class SpiralMesh(x, y, initial_xedges, initial_yedges, min_per_bin=250)

Bases: object

__init__(x, y, initial_xedges, initial_yedges, min_per_bin=250)

property bin_id

property cat

pd.Categorical version of bin_id, with fill bin removed.

property data

property initial_edges

property mesh

property min_per_bin

property cell_filter_thresholds

property cell_filter

Boolean Series identifying properly filled mesh cells.

Series selects mesh cells that meet density and area criteria specified by mesh_cell_filter_thresholds().

Notes

Neither density nor size convert log-scale edges into linear scale. Doing so would overweight the area of mesh cells at larger values on a given axis.

set_cell_filter_thresholds(**kwargs)

Set or update the mesh_cell_filter_thresholds().

Parameters:

• density (scalar) – The density quantile above which we want to select bins, e.g. above the 0.01 quantile. This ensures that each bin meets some sufficient fill factor.

• size (scalar) – The size quantile below which we want to select bins, e.g. below the 0.99 quantile. This ensures that the bin isn’t so large that it will appear as an outlier.
