Map

Matplotlib maps can be constructed through the Map object. Matplotlib automatically creates a color ramp using a continual color range. The continual range of colors can be quite useful for distinguishing different values. A Map object accepts the following parameters:

• attribute is the the fully qualified opus path of the indicator.
• scale is a two element list that specifies the min and max values for the scale of the values on the map. It is optional and defaults to the min/max values of the indicator.

An example:

Map( 
    source_data = source_data,
    dataset_name = 'zone',
    name = 'my_population_at_zone_level',
    attribute = 'urbansim.zone.population',
    years = [2010, 2020], 
    scale = [-5000, 250000]
)
