
    report_model = RoomValue
    date_field = "time"
    chart_engine = "chartsjs"

    chart_settings = [
        Chart(
            "Room temperature",
            Chart.LINE,
            data_source=["temperature"],
            title_source=["time"],
            plot_total=True,
        ),
    ]

Thank you very much!
