get_riverplot_baseline

outbreak_tools.get_riverplot_baseline(prevalences, loads, k=128)

Find a baseline for drawing a river plot (a shifted scaled stacked area plot) that minimizes visual shear.

Parameters

• prevalences -- pandas df of lineage prevalences over time (See lineage_cl_prevalence())

• loads -- pandas series of viral loads or other scaling data.

• k -- number of iterations to run.

Returns

a pandas series representing the vertical offset of the bottom edge of the river plot.
