class src.biosim.visualization.Visuals(island, num_years_sim, ymax_animals=None, cmax_animals=None, img_base=None, img_fmt='png')

Class handling the visual presentation, as well as storing of images

Parameters:

• island (object) – Instance of Island
• num_years_sim (int) – Number of years to simulate, used for line graph
• ymax_animals (int or float) – Y-limit for line graph
• cmax_animals (dict) – Density for heat maps with ‘Herbivore’ or ‘Carnivore’ as key
• img_base (path) – Where to store pictures and make movie from
• img_fmt (filetype) – Default: ‘png’

cell_colors

cell type to color name

Type:dict

density_heatmap

animal type to int value

Type:dict

draw_animals_over_time(island)

Draw line graph for herbivores and carnivores over time.

Parameters:island (object) – Instance of Island

draw_geography()

Draws pixels for geography with right colors

draw_geography_exp()

get_data_heat_map(island, data_type)

Could have also used pandas DF to get data.

Parameters:

• island (class instance of Island) –
• data_type (str) – num_animals, num_herbivores or num_carnivores

make_color_pixels(island)

Creates a list indexed by [y][x] that represents an color by type of cell. The color is collected from a class variable called color_params
