Simulation is run until stop condition is met which corresponds to the number of hours (calendar.count) between starting (calendar.init) and ending date (calendar.last) as specified in the configuration above. The output of simulation is snap-ped each day, not by every hour, to reduce overhead.
r = simulate(Garlic.Model; config, stop = "calendar.count", snap = 1u"d")

The output data frame can be now used for making some plots. Here is a plot replicating Fig. 3.D from the paper showing leaf development over time.
visualize(r, :time, [:leaves_appeared, :leaves_mature, :leaves_dropped]; kind = :line)
Another plot replicating Fig. 4.D from the paper showing the area of green leaf taking account of leaf aging.
visualize(r, :time, :green_leaf_area; kind = :line)
Similarly, dry biomass of organ types per plant can be visualized.
visualize(r, :time, [:leaf_mass, :bulb_mass, :total_mass]; kind = :line)
For more information about using the framework such as simulate() and visualize() functions, please refer to the Cropbox documentation.
